Helpful hints

Keep these tips in mind when choosing which pair of Felix Grays would best suit you:

  1. Glasses should stay put on your nose.
  2. Don't let your eyebrows hide below or make contact with the frame.
  3. Make sure the bottom of the frame doesn't rest on your cheeks.
  4. Your pupils should be aligned near the center of your lenses.

Low nose bridge

Looking for a low nose bridge fit? Both the Nash and Faraday have our narrowest bridge at 17 mm, while the Kepler, Haro, and Hamilton frames have adjustable nose pads which helps the frame rest comfortably on your nose.

Frame malleability

We designed Felix Grays with a malleable acetate frame, allowing your pair to mold to your unique fit over time. We source our frame material from Mazzucchelli acetate producers in Italy. Our frames are made out of cellulosic acetate which is predominately a plant-based material.

If your pair gets bent-out-of-shape through regular use, gentle adjusting at the arms of the frame will get your Felix Grays back into perfect shape! You can adjust them yourself or take them to an optical provider to perfectly fit your face.

Vision insurance

Vision Insurance

While our glasses are reimbursable through vision insurance, we don't work directly with any insurance providers. If your vision plan covers prescription glasses then Felix Grays should be reimbursable. 

Felix Gray accepts FSA and HSA dollars for all prescription eyewear purchases and readers as long as your card is affiliated with a major credit card provider. However, if you’re purchasing non-prescription lenses, sleep glasses, or sunglasses, we recommend following-up with your vision care provider to confirm if (a) they cover blue-light-blocking glasses and (b) if there is a minimum magnification required for reimbursement.

If there are any issues with reimbursement, reach out to to request a more detailed invoice.

Applying for Reimbursements

Don't let your pre-tax health care expense dollars go to waste! Felix Gray glasses can be covered directly through your flexible spending account (FSA) or health savings account (HSA) since most providers reimburse for blue light blocking lenses. After purchasing, you can find your detailed invoice receipt if you log into your account, click on the relevant order number, and click on the "Invoice" button. Reach out to for any additional questions.

Prescription eyeglasses

How do I obtain a prescription?

Make an appointment with your local optical provider, optometrist, or ophthalmologist for an eye exam. Make sure to request that they include your pupillary distance (PD) with the prescription.

How do I submit my prescription?

When you've chosen your Felix Gray frames, you can upload an image of your optical prescription during checkout. Alternatively, you can choose to send us your prescription at a later date or provide us with your doctors contact information to reach out to them directly.

If you choose to email us your prescription later, you will automatically receive an email prompting you to reply with your prescription attached.

How do I measure my pupillary distance?

Your pupillary distance (PD) is the measurement in millimeters between your pupils. It allows us to locate the optical center of your lenses so the prescription is correctly placed in the glasses. If your doctor didn't include this measurement with your prescription, the following options are available to you:

- Measure your pupillary distance using our online PD tool.

- Call your doctor or optical provider to request your PD measurement.

- Visit an optical location to get your PD measured. This is either free or requires a small fee. Once you learn your PD, please email it to us at with your order number.

High Index 1.67 lenses

For all prescriptions orders, Felix Gray offers 1.67 High Index lenses free of charge. High Index lenses are thinner and lighter than Polycarbonate lenses, making them optically superior. This allows us to offer the highest quality prescription lenses to all of our customers at an affordable price.

Can you fill my prescription?

We can fill single-vision prescriptions with a spherical value (SPH) between -6.00 and +4.00 up to a -/+2.00 cylinder (CYL). If you have astigmatism, we need both your cylinder and axis values. 

We do not offer bifocals for ADD powers, prism, or progressives at the moment. We can however, accommodate your ADD value as a single vision lens for near vision/computer or distance.

If you're interested in receiving a notification when we offer additional spherical values, bifocals, progressives, and prism, feel free to sign up for our prescription mailing list.  Deciphering a prescription may be tricky. If you have any questions about whether we're able to fill yours, email with your prescription attached.



