Frequently Asked Questions (FAQ)

With our 3D Virtual Try-On tool, you can upload a video of yourself to get a realistic 180-degree view of how a frame will look and fit on your face. Uploading a video is easy—the hard part is deciding which frame to buy when you can try on up to 50 frames!

Click here to get started.

We also offer a 2D try-on feature called Zenni Frame Fit™, for those who just want to upload a picture and get a basic idea of how a frame will look. Click here to use Zenni Frame Fit™.

We encourage you to create your own video for the 3D try-on, but it’s not required. However, using a 3D Virtual Try-On of yourself will be a much better guide to how the glasses will look and fit on your face than using a photo of a model. After clicking “CREATE A TRY-ON,” you may need to allow your device access to the camera. Tips on creating the video:

- A light or plain background is best, such as a white wall behind you.

- Record a video of yourself turning your head side-to-side as instructed. While doing this, you will want to make sure that your head is straight on and level, with your pupils clearly visible.

- Use a standard card (such as a credit card), and place it against your forehead as instructed in order to make sure the glasses are scaled to the right size (you may skip this step, but we encourage you to do it for best fit).

Voila, your 3D Virtual Try-On is complete! To see yourself in glasses, click “TRY ON” on a product detail page, choose the image of yourself, and then move your mouse (or swipe for mobile) left and right on the Try-On image to see yourself from different angles in the frame. To compare yourself wearing different pairs, click "TRY ON" on a product listing page, or in your Favorites, for a static front view to see what looks best.

Yes! If you don’t like the results of a video you took, you may redo it. Go to your Account Overview, click "My TryOn" and then "CREATE NEW VIRTUAL TRY ON."

Yes. We will not use or distribute any images or videos that you upload to our Virtual Try-On or Frame Fit tools.

Our Face Shape Guide features tools to help you discover what your face shape is, as well as links to flattering frames by face shape for men and women.

It depends on what features you are looking for. The following categories can help with your decision:

Weight: If you want a super light frame, go with one that's 15 grams or lower. Titanium frames are generally very light.

Material: You have the choice between metal or plastic. Metal tends to be lighter. Plastic frames tend to be more durable.

Flexibility: This is a nice feature to have for kids or sports glasses. We have a line of kids plastic flexible frames that are forgiving and durable.

Color: Plastic frames tend to come in more color options, especially acetate plastic.

Hypoallergenic: Stainless steel, titanium, and acetate frames are hypoallergenic.

Most of our frames come in one size, but not all. The details will be listed under the product description. Please use the size filter to find the one that best suits you.

Yes, we offer a great selection of universal bridge fit also known as low bridge fit or Asian fit frames. Check out our selection by clicking here.

Non-Zenni frames: Some frames have a series of numbers printed on the inside of a temple arm (the part that goes behind your ear). The first numbers are typically the manufacturer’s style number and a color code. But farther down the temple arm, there may be important numbers that refer to the dimensions of the frame. These numbers are the measurement, in millimeters, of the lens width, nose bridge width, and temple arm length. Often the lens width and nose bridge width are 2-digit numbers separated by a square, and a temple arm length is a 3-digit number in front of or behind the others. Knowing these numbers can help you choose a frame similar in size when shopping.

Zenni Frames: You will find a frame number that consists of 6 or more numbers which will help you locate the frame on the Zenni website.

Your Rx may be too strong for half-rim or rimless glasses, so full-rim would be your option. Full-rim glasses, especially in the nerd-chic look, are very popular. They are generally more durable than half-rim or rimless frames. Half-rim frames are great for people with slim faces. They show more of your face than full-rim frames, and are more durable than rimless glasses. Rimless glasses are great for people who will treat their glasses delicately, and who want their glasses to be practically invisible on their face.

Most of our frames come in multiple colorways. If a frame comes in more than one color, you will see the options on the frame’s product description page.

Yes. When a frame is out of stock, you will see an "out of stock" message below the frame. Enter your email address in the space provided, and we'll let you know when the item becomes available.

