Eye Injury From A LED Light

Published: December 01, 2015
Dear TeenHealthFX,

For a few months now, I've had bumps all over my scrotum and up my shaft, stopping just below my foreskin. I looked up genital warts, one picture looked almost identical and what I read was pretty much matching symptoms; Small, fleshy bumps in clusters that itch. They are much more apparent on my shaft when I am erect, but on my scrotum they are always apparent. Upon a closer look they look almost in a grid assortment. The thing is, I'm 13 and haven't had any type of sexual activity. At all (Anal, Vaginal, or Oral, however I do masturbate quite regularly). If these are warts, how did I acquire them without sexual activity?


Dear Eye Injury From A LED Light,

For some reason people seem to be drawn to shining lights into people’s eyes without considering the harm it could be causing. 

There is a reason that manufactures put warnings on their products. Prolonged exposure to a blue LED light that emit strong blue light wavelengths  (400-470 nanometers) have been shown in some studies to harm the retina in people who: 

  • Take photosensitizing medication such as nonsteroidal anti-inflammatory drugs (NSAIDs), most antidepressants, some antibiotics, diuretics, and beta-blockers and other heart medications;

  • Have a pre-existing ocular condition such as macular degeneration;

  • Are diabetic or otherwise at risk for retinal damage.

Those over the age of 55 blue light is the hardest for the eye to focus on. We actually see a halo around bright blue light. Blue light scatters more inside the eyeball than other colors, produces more glare, eyestrain and eye fatigue. You may have experienced some of these effects after having the light shined in your eyes. Since the amount of exposure was very limited and you most likely blinked a few times, it is extremely unlikely you suffered any permanent damage. However if you are having any difficulty seeing or are excessively worried, then it would be a good idea to see an ophthalmologist to have your vision checked out.
