UVB rays have the wave length ranges 315-280 nm. It is used in treatment for many skin disorders like vitiligo, eczema etc.
From the Related link (UVB Radiation...) below: "The UVB rays are mostly responsible for most cases of sunburn, as they are shorter than UVA rays and only reach the surface of the skin that is made up of the epidermis layer. The UVB radiation is absorbed by the stratum corneum on the epidermis surface. This stratum corneum is the dead cells layer - the visible layer of the skin. The UVA radiation is partly absorbed and blocked by the ozone layer before reaching Earth.
The UVA damage is deeper, as the UVA rays are longer than the UVB ones and reach the inner strata of the skin. They are responsible for causing the skin to lose its elasticity and wrinkling, leading to premature aging of the skin. They also can burn the skin, but at a deeper level. The UVA rays are not at all absorbed by the atmosphere and completely reach Earth.
Both UVA and UVB lead to skin cancer, whether it is malignant or benign. In the malignant type of cancer there is a tumor that appears as a consequence of abnormal proliferating skin cells. The uncontrollable growing of these cells leads to melanoma tumor forming, which in most of the cases is lethal."

∙ 14y agoThe Good:
Ultraviolet radiation (UV-A):
* cause sun tans (melanin is the color, and it is used to moderate Vitamin D production). * stimulate our bodies to make vitamin D, and other processes in other organisms
The Bad
Ultraviolet radiation (UV-B thru UV-C):
* breaks apart oxygen and ozone molecules, some of which make more ozone. * sterilizes bacteria. * causes sunburns. * can effect the human immune system and weaken it . * cause eye diseases such as cataracts and "snow blindness".
* cause various types of cancers. * decompose or damage plastics and painted surfaces Violet and more energetic light * cause VOCs and NOx to combine to make photochemical smog and tropospheric ozone

Sunlight is the primary source of vitamin D which helps us absorb calcium for stronger, healthier bones.

So don't spend much time in sunlight
How do UV rays harm us?

How does sunscreen protect against uv rays?
UNTIL RECENTLY, sunsreen protected you from UBV rays. Now, they are finally selling sunscreen that protects you from BOTH UVB AND UVA, which is also dangerous. In a related story of marketing manipulation, when you buy sunglass's BEWARE. The sticker on it will say 100% UV PROTECTION. What they don't say is that protection is from UVB ONLY! UVA rays are very damaging. According to my vision Dr. who is brilliant, wearing sunglass's with only UVB protection is WORSE than wearing no sunglasses! Here's why: with NO sunglasses, your pupil will close MORE and let less harmful rays into your eyes. When you wear UVB sunglasses, the pupil is shaded, and tricks your pupil to open wider. THEN, MORE dangerous UVA rays can enter you eyes and causeWORSE damage!!!!! Whenever you buy sunglasses, spend the extra money and buy ONLYthe ones that say "Protects against UVA & UVB rays."
