-• The epithelial cells of the cornea absorb radiation in the actinic portion of the UV spectrum (200 – 315 nm). This exposure produces symptoms known as photokeratitis, which are not felt until several hours after the exposure.  Photokeratitis is very painful and produces the sensation of having sand in your eye.  It also causes an aversion to bright light, as well as the production of tears. The effects typically last up to 48 hours but will disappear as the cells of the cornea are replaced. Long-term effects can also occur.  Most of  the UV radiation that enters the eye is absorbed in the cornea, but UVA absorption by the lens can alter proteins in the lens and result in cataract formation.\\ +• The epithelial cells of the cornea absorb radiation in the actinic portion of the UV spectrum (200 – 315 nm).

-• Excessive UV exposure in the actinic range (200-315 nm) produces symptoms that are comparable to sunburn and includes redness, swelling, pain, blistering, and peeling of the skin.Factors that can affect skin response to UV include your degree of skin pigmentation and photosensitization by certain foods (e.g., figs, limes, parsnips and celery root) and drugs (e.g. tetracycline).You will recover from short-term skin damage, but chronic exposure to UV may increase your risk of skin cancer.\\ +• Excessive UV exposure in the actinic range (200-315 nm) produces symptoms that are comparable to sunburn and includes redness, swelling, pain, blistering, and peeling of the skin.

-• Protective Clothing: Wear a fully buttoned lab coat, long pants and closed toe shoes. Make sure that ALLskin is protected, including face, neck, hands and arms.  Make sure there are no gaps in your protective clothing, especially at the wrist and neck areas. Gloves: Wear disposable latex or nitrile gloves to protect exposed skin on the hands. Do not use vinyl gloves, which can transmit significant amounts of actinic UV.  Eye/Face Protection: Always wear a full face shield. To protect the eyes and face, use a polycarbonate face shield stamped with the ANSI Z87.1-1989 UV certification.  See the next slides for more information about face shield use.  Note:  if you’re working with splash or projectile hazards, you may also need to wear safety glasses or goggles under the face shield.\\+• Protective Clothing: Wear a fully buttoned lab coat, long pants and closed toe shoes.
