Final answer:
Klieg eyes, a condition caused by UV light exposure, can be prevented with plastic sunglasses that effectively block UV rays. Sunglasses help prevent not only klieg eyes but also cataracts, which are a widespread cause of vision loss.
Step-by-step explanation:
The medical condition klieg eyes, which is caused by overexposure to intense ultraviolet (UV) light, can be prevented by protecting your eyes with appropriate eyewear. Using plastic sunglasses can offer effective eye protection from UV light. This is important because repeated exposure to UV-B rays can contribute not just to klieg eyes but also to the formation of cataracts, a significant cause of vision impairment and blindness, especially in areas with limited medical treatment.
To maintain overall eye health and prevent conditions like klieg eyes and cataracts, it's essential to utilize sunglasses that block UV rays effectively. Additionally, people who are at risk for eye conditions due to genetic factors, such as those with Lowe disease which is characterized by cataracts at birth, should also take preventative measures to shield their eyes from damaging UV exposure.
