Ultraviolet rays (UV) are an invisible form of radiation found in sunlight, and over-exposure to UV light can cause significant eye damage, resulting in a loss of vision, and the possible formation of cataracts.
Phototherapy with ultraviolet A or B light waves, or a combination of both, may be used to treat older children or adolescents with mild or moderate atopic dermatitis; it is not suitable for infants or younger children.
Due to the filtering properties of the earth's atmospheric ozone layer, practically all of the ultraviolet light that reaches the earth's surface is the long-wave UVA, while the UVC is necessary to the generation of ozone.
It's a simple and scientific formula; when the melanin in your skin (your skin's natural protectant) can no longer accommodate the amount of ultraviolet rays that it is being exposed to, it will burn, plain and simple.
Indoor lighting, airborne contaminants, and ultraviolet light will all have an impact on the rate and extent of fading.Inspect used pieces by flipping upholstered cushions and viewing wooden or leather furniture from all sides.
In certain areas, the chemicals create holes that allow ultraviolet rays to make it through the atmosphere to the Earth where the radiation causes damage to plants and wildlife and increases the risk of skin cancer in humans.
Appropriate sport sunglasses minimize that adjustment time by evening out the light and providing protection from sudden changes while shielding the wearer from the damaging effects of too much ultraviolet radiation.
Look for bright fabrics that resist the effects of sunlight and chlorine; water-repellent fabrics that dry faster than ever; tightly-woven fabrics that protect the skin from harmful ultraviolet rays and much more.
Sunscreens for plants protects them from ultraviolet and infrared radiation.
We are enabled by means of it to extend materially the range of our observation, especially if the ordinary kinds of glass, which strongly absorb ultraviolet light, are avoided, and, when necessary, replaced by quartz.