Our custom engraving feature can be added to many of our acetate and plastic frames as long as the temple arms are wide enough. The easiest way to find eligible frames is to use the filter tool and select “Custom Engraving” under Feature.

It depends on the frame whether text or icons can be engraved, as well as placement options (inside the temple arm or outside).

To see what content is allowed, please see our custom engraving guidelines here.

New glasses often need minor tweaks to fit your face right. It’s best to have an optician fine-tune the glasses for you, but you can also make adjustments yourself with our How to Adjust Your Glasses guide.

Our ANSI Z87.1 safety glasses are made for working in an area that has particles, flying objects, or dust. If you work in this type of environment, your employer may require you to wear ANSI Z87.1 safety glasses.

The American National Standards Institute is a private, non-profit organization that creates quality and safety standards for a wide variety of products, including safety eyewear. Its standard for eye protection, ANSI Z87. 1, establishes the criteria for using, testing, marking, choosing, and maintaining eye protection to prevent or minimize injuries from eye hazards.

The following frame styles are ANSI Z87.1: 7494, 7496, 7497, 7498, 7499.

We offer prescription single-vision and progressive lenses in polycarbonate, Trivex®, and Blokz® Trivex® lenses. Our Trivex and Blokz Trivex lens options are also available in a gray sunglass tint.

Yes, we offer Trivex® and Blokz® Trivex® lenses in a gray sunglass tint for ANSI Z87.1 Safety Glasses.

Z87.1 glasses will be designated with a “Z87-2+” or “Z87+” marking on the frame. Your prescription lenses will also be etched with “Zenni+” to designate the safety rating as required by ANSI.

ASTM International, is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. ASTM F803 refers to protective eyewear standards for various sports. F803 is the strictest standard for protective eyewear. For glasses to meet the ASTM F803 standard, they need to pass a high velocity impact resistance test, including clarity and strength of the lenses.

Recreation and sports activity are responsible for thousands of eye injuries every year. Approximately 90% of all eye injuries can be easily avoided if wearing appropriate eye protection, like those with ASTM F803 designation.

All of our ASTM tested goggles are tagged as “Sport Protective”. The compliance standards, as well as the sports for which the product has been tested for, will be outlined on the product description page and the accompanying insert card shipped with the goggles.

Only the approved impact-resistant Polycarbonate and Trivex® lenses are offered for this line of products.

We currently offer the following models:

7435 - available in 3 color options
7434 - available in 3 color options
7433 - available in 3 color options

Refer to the following chart to see what size is appropriate for you.

Model# 7435	Model# 7434	Model# 7433
Large (Size 60)	Medium (Size 55)	Small (Size 50)
Adult Large	Adult Medium	Adult Small
	Kids Large	Kids Medium

*Note: Due to the wrap of the sport protective goggle frame, please add 2-3mm to the lens diameter of your current pair of glasses to find your best fit.

Our Sport Protective Goggles 7435, 7434 and 7433 meet and exceed ASTM F803-19 standards for several sports including: basketball, soccer, badminton and handball

They are also great for outdoor activities such as cycling, skating and running, as well as for active youth or adults who may need eyewear that offers additional strength, padding and protection.

Yes.

Sport Protective Goggles can accommodate most prescriptions.

Polycarbonate and Trivex® are the only lens choices available for prescription Sport Protective Goggles due to the impact-resistant quality of the lens material.

If you need glasses, your eye doctor will provide you with a prescription for corrective lenses. Eyeglass prescriptions may be written in different ways, though most are either printed or handwritten in horizontal rows. The first row is the prescription for the right eye (OD), and the second row is for the left eye (OS). Within each of these rows are three values: Sphere (SPH), Cylinder (CYL), and Axis. The SPH number corrects for nearsighted [indicated with a minus (-)] or farsighted [indicated with a plus (+)] vision. The CYL number and AXIS number correct for astigmatism. You may also have another field labeled as ADD which corrects for the reading power used in a bifocal or progressive lens. To learn more about how to read your prescription, click here. Lastly, eyeglass prescriptions sometimes include the pupillary distance (PD) measurement, which is the distance between your pupils. PD is needed to determine where the optical center of the lens will be for clear, accurate vision. If your prescription does not include your PD, you can measure it yourself with our guide here. An eyeglass prescription will usually expire in 1-2 years, depending on which state you received your eye exam.