What is your return policy for Rx orders?

While all orders are limited to two prescription pairs of glasses per order, we still offer a 30-day risk-free return policy after the delivery of your order. We have free shipping, returns, and exchanges - always!

Reading and non-Rx eyeglasses

What reader magnifications are available?

In addition to our non-magnified, +.25 lenses, and prescription offerings, we also carry stock reader glasses available in +0.5, +1.0, +1.5, +2.0, and +2.5 power. If you have a reading Rx, we're able to fill any spherical value up to a +4.00 for single vision powers. Unfortunately, we do not offer bifocals at the moment.

Can anyone wear non-Rx?

Yes (with contact lenses, if needed)! All non-Rx Felix Gray glasses are currently worn by those who use contact lenses, reader magnification or do not need a prescription.

We also offer an optional +.25 magnified lens option to reduce stress on the ciliary muscle for those who are glued to their screens for hours at a time (think: analysts, designers, or coders). However, if you are glancing up, down, and around your environment/using multiple fields of vision throughout the day (taking notes, looking at multiple monitors, in meetings), unmagnified lenses may be the more comfortable way to go!




What are the key features to Felix Gray sunglasses?

Color enhancement

When Blue Light hits your eye it scatters more than any other color (fun fact: the scattering effect of Blue Light is the same reason the sky appears blue). This mutes the richness of the visual spectrum. Our sunglasses filter Blue Light, block 100% UVA/UVB, and enhance all colors to their truest form.


When light reflects off surfaces, like water, it creates an intense amount of glare. Our polarized lens filters light, reduces glare, and increases outdoor readability on digital devices for vivid accuracy.

360-degree protection

Light hits more than just the front of the lens. That’s why our superhydrophobic backside AR (anti-reflective) coating reduces indirect light from reflecting back into your eyes.

What are polarized lenses?

Light waves from the sun or light bulbs reflect in all directions, which can create an intense amount of glare. Polarized lenses help eliminate the scattering of light and only allow light to travel in one direction, which reduces glare. Our thin polarized lens increases outdoor readability on digital devices and diminishes distortion for optical clarity.

How do Felix Gray polarized lenses compare to standard tinted lenses?

Light moves in many directions and can emit vertically, horizontally, or diagonally. Tinted sunglasses decrease light intensity, but in doing so cause colors to appear dull and muted. In fact, tinted lenses don’t increase color richness or eliminate glare, and only disturb vertical and horizontal light. Felix Gray’s polarized sunglasses, on the other hand, go an extra step further. Our lenses remove glare and distortion by only allowing vertical light through the lens. Our thin polarized lenses improve optical clarity for an overall heightened visual experience.

Do Felix Gray sunglasses offer UV protection?

Yes! Our sunglasses block 100% UVA/UVB light. According to The Vision Council, the sun emits UVA, UVB, and UVC. The Earth’s atmosphere absorbs UVC rays, but UVB rays are not fully blocked and can still burn the eyes and skin. The most harmful rays (according to the World Health Organization) are UVA rays, which are not blocked by the atmosphere and are responsible for the most damage to vision health.

How should I care for my sunglasses?

We always recommend keeping your sunglasses in the Felix Gray hard case to avoid any damage. The lenses are high-quality CR-39, which is a plastic polymer commonly used when manufacturing eyeglass lenses. We developed a proprietary lens technology (that’s engineered and manufactured in the U.S.) that contains internal Blue Light filters, premium anti-reflective coatings, and 100% UV protection.

We recommend using the microfiber cloth you received with your sunglasses for cleaning any smudge, fingerprint, or dirt from the lens. Using lotion-free soap or dishwashing liquid with water works as well! We don’t recommend using chemical-based cleaning materials or fibers since they may scratch or damage the lens.

If your sunglasses accidentally get splashed with water, don’t worry! Our sunglasses can get wet, but we recommend rinsing with tap water after being exposed to saltwater or chlorine.

What is the return/exchange policy for sunglasses?

