Blue light glasses are designed to reduce exposure to some blue light emitted from digital screens.
Many users report greater visual comfort during prolonged screen use, although current scientific evidence does not conclusively show that blue light glasses prevent eye disease or consistently reduce digital eye strain for everyone.
What generally helps with screen comfort includes:
- Taking regular breaks (such as the 20-20-20 rule)
- Keeping screens at a comfortable brightness
- Maintaining proper viewing distance
- Correct prescription lenses
Blue light filtering lenses may still be a useful option for people who find them more comfortable during extended computer use.
