I’m around screens most of the time, which does make my eyes tired. This is known as digital eye strain and it might be due to the light from your screen, including Blue Light which you’ve probably heard is supposed to be bad for your eyes. A popular way to prevent blue light from getting into your eyes is by using blue blocking or blue filter glasses. This seems like a brilliant idea, except that studies have shown that it probably doesn’t work.
A study from 2019 looked at what would happen if you block 99% of the wavelengths that compose blue light, and researchers observed no effect on eye strain. Now this is probably not the final nail in the coffin, but it suggests that blue filter glasses are probably not having the marketed effect.
The eye strain you’re experiencing likely comes from the fact that you aren’t blinking as frequently, and not as much from the blue light itself. So while more research is needed, taking a quick screen break might actually be a more effective solution.