We offer a 30-day risk-free return policy after the delivery of your order with free shipping, returns, and exchanges. We encourage you to visit our Fit Guide to determine which fit is right for you. You can also email a photo of yourself to for personal stylist recommendations.

Sleep glasses

What are sleep glasses?

Our sleep glasses are a more enhanced way to specifically filter the range of Blue Light that impacts melatonin secretion (440-500 nm wavelengths) to improve the quality of your rest. Our clinically proven sleep lens acts as a natural sleep aid that minimizes color distortion despite the lens tint.

When should I wear my sleep glasses?

Put on your sleep glasses when you come home in the evening or when the sun goes down until you go to bed. The longer you wear them, the more effective they are in assisting you with a better night’s rest.

Are sleep glasses available in prescription or readers?

Felix Gray sleep glasses are available in non-prescription, prescription, and reader magnifications of +0.25, +0.5, +1.0, +1.5, +2.0, and +2.5. We can fill prescriptions with a spherical value (SPH) between +2.00 and -3.00 up to a -/+ 2.00 cylinder (CYL).

Will the sleep glasses affect my color perception?

Felix Gray sleep lenses were engineered to minimize color distortion despite the lens tint. This way, you don’t have to worry about looking through heavy amber tinted lenses that drastically affect color perception.

What material are Felix Gray sleep lenses made of?

Felix Grays sleep lenses are made out of High Impact 1.56 lenses, which is a super lightweight and impact resistant material.It has a very high Abbe value and is optically superior to polycarbonate lenses. While the lens tint is more yellow than the Felix Gray proprietary clear lens, our sleep lens specifically filters the range of Blue Light that is most disruptive to our natural sleep cycle in the 440 nm - 500 nm range.

What is the return policy for sleep glasses?

We offer a 30-day risk-free return policy after the delivery of your order! We have free shipping, returns, and exchanges. Feel free to email with any questions, concerns, or to initiate a return or exchange. 

Blue Light / glare

Blue Light exposure

Emitted by the light from our screens, Blue Light has the highest energy wavelengths on the visible light spectrum. Similar to how UV-light overexposure harms our skin, Blue-Light overexposure can lead to eye discomfort and irritation (think: eye strain, dry eyes, eye fatigue, blurred vision, and headaches). Blue  Light also suppresses melatonin secretion - the neurotransmitter that tells our minds and bodies to power off at night - which is why it is harder to fall asleep after spending hours in front of our screens every day.

That’s where we come in! Felix Gray’s virtually clear lenses are designed to filter Blue Light  - specifically, the highest energy wavelengths in the 380-440 nm range. Still interested in learning more? Head here to read on!

Glare reduction

Glare is emitted from many sources of light, including digital screens such as desktop monitors, laptop screens, phone screens, tablets, and TVs. It is a common and often overlooked culprit of Digital Eye Strain. Symptoms of DES (also known as Computer Vision Syndrome), include eye strain, dry eyes, blurred vision, and headaches.

Our lenses have a premium anti-glare coating to eliminate 99% of glare, which optimizes our visual acuity.

Glare can be a particularly distracting and straining problem at night. It’s one of the reasons looking at screens in dark settings is even harder on the eye (helpful tip: keep lights on when you’re doing work in front of your computer! By doing so, your environment is better lit and the effects of glare are less intense). Because our lenses eliminate 99% of glare, our glasses can also assist with driving at night when the glare from other cars and surrounding lights are intensified. 

Ultimately, Felix Gray’s anti-glare coating aims to provide sharper optics and relaxed eyes. We are dedicated to making people’s lives happier in front of the screen!

Negative effects of screen use

Humans are not meant to stare at digital screens (whether laptops, monitors, phones, tablets, or TVs) all day long. Our eyes are at rest when we’re looking 20 feet away. In front of our computer, though, we're staring 18-24 inches away for long periods of time. This overworks the ciliary muscle in the back of our eye, which is constantly spasming back and forth to adjust to the close viewing.

