Cuts out blue light, useful as part of a photophobia desensitisation and migraines

The FL 41 lenses work well for me. I have some troubling photo-sensitivity following eye surgery and the lenses do help. Far better than wearing sunglasses as you can still see things clearly to work and to read.Some have complained that they don't give natural daylight colours. Well, I think that's the point of them: to block certain wavelengths. Things look a bit pink-ish but you get used to it. Depends on whether you want eye pain or not.However the frames are just too small and also poorly designed:1. They are not fit over for my glasses which are a bit large but I don't think these would fit over anything except small-ish specs. So they don't so much fit over as sit on my glasses leaving lots of gaps at the side and bottom but also at the top.2. The arms are really a very tight uncomfortable fit. There are little screws which, if adjusted, might help loosen them a bit. However the screws are so so so small. I have screwdrivers for my glasses but they couldn't budge these little perishers. So although my eye pain is better I now have a headache.If I could loosen the arms I'd carry on wearing them but I think I will have to get some bigger ones. Unfortunately there doesn't appear to be much choice for those of us wearing prescription glasses.

The one thing I’d say is measure your frames first before purchasing these. Mine only just fit under them. You might also need a bit of tubed foam under the legs on your ears. You can also use these as sunglasses. Really glad I bought them. Particularly for screen time before bed.
