  1. Although reading in dim light can make your eyes feel tired, it is not harmful.
  2. Even if you squint, ultra-violet light still gets to your eyes, damaging the cornea, lens and retina. Never watch welding without wearing the proper protection. Never look directly at an eclipse.
  3. Although using a VDT is associated with eyestrain or fatigue, it is not harmful to the eyes.

  7. There are several asymptomatic, yet treatable, eye diseases (most notably glaucoma) that can begin prior to your 40s.
  8. Safety goggles prevent many potentially blinding injuries every year. Keep goggles handy and use them!