As a result, many ophthalmologists, optometrists, and researchers point to the potential negative effects that computer screens have on our vision and health. This includes Digital Eye Strain (also known as Computer Vision Syndrome) - which encompasses a variety of symptoms like dry eyes, headaches, blurred vision, eye fatigue, and neck and back pain. Felix Gray lenses are specially designed to filter 50% of all and 90% of the most impactful ranges of Blue Light, while eliminating 99% of glare to combat these negative and uncomfortable effects.

Lens technology

Why Felix Gray lenses are better

There are several blue light filtering solutions, but they’re not all created equal. Our virtually clear lenses will not distort your color perception or acuity, and will filter over 50% of all, and nearly 90% of the most impactful range of Blue Light. Additionally, our lenses have a premium anti-glare coating that eliminates 99% of glare, offer 100% UV protection, and are smudge- and scratch-resistant.

 The reason we're more effective is the way our proprietary lens filters Blue Light. We embed a naturally occurring blue light filtering ocular pigment into our lens. This makes it the perfect balance between a virtually clear and effective solution. It also has the added benefit of blocking UV rays as well! We also apply a premium AR coating, to block ~100% of glare. Blue Light and glare are two massive reasons for symptoms of Digital Eye Strain, like eye fatigue, headaches, dry eyes, and blurry vision.

We believe that Felix Gray lenses are the perfect balance between a virtually clear, beautiful lens and an effective Blue Light filtering solution. We did the research so you don’t have to! Check out our lens technology pages for additional information.

Nope, there aren't negative side effects!

Our eyes never evolved to stare at screens all day, so our Blue Light filtering lenses are only doing your eyes a favor and allowing for more comfortable and productive screen time. In fact, if you’re wearing non-magnified lenses, then you’re good to wear your Felix Grays both in and out of office settings!

However, if you decided on magnification (whether +.25 or a reader lens), then we recommend only using your glasses in close distance viewing. Regardless of magnification, though, your eyes will not become dependent on the positive effects of your Felix Grays!

Do I need magnification?

Magnification is definitely not for everyone. Most of us are in meetings or talking with a colleague intermittently throughout the day, giving our eyes temporary breaks from the screen. If this sounds like you, non-magnified lenses may be best for you.

But, if you’re glued to your screen and find yourself hunched over and squinting, then it may help. The optional +.25 magnification helps your eyes’ ciliary muscles work less when spending hours on end glued to your screen (think: coders, analysts, designers). 

The downside to the magnification is that if you interact with your environment and keep your glasses on, they could cause some otherwise unprecedented irritation and disorientation (some customers do not experience this, though). Ultimately, each person's eyes are different, which is why we offer free shipping, returns, and exchanges for the first 30 days after the delivery of your order.

Lens warranty / proper care

Keeping your lenses clean

The microfiber cloth should be sufficient for cleaning any smudges or dirt from the lenses. Using lotion-free soap/dishwashing liquid and water with a microfiber/lint-free towel works as well! 

We do NOT recommend using hot water or any chemical-based cleaners on the lenses, and be sure to NOT leave your Felix Grays in the car, on top of a heater, or in an enclosed, unvented space for extended amounts of time. Heat and chemical reactions (from alcohol-based cleaning solutions, for example) can affect the AR coating.

Hairspray can also damage the integrity of the lenses' AR coating, so we suggest taking your glasses off when applying hairspray and waiting for it to fully dry before your lenses come into contact with your hair.

Warranty Information

All Felix Gray lenses come standard with a one year warranty against manufacturing defects. The warranty includes defects in materials, workmanship, coatings, and cracks. Manufacturing defects do not include scratched lenses, normal wear and tear, improper cleaning, dislodged lenses, or exposure to excessive heat.

We offer lens non-prescription, reader, sleep, and sun lens replacements for a $50 fee. We also offer prescription lens replacements for a $100 fee, which includes the return shipping, new lenses edged into your frames, packaging, and shipping back to you. 

If you're interested in a lens replacement please email us at
