Electronic devices emit a lot of blue light, which your eyes do a terrible job of blocking. Over time, blue light may strain your eyes and lead to macular degeneration, the leading cause of vision loss. Computer glasses that filter blue light can help reduce the amount of blue light you're exposed to, plus you don't need a prescription to wear them and they work even if you're already wearing contacts.
Promising review:"I work on a computer all day, and when I'm not on my computer I'm on my phone. Blue light is a very real threat to my eyeballs, which are already sensitive just by nature of belonging to me. I've long suffered headaches, migraines, and general ocular strain. I always prefer to wear my contacts during the day, so I didn't want to throw down some mad skrilla on a pair of prescription blue light–filtering specs... They work great, though it takes a minute for my eyes to adjust to the amber hues...My eyes are definitely happier, as is my head." —Christen Moynihan