Here is a list of some optical abbreviations that will help you order your glasses from Zenni Optical:

ADD (also NV-ADD): the Near Vision (NV) Reading ADDition correction on a multifocal Rx. Can be used for bifocal or progressive glasses, or for single-vision reading or computer (intermediate) vision glasses.

AR: Anti-Reflective. A coating that reduces reflection on the lenses.

AXIS: the angle at which the Cylinder (CYL) is placed on a lens to correct an astigmatism. It ranges from 1 to 180.

BAL: the Rx calls for balance lenses, meaning the same Rx for each eye. Often used when a person has no sight in one eye, so both lenses will have the same thickness.

BD, BI, BO, BU: a prism correction on your Rx (may be indicated with Δ, and one of these four abbreviations. The B stands for base, and it could be base down (BD), base in (BI), base out (BO), or base up (BU).

CYL: the Cylinder. Combined with the AXIS, the CYL corrects an astigmatism.

DS: the abbreviation for diopter simplex. An eye dr. may write DS on an Rx in the Cylinder (CYL) field if no astigmatism correction is needed.

DV: distance vision.

FT: flat-top bifocal.

NV: near vision.

NV-ADD (also ADD): the Near Vision (NV) Reading ADDition correction on a multifocal Rx. Can be used for bifocal or progressive glasses, or for single-vision reading or computer (intermediate) vision glasses.

OD: Latin for Oculus Dexter, meaning the right eye.

OS: Latin for Oculus Sinister, meaning the left eye.

OU: Latin for Oculus Uterque, meaning each eye.

PAL: Progressive Addition (or Adjustment) Lens: sometimes on a Progressive Rx an eye dr. will write two different numbers for the NV-ADD, perhaps +2.25 and +2.50, to increase the reading power in the NV-ADD for Progressive lenses.

PD (Pupillary Distance): the PD is the measurement of the distance between your pupils. This is needed for the manufacturer of the eyeglasses to know where to place the optical center on each lens, so you can see well with the glasses.

PL: Plano. Latin for "flat." If this is in the SPH section of an Rx, it means no nearsighted or farsighted correction is needed.

RX: a prescription.

SPH: the first section on an Rx. It corrects nearsighted or farsighted vision.

UV: the abbreviation of ultraviolet. UV light is invisible to the human eye, but it is UV light that gives us a sunburn, and too much exposure to it can damage the eye. All of the lenses Zenni Optical offers come with 100 percent UV protection, for free.

VA: Visual acuity: how well the eye can see. Sometimes this may be written on an Rx, with a number such as 20/20. This would indicate that with eyeglasses made to this Rx, the vision would be corrected to 20/20 vision.

Your pupillary distance (PD) is the measurement of the distance between your pupils. Click here to learn more.

Most people have an astigmatism. If you have an astigmatism on your Rx, we can make glasses that will correct it.

Yes! We offer both. If you have ADD or NV-ADD on your Rx, you can get lined bifocals or unlined progressive glasses.

Our high-definition premium progressives feature wider viewing areas for the intermediate and reading areas of the lens than standard progressives. Peripheral (side) distortion is reduced by up to 40% compared to the standard design. With premium progressives, the transition from distance viewing to looking at a computer, for example, to reading up close is more seamless, making adaptation easier and more comfortable.

Anyone looking for an everyday pair of progressives with enhanced vision and minimal distortion. If you already have a pair of Zenni’s standard progressives, you’ll love premium progressives for improved comfort and visibility. They’re also highly recommended for anyone who is a first-time progressives wearer, since they offer an easier adaptation process.

• Fully customized, German-engineered optical lens
• Sharper focus reduces eye strain
• Easy adaptation between viewing areas
• Less peripheral distortion
• Wider intermediate and near/reading viewing areas provide maximum comfort

Ordering single vision distance glasses through Zenni is easy! Once you have selected a frame, click “Order Glasses” and follow the below steps:

1. First, indicate that you would like distance glasses by selecting “Single Vision” from the Prescription Type dropdown.

