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.
Short term effects can be rashes, itchiness, dryness and sunburn.
Haha
Sun burns are short-term effects. Cancer of the skin could be long-term effects.
The aging effects of UV were not a hot topic earlier. With the ozone hole, it came into focus.
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 sources of exposure to UV radiations are many. Skin is the main entrance for UV.
Cataract.
Too much UV radiation harms the skin cells. Long term exposure over the years can cause wrinkling, discoloration, freckling, and skin cancer.
There is no predetermined rate at which UV radiation causes mutations. However, mutations are more likely if:the organism is closer to the radiation sourceThe radiation source is very strongThere is long term exposure
Too much exposure can cause skin burns and skin cancer
Prolonged exposure to ultraviolet light can have a number of effects on bacteria. For example, the exposure can lead to mutations in the bacteria's DNA or complete eradication of the bacteria, giving UV light antibacterial properties.
Ozone in the high atmosphere absorbs light in the UV wavelengths - thus protecting plants and animals (and people) down on the surface of the earth from the effects of excessive UV exposure.
