Quick Verdict: Felix Gray Nash is a premium medium-fit frame for men who want stylish computer glasses that can be worn throughout the workday. The optical-grade lenses, double-sided anti-reflective coating, hydrophobic treatment, acetate frame, prescription options, and polished design are the real strengths. However, buyers should not assume that blue-light filtering is proven to prevent digital eye strain, protect the eyes, or improve sleep. Independent evidence remains uncertain, and much of the benefit may come from glare control, an accurate prescription, comfortable fit, screen breaks, and better nighttime habits.
PVL Rating: 3.9/5
Best For: men who like a refined square-rectangular frame, need a medium fit, spend long hours on screens, and value lens quality and style more than finding the lowest price.

What Are Felix Gray Nash Glasses?
Nash is one of Felix Gray’s classic blue-light eyewear designs. Its shape sits between a traditional rectangle and a modern square, with a subtle keyhole bridge and a medium overall fit. Although the frame is marketed as unisex, the understated shape and range of neutral colors make it a natural option for men seeking office-friendly blue light glasses.
The current manufacturer listing offers black, tortoise-inspired, green, blue, and fade finishes. Lens configurations include non-prescription plano lenses, readers, single-vision prescriptions, and progressive prescriptions. Clear lenses are intended for everyday wear, while amber lenses add a visible tint for evening use.
Fit, Measurements, and Comfort
Felix Gray lists the Nash as a medium frame measuring approximately 49 mm across each lens, 17 mm at the bridge, and 140 mm along the temple. The total frame width is about 135 mm. Those numbers matter more than the “men” label: compare them with a pair you already wear comfortably before ordering.
The acetate construction gives Nash a more substantial, polished appearance than ultra-light metal or inexpensive plastic frames. That can feel reassuring and durable, but people sensitive to pressure at the nose or temples may prefer a lighter design. Comfort is highly individual, so the return policy is valuable when buying online.
Lens Quality and Glare Control
The most practical feature is the double-sided anti-reflective treatment. Reflections from overhead lights, windows, and screens can be distracting, especially during video calls or long work sessions. An anti-reflective lens can improve visual comfort and appearance even if blue-light filtration itself provides no measurable benefit.
The lenses also receive a hydrophobic treatment intended to resist smudges and moisture. That does not make them maintenance-free: fingerprints still need a microfiber cloth and an appropriate lens cleaner. Avoid abrasive paper products and harsh household cleaners that can damage coatings.
Do Blue Light Glasses for Men Reduce Eye Strain?
Felix Gray promotes its lenses for eye comfort, focus, and reduced screen-related symptoms. Those are manufacturer claims, not conclusions that can be applied to every wearer. The 2023 Cochrane review included 17 randomized trials with 619 adults and found that blue-light-filtering lenses may provide no short-term advantage for computer-related visual fatigue compared with ordinary lenses. Effects on sleep were unclear, and evidence for retinal protection was unavailable.
The American Academy of Ophthalmology has likewise stated that computer-screen light has not been shown to damage the eyes and does not recommend special eyewear solely for computer use. Digital eye strain is commonly connected with prolonged near focus, reduced blinking, dry eyes, glare, posture, screen distance, and an outdated prescription—not simply blue wavelengths.
This does not mean nobody will like Nash. A wearer may appreciate the frame, anti-reflective coating, correct prescription, or amber tint. The honest conclusion is that any improvement should be treated as personal experience rather than proof that blue-light filtration was the cause.
Clear vs Amber Lenses
Clear lenses
Clear lenses are the more versatile choice for work, meetings, driving in appropriate conditions, and all-day wear because they preserve a natural-looking view. Felix Gray says they filter selected wavelengths without obvious color distortion. They are the sensible choice if appearance and everyday usability are the priorities.
Amber lenses
Amber lenses filter more short-wavelength light but visibly alter colors. They make more sense for late-evening use than design work, photo editing, or any task requiring accurate color judgment. Even then, evidence that blue-light glasses improve sleep remains mixed. Reducing screen brightness, using night mode, dimming the room, and ending stimulating screen activity before bed are lower-cost measures.
Style for Men
Nash avoids the oversized gaming-glasses look. Its clean front, modest keyhole bridge, and conventional temple shape work with business, smart-casual, and home-office clothing. Black is the safest professional option, while Whiskey Tortoise and the deeper colors add personality without looking theatrical.
Face shape is less important than measurements and preference, but the softly squared design can add definition to rounder faces while remaining restrained on oval faces. Men with wide heads should compare the 135 mm total width carefully, because “medium” may feel narrow. Those with smaller faces may find the acetate front visually heavier than a thin metal frame.
Pros and Cons
Pros
- Polished acetate frame suitable for professional settings.