2. Next, you’ll need to input a Single or Dual PD (pupillary distance) under the Pupillary Distance dropdown. Check your prescription to see if your doctor measured it and wrote it down. If not, you’ll need to measure it yourself. You can learn more here.

3. The last step is to enter the distance prescription for the right eye(OD) and left eye(OS). Most glasses prescriptions are considered distance single vision unless your doctor noted it was for reading or computer.

Ordering reading glasses through Zenni is easy! Once you have selected a frame, click “Order Glasses” and follow the below steps:

1. First, indicate that you would like reading glasses by selecting “Single vision” from the Prescription Type drop-down.

2. Next, you’ll need to input a Near Single or Dual PD (pupillary distance) under the Pupillary Distance dropdown. For a Single PD, if you were only given one PD measurement, it is most likely for distance so you will need to subtract 3 to calculate your near single PD. If you were given a dual PD, two numbers - one for the right and left eye, you’ll need to subtract 1.5mm from each number to calculate the near dual PD. Ex. If given PD= 63mm then Near PD= 60mm.

3. The last step is to enter the reading prescription for the right eye and left eye. If your doctor didn’t write out a separate reading prescription then you’ll need to calculate it yourself. You can do this by adding the ADD value to the SPH value and keeping the remaining values the same, as in the example below:

For more information about reading glasses, check out our Zenni Blog.

If you know what strength of readers (similar to over-the-counter readers) works best for you, it's easy to turn any pair of Zenni glasses into readers!

To order Readers:

1. Once you find a fabulous frame, click "Select Lenses" to start your checkout.
2. Under Prescription Type drop-down, pick "Single Vision".
3. Enter in your reading PD, pupillary distance, or measure it like this.
4. If you know what reader power you need, for example, +1.00, +2.50 ,etc. then enter the same power for both right and left eye in the box labeled SPH. These two boxes will be the only values you need to enter.
5. Click "Submit your Prescription" and proceed to choosing your preferred lens options such as Blokz® (blue light blocking lenses) to provide more comfort when using screens.
6. Check-out and wait to receive your new pair of readers!

You bet you can! Divide the NV-ADD in half. Add one of the halves to your SPHs. Leave the other half in the NV-ADD. This creates computer vision in the top of your lens, and reading vision in the bottom!

Yes, we can fill prescriptions with prism correction in single-vision lenses only. You will enter in the values for each eye in Step 1 of the order process according to the script given by your doctor. After you fill in Sphere (SPH), Cylinder (CYL), and Axis numbers for each eye, you will click “Yes” under Prism Values. You will then select your Prism Horizontal (for Base In/Base Out) and Prism Vertical (for Base Up/Base Down) values in diopters and indicate the direction for each value on your prescription for each eye.

To learn more about prism corrections, click here.

Sorry, a contact lens Rx can only be used for contact lenses.

It's super easy to order Non-Rx glasses from Zenni Optical. After clicking on the Order glasses button, select Non-Prescription in the Prescription Type drop-down window. During the ordering process, you can turn them into sunglasses, or choose our Blokz® lenses, that protect against blue light.

We strongly recommended that you get an eye exam every two years, or more frequently if you notice that your vision has changed.

Most of the frames on our website can be ordered as sunglasses, except for some sports or goggle frames.

Premium sunglasses are only offered in four lens index options (1.53, 1.57, 1.61 & 1.67), whereas regular frames with tinted lenses are available in 1.50, 1.53, 1.57, 1.61, and 1.67.

Yes! With a few exceptions, the Rx glasses you order on our website can be turned into Rx sunglasses. Just select a standard or gradient lens tint, or choose from our glare-reducing polarized lens selections.

Photochromic lenses automatically darken when outdoors or exposed to UV rays. They return to clear when you are back indoors. Polarized lenses are permanent sunglasses that don't change color and are great at cutting glare.

