Overexposure to which harmful light ray may cause permanent eye damage in the form of cataracts?

The correct response centers around ultraviolet (UV) light as the primary concern for human eye health, particularly in relation to cataract formation. Ultraviolet rays are part of the electromagnetic spectrum emitted by the sun and are known for their ability to cause biological damage, particularly in the eyes. Prolonged or intense exposure to UV rays can lead to changes in the lens of the eye, resulting in cataracts, which cloud the lens and impair vision.

Cataracts develop when the proteins in the lens of the eye start to break down due to UV exposure, leading to an increased opacity of the lens. This process can continue over time and potentially lead to significant vision impairment if left untreated. Protective measures, such as wearing UV-blocking sunglasses or helmets with face shields, are important for individuals working in environments where they might be exposed to intense UV light.

The other forms of light mentioned, such as laser, infrared, and X-ray, do have their own risks and health concerns. However, they do not commonly cause cataracts in the same way UV rays do. Laser light can cause damage to the retina and other parts of the eye, while infrared radiation primarily generates heat and may contribute to discomfort rather than cataract formation. X-rays, on
