• UV is divided into three ranges: UV-A, UV-B and UV-C. UV-C, the range below 280 nm. Is not considered a threat because most of it is filtered by the earth’s protective ozone layer.
• High exposure to UV-A and UV-B rays can cause significant eye damage, ranging from temporary discomfort to long-term vision problems such as cataracts.
