Explanation:

Ultraviolet rays are a type of electromagnetic radiation. Excessive exposure to ultraviolet rays (especially UV - B and UV - C) can cause damage to living tissues. Skin cancer (such as melanoma, basal cell carcinoma, and squamous cell carcinoma) is associated with long - term exposure to UV rays as they can damage the DNA in skin cells. Cataracts (a clouding of the eye's lens) can also be caused by UV radiation as it can damage the proteins in the lens over time. Sinus and throat infections are usually caused by pathogens (such as bacteria and viruses) rather than UV rays. UV rays do not improve skin or eye sight; instead, they cause harm.

Answer:

skin cancer and cataracts (eye damage).
