Swanwick Classic Day Swannies - Premium Blue Light Blocking Glasses - Virtually Clear Lens to Block Harmful Blue Light from Gaming PC, Laptop and Smartphone -(Black) Regular

Short review. If you live in the uk then these are the best blue light blocking glasses you’ll find. I have these (for work) and the orange lens ones (for evenings at home) to negate blue light from pc screens, tv screens and other fake light sources. The orange ones are amazing for sleep prep and my Ours ring data completely backs this up. These, clear ones, have stopped me needing my prescription glasses to work at a screen as (I guess) my eyes are under less strain. So if you. Only use glasses for screen use, these will probably cancel that out. I highly recommend both styles as part of a sleep optimisation arsenal.

Has really relieved the computer eye-strain. Thank you.

I bought these to relieve mental and physical tiredness work for 6 to 8 hours screen time each day everyday. My first impression was they allowed me to work longer before needing a rest and gave me more energy in the rest of the day once I was done. After 2 weeks now, if I go without wearing the glasses for 10 minutes I get an eye strain/headache pain. This wasn't the case before. I suspect it's a better idea to have blue light blocking screens over the actual monitors. Better still, monitors that have blue screen blocking as a built in feature. That way my eyes adjust to the screen. Seems my eyes are adjusting to everything through the lens of these glasses - blue light and the surrounds.

not what I was expecting for the premium price in this product category. I'd not buy them again.
