 UV rays can cause damage to the eyes as more than 99 percent of UV radiation is absorbed by the front of the eyes. Corneal damage, cataracts, and macular degeneration are all possible chronic effects from UV exposure and could lead to blindness. Melanoma, a type of skin cancer, can also develop within the eye. It could also cause sunburns. May result in edema, pain, and peeling of the skin a few days following exposure.

Food and drug companies also usd U.V lamps to sterilize their products. Suitable doses of ultraviolet rays cause the body to provide vitamin D.]]> 2018-02-12 21:38:21 UTC https://padlet.com/ctomkinson/bdo76isrk8m7/wish/230843239 https://padlet.com/ctomkinson/bdo76isrk8m7/wish/230843254 Question by Jacob Flores,Marco Villar, Leah villasenor

Ultraviolet waves come from the sun, stars, and aurorae. Though the sun emits all of the different kinds of radiation, 99% of its rays are in the form of visible light, ultraviolet waves, and infrared waves. Man-made lamps can produce UV radiation.
