What the device does.
- + Clear daytime computer lens, amber evening lens, and polarized sunglasses
- + Single-vision and progressive prescription support; HSA/FSA eligible
- + Relative blocking claims (brand states "up to 15x/23x more than others"); no absolute percentage published

The trade-offs.
- + Genuinely fashion-forward frames — the least "biohacker" looking option in the category
- + Full prescription support (single-vision and progressive) with no blue-light upcharge; HSA/FSA eligible
- + Clear daytime lens plus an amber evening option and polarized sunglasses
- + 30-day returns and a 1-year warranty
- − Felix Gray targets eye strain, but the 2023 Cochrane review found blue-light lenses unlikely to reduce digital eye strain
- − Only relative blocking multipliers are published — no absolute percentage or nm range
- − Premium pricing, especially Rx and progressive lenses (~$284-359)
- − Marketed efficacy figures lack peer-reviewed citations on the site

Overview
Felix Gray (NY, founded 2016) is the style-led, prescription-friendly option in this category. Where TrueDark and Swanwick lean biohacker, Felix Gray looks like designer eyewear, supports single-vision and progressive Rx with no blue-light upcharge, and is HSA/FSA eligible. It’s primarily daytime computer glasses (clear lens), with an amber evening lens and polarized sunglasses as secondary options.
What you’re actually buying
The core product is a clear-lens computer glass aimed at screen comfort. Felix Gray publishes relative blocking claims — its clear lens “filters up to 15x more blue light than others,” amber “up to 23x more” — but no absolute percentage or wavelength range, which makes the figures hard to compare against brands like Gunnar that publish specific numbers.
The amber lens is the one positioned for evening “melatonin support.” If circadian wind-down is your goal, that’s the lens to consider; the clear daytime lens is about comfort and looks.
The evidence, honestly
This matters more for Felix Gray than for the night-lens brands, because its main pitch is daytime eye-strain relief — exactly the claim the 2023 Cochrane review (17 RCTs) found blue-light lenses unlikely to deliver. We therefore won’t repeat Felix Gray’s marketed figures (“47% increase in focus,” “3x melatonin,” “9/10 felt reduced eye strain”) as fact; the site provides no peer-reviewed citations for them. If your eyes tire at a screen, the evidence points more to break habits, blink rate and screen distance than to a lens.
These are ophthalmic eyewear, not a medical device.
Price
Non-prescription runs roughly $95-129; single-vision Rx $159-209; progressives $284-359. You’re paying a premium largely for frame design and prescription convenience.
Verdict: Not yet tested
We haven’t measured Felix Gray’s lenses, so no recommendation yet. If you want good-looking prescription computer glasses and treat the blue-light filtering as a minor bonus rather than the reason to buy, Felix Gray is a strong style pick. If your goal is evening circadian support, a dedicated amber/red night lens (Swanwick Sleep, TrueDark Twilights) is a better-targeted spend.
How we’ll assess it
If we test it, we’ll measure actual lens transmission to convert the “15x/23x” relative claims into absolute figures, and compare against brands that publish specs. See our methodology.
