Best blue light glasses

Start with the PRIMALS pair. It's the only one here that states how much it blocks — 99.9% of blue light — and it has the strongest review record by far (5 of 5 from 810 ratings). The red-tinted lens is the trade-off: great for evening screen time, noticeable in daylight.

Who the others suit:

• Gunnar Intercept — gamers and long sessions; a proper gaming-glasses frame, and the cheapest way into the Gunnar line.
• Horus X — same idea, a wider 140 mm frame that sits better on larger faces.
• Rirool 2-pack — households or anyone who wants a spare pair in a bag; the most-reviewed budget option.
• SOJOS Retro Oval — a lighter, more everyday look for smaller faces.
• Vyzia clip-on — if you already wear prescription glasses and don't want a second pair.

Two things worth knowing: most budget pairs don't publish a blocking percentage, so treat "blocks blue light" as a claim rather than a spec, and tinted lenses (like the PRIMALS red) shift colours — fine for evening, less so for colour-accurate work.