Sure! If you order Rx sunglasses, you can get the lens with the index that is recommended for your Rx to keep your lenses nice, light and thin. If you get non-Rx sunglasses, your lenses will be thin.

We offer 3 sunglass tints: Dark Gray, Dark Amber, and Dark Green.

Mirrored lenses are created with a highly reflective coating that reduces glare by reflecting light away. These sunglass lenses are highly functional yet also fashionable.

Zenni offers 8 different mirror colors: Silver, Gold, Rose Gold, Flame Red, Lavender, Indigo Blue, Sky Blue, and Moss Green.

Clip-On can be ordered for most of our eyeglasses. You can check availability by visiting https://ca.zennioptical.com/clip-on-finder

If you look at LED screens through your polarized lenses, especially in bright sunlight, you might experience a ‘pinching’ effect, where certain areas of your lenses do not appear to uniformly filter light. However, this is a common phenomenon for prescription polarized lenses and not a problem with the coating application or lens quality. It should not affect the wearer’s ability to see clearly through the lens when not looking at screens. Polycarbonate is more susceptible to this effect. However, for whichever lens material you choose, this effect should gradually disappear the more you wear your glasses.

Polarized lenses reduce glare for improved clarity. They are ideal for people who spend lots of time driving or outdoors, especially for golfing, fishing, boating, or activities in a snowy environment.

The Lens Index number (1.50, 1.57, 1.53, 1.59, 1.61, 1.67, or 1.74) refers to the degree of refraction the lens provides. This means how much the light that enters the lens is refracted (bent) as it passes through the lens. Lens Index is also related to the thickness of the lens. The higher the index, the thinner the lens will be. Learn more here about what index is best suited for your Rx, lifestyle, and frame selection.

The lens that is preselected as a recommended option in ② Your Lenses during the ordering process will be the best option for your Rx. If you have a strong Rx, a higher lens index number will give you a thinner lens.

We offer aspheric lenses for our standard 1.67 high index lens, Blokz 1.67 high index lenses, Blokz tinted 1.61 high index lens, Blokz tinted 1.67 high index lens, Blokz photochromic 1.61 high index lens, and Blokz photochromic 1.67 high index lens.

Aspheric lenses are provided for the lenses listed above in this range: Sph 0 to -10.00, Cyl -2.00 to +2.00

The aspheric lens surface improves visual quality and reduces distortion of the wearer’s eyes as seen by others.

All Zenni Optical eyeglasses come with Anti-Scratch Coating and UV Protection Coating that are both absolutely free. We also offer Anti-Reflective (also known as Anti-Glare) Coatings, which reduce reflection on the lenses and the glare you see while you are wearing your glasses.

Our anti-reflective coating options include: standard, water-resistant, oil-resistant, and anti-fog.
Anti-reflective coating is applied to both sides of the lenses for most glasses and on the backside of the lenses for premium sunglasses.

Glasses fog up when you move from hot to cold environments, wear a mask or helmet, engage in outdoor activities or chores such as cooking.

Anyone who experiences foggy lenses can benefit from adding anti-fog coating to their glasses order.

Zenni’s anti-fog + anti-reflective coating reduces glare and helps prevent your lenses from fogging up. The anti-fog coating is on both sides of the lenses for most glasses and on the backside of the lenses for premium sunglasses. Each pair of anti-fog coated lenses comes with a special anti-fog activator lens cloth that activates the anti-fog properties every time you clean your lenses to help keep them extra clear.

Photochromic lenses are specially treated to turn dark when exposed to UV light. When the lenses are out of the sunlight, they become clear again. We carry the Transitions® brand of photochromic lenses for our 1.50, 1.61, and 1.67 lenses, for both single-vision and progressive glasses.

A Polarized lens is a sunglass lens that greatly reduces the glare from light that is Polarized horizontally, meaning the light reflecting off horizontal surfaces, such as a white sidewalk, a white-sand beach, snow, or sunlight reflecting on water.

Polycarbonate lenses are impact resistant, and are stronger and more lightweight than standard lenses, which makes them a great option for kids’, rimless, and sports glasses, or for anyone who is rough on their glasses.

