- Better sleep -
In the same way a walk outside in the sunlight can help you feel alert; spending time on a screen before bed can also make you feel alert. Short wavelengths delay release of melatonin, a sleep-inducing hormone that naturally starts releasing into your system a couple of hours before bedtime.
Using a tablet or other type of screen before bed can delay this release, making it harder to fall asleep right away. If you’re unable to turn off your device an hour or two before bed, as sleep experts recommend, using blue light glasses may help you sleep better.
- Less eye strain -
Looking at a screen all day can make you feel stressed, or you may experience eye and muscle strain. Ergonomic adjustments can help reduce the muscle issues associated with sitting at a desk and looking at a screen all day. Blue light blocking glasses can help reduce eye strain.
Blue light can make it difficult to focus on the screen, making your eyes strain to concentrate. Blue light glasses help increase contrast on your screen, making it easier to focus and subsequently reduce eye strain.
- Fewer headaches -
Light, especially blue light, can trigger migraines and exacerbate headache pain. Blocking blue light with special glasses may reduce migraine attacks and reduce headaches and headache pain.
- Reduced risk of eye diseases -
Your cornea and eye lens are good at blocking out harmful UV light from reaching the retina. However, they can’t block blue light. Damage to the retina can increase your risk of developing macular degeneration, which is a leading cause of blindness.
Blue light can penetrate your retina and possibly lead to macular degeneration-like symptoms and may increase your risk of developing cataracts. Wearing protection can help prevent this.
- Your device is here to stay -
You can avoid many of these issues related to blue light by stepping away from your computer, reading a book instead of watching TV, and limiting the use of your tablet and phone. If you’re not prepared to take these measures, blue light glasses can help you.
