Best blue light blocking glasses for computer use

Top pick: Zenni Optical Blokz — it's the one I'd start with. It filters blue light up to 420 nm, adds 100% UVA/UVB protection and an anti-reflective coating, and you can order it in your own prescription. That combination is what makes it comfortable for a full workday rather than just an hour of gaming.

Who the others suit:

• Gunnar Intercept — if you game as well as work; the amber-tinted lens cuts the most blue light, but colours shift, so it's less ideal for design or colour-critical work.
• Firmoo Classic Square — if you want a light, plain clear-lens pair for reading and screen time without thinking about it.
• Somnr Gamma Ray — if you want a simple, well-reviewed everyday pair to keep at the desk.
• Hushly Computer Glasses — if you'd rather have a dedicated computer pair with strong owner ratings.

One caveat: I couldn't verify the blue-light specs for every pair here, so check the lens details on the ones that matter to you.