Trivex® lenses are impact-resistant, and are stronger and more lightweight than standard lenses, which make them a great option for kids’, rimless, and sports glasses, or for anyone who is rough on their glasses. Compared with polycarbonate lenses, Trivex® is a premium material that provides crisper vision and is 10% lighter.

Trivex is a registered trademark of PPG Industries Ohio, Inc.

Do you want a tint to make your glasses into dark sunglasses?
- We offer 3 sunglass tints: Dark Gray, Dark Amber, and Dark Green.

Do you want a tint that is darker at the top, and gradually gets lighter towards the bottom?
- We offer gradient tints in Gray, Amber, Green, Blue, Purple, and Pink.

Do you want a tint that is lighter, or more colorful to enhance the appearance of your everyday glasses?
- We offer fashion tints in Gray, Amber, Green, Blue, Fuchsia, Lavender, Orange, Rose, Yellow and Red.

After selecting your frame and lens material you can add your favorite tint from 3 categories listed above – Sunglass, Gradient or Fashion Tints.

Our sunglasses tints - dark amber, dark grey, and dark green are 80% darkness. Our gradient tints start with 80% darkness on the top of the lens with an even gradation to 10% darkness at the bottom of the lens. Our fashion tints come in various levels of 10-50% darkness.

Polarized lenses are known for cutting out glare and light intensity which is very noticeable when light reflects off of water, snow, and sand. Dark lens tints are known for only cutting down the intensity of light. Some instance where dark tints are beneficial over polarized lenses is if you are using a digital screen outdoors. This is because polarized lenses will darken your view of the screen. Polarized lenses are known to improve visibility with driving, especially in severe weather conditions, therefore making you a safer driver.

Mirrored lenses are created with a highly reflective coating that reduces glare by reflecting light away. These sunglass lenses are highly functional yet also fashionable.

Zenni offers 8 different mirror colors: Silver, Gold, Rose Gold, Flame Red, Lavender, Indigo Blue, Sky Blue, and Moss Green.

We offer night driving clip-ons that can easily be made for any frame except our magnetic frames. Our night driving clip-ons enhance contrast, and reduce glare from oncoming car headlights while driving at night. These clip-on lenses have a yellow color, and the included double-sided anti-reflective coating is designed to minimize glare from surrounding light. Simply add this option to your order during the check-out process for $5.95

Note: The clip-ons are cut slightly larger than the optical lenses to provide full coverage.

Your Rx, your PD, and a frame you have selected on our website.

New glasses often need minor tweaks to fit your face right. It’s best to have an optician fine-tune the glasses for you, but you can also make adjustments yourself with our How to Adjust Your Glasses guide.

New glasses may leave you feeling a bit off-balance, so gradually increase your wear time until you fully adapt. Avoid switching back and forth between glasses, as it will take longer to adapt. It can take a few days to adapt to single-vision lenses and 2-3 weeks for progressive or bifocal lenses. If you’re still having vision issues after the adaptation period, consult your eye doctor.

We're all guilty of quickly rubbing our glasses on our shirts or using paper towels to clean the lens. While these habits may seem harmless, they ultimately can end up damaging your frames.

• Don’t use your shirt (or clothing in general) to clean your glasses. The dust and debris on fabrics can scratch your lenses.
• Don’t use paper towels or tissues to clean your glasses. These materials are too rough for your lenses and can cause small scratches. Dish towels or other fabrics that can trap dust and debris may also scratch the lenses.
• Avoid using household cleaning products to clean your lenses. Cleaning products usually contain harsh ammonia-based chemicals that can destroy the protective coating on your lenses.
• Don’t leave your glasses out on the bathroom counter when getting ready. Hairspray and beauty products can get on your lenses and damage the protective coating.
• Never try to buff out a scratch. Attempting to buff your lenses will only result in more scratches and damage. Take your glasses to a professional if you have a scratch that need to be removed.
• Don’t leave your glasses in the car on a hot or cold day. Extreme heat or cold can damage lens coatings and also may change the frame shape.