- Medium measurements work for many average-width faces.
- Double-sided anti-reflective coating is practically useful.
- Clear and amber lens options.
- Non-prescription, reader, single-vision, and progressive configurations.
- Hard case and cleaning cloth included.
Cons
- Premium price compared with ordinary computer glasses.
- Independent evidence does not establish short-term eye-strain relief from blue-light filtering.
- Sleep benefits remain uncertain.
- Amber lenses distort color.
- Medium frame may not fit particularly wide or narrow faces.
- Acetate can feel heavier than thin metal alternatives.
Who Should Buy Felix Gray Nash?
Consider Nash if you already need glasses or want a polished non-prescription frame, like the 49-17-140 proportions, and value anti-reflective lenses and acetate construction. It is particularly suited to office workers, remote professionals, students, and men who want one discreet frame rather than conspicuous gaming eyewear.
Who Should Avoid It?
Skip it if your primary goal is a guaranteed cure for headaches, dry eyes, blurred vision, or poor sleep. Persistent symptoms deserve an eye examination because an incorrect prescription, dry-eye disease, binocular-vision issue, migraine, medication, or another condition may be involved. Budget-focused shoppers and users who only want a night tint can also find less expensive alternatives.
Better Ways to Manage Digital Eye Strain
- Use regular distance-viewing breaks, such as the 20-20-20 approach.
- Blink deliberately and address persistent dryness with an eye-care professional.
- Keep the screen about an arm’s length away and slightly below eye level.
- Reduce reflections and match screen brightness to the room.
- Increase text size rather than leaning toward the display.
- Confirm that your prescription is current.
- Reduce bright, stimulating screen use before bedtime.

Alternatives to Consider
| Option | Best for | Tradeoff |
|---|---|---|
| Felix Gray Nash clear | Professional all-day appearance | Premium price; filtering benefit uncertain |
| Felix Gray Nash amber | Evening wear with stronger visible filtering | Color distortion |
| Standard anti-reflective prescription glasses | Correcting vision and reducing reflections | No special blue-light marketing |
| Device night mode plus screen breaks | Low-cost habit change | Requires consistent use |
Are Felix Gray Nash Blue Light Glasses Worth It?
Nash can be worth the price when judged as premium eyewear: attractive acetate, useful anti-reflective treatment, several prescription options, and a versatile medium fit. It is harder to justify if the purchase depends entirely on promises about preventing eye damage, eliminating digital eye strain, or improving sleep.
Our 3.9/5 score reflects that split. The physical product and styling are appealing, while the clinical evidence behind the category’s biggest health claims remains weak or inconclusive. Buy for fit, prescription, glare control, and design; treat blue-light benefits as uncertain.
Frequently Asked Questions
Are Felix Gray Nash glasses made for men?
Nash is a unisex design, but its restrained square-rectangular shape and neutral color options make it well suited to many men. Measurements matter more than gender labeling.
What size are Felix Gray Nash glasses?
The current Nash frame is listed as a medium fit at approximately 49-17-140 mm with a total width near 135 mm. Compare those numbers with comfortable glasses you already own.
Do Felix Gray glasses reduce digital eye strain?
Some customers may feel more comfortable, but independent evidence does not show a clear short-term advantage from blue-light filtering compared with standard lenses. Anti-reflective coating, fit, prescription, and screen habits may matter more.
Can blue light glasses protect my eyes from screens?
Computer screens have not been shown to emit light at levels that damage the eyes, and ophthalmology guidance does not recommend special eyewear for screen protection alone.
Can Felix Gray Nash glasses improve sleep?
Felix Gray promotes evening benefits, especially with amber lenses, but the Cochrane review found sleep evidence unclear. Limiting bright screens and using dimmer evening lighting remain important.
Should I choose clear or amber lenses?
Choose clear for work and everyday appearance. Choose amber mainly for evening use if you accept visible color changes and understand that sleep benefits are not guaranteed.
Are prescription Nash glasses available?
Felix Gray lists non-prescription, reader, single-vision, and progressive options. Availability and pricing can vary by lens material and prescription.
What should I do if screen headaches continue?
Arrange an eye examination rather than relying only on blue-light glasses. Persistent headaches or visual symptoms may have several causes and require individualized assessment.
Final Verdict
Felix Gray Nash is one of the better-looking blue light glasses for men who want medium-fit, office-ready eyewear. Its frame quality, lens choices, and anti-reflective treatment are credible reasons to consider it. Its marketing should still be read cautiously: evidence does not confirm that blue-light filtering itself prevents screen eye strain or reliably improves sleep. With realistic expectations, Nash is a stylish premium frame—not a medical solution.
