Sun burns are short-term effects. Cancer of the skin could be long-term effects.
Short term effects can be rashes, itchiness, dryness and sunburn.
Well some long term effects are damaged eyes and of course skin cancer which can be fatal if you don't take care of your skin.
Ones shorter than the other
The sun's primary danger to us comes in the form of UV light or radiation. UV radiation is a component of solar radiation. Artificial sources like welding machines, tanning beds, and lasers can also give off UV radiation. There are three types of UV radiation. UV-C is absorbed by the ozone layer and does not present any threat. UV-A and UV-B radiation can have adverse long- and short-term effects on the eyes and vision. Both long- and short-term exposure to UV radiation can harm the eyes, affect vision, and compromise overall eye health. There are several eye diseases and conditions caused or aggravated by exposure to UV radiation: Macular Degeneration. Cataracts.. Pterygium. Often called "surfer's eye." Skin Cancer. Skin cancer in and around the eyelids is also linked to prolonged UV exposure. Photokeratitis. Also known as corneal sunburn or "snow blindness."
The UV rays are of three types. they are UV-A, UV-B, UV-C.
No. Long-term wearing may well reduce chances of developing eye diseases or eye problems. Consequently, failing to protect your eyes against harmful UV rays will result in adverse/egative effects.
Useful effects of UV are also there. Filters, locks etc use UV.
Of course they could. One of the most well known sources of cancer is radiation, which is energy itself (whether it be UV overexposure from the sun or gamma waves from an atomic bomb). This energy could easily be turned into a weapon, which would, as a side effect, cause cancer. Most effects from weapons are immediate, a cut from a knife, bullet hole or the loss of a limb from a mine. Long term effects might not be seen as being as 'valuable' as short term immediate effects.
Ultra violet
No. UV damage won't occur if the tires are stored in long term storage. Most likely they won't be exposed to any UV damage since they will be stored indoors.
UV rays affect vegetables. They alter their chemical composition.
