Sunglasses without UV protection are dangerous because they do not block harmful ultraviolet (UV) rays from the sun. Prolonged exposure to UV rays can lead to serious eye conditions such as cataracts, macular degeneration, and even cancer of the eye or eyelids. Wearing sunglasses without UV protection can give a false sense of security, causing people to stay out in the sun longer without proper protection, increasing their risk of eye damage. It is important to always choose sunglasses that offer 100% UV protection to safeguard your eyes from potential harm. **

Sunscreen typically protects against UV rays for about 2 hours. However, this can vary depending on factors such as the SPF level, sweating, swimming, and the amount of sunscreen applied. It is important to reapply sunscreen every 2 hours, or more frequently if you are sweating or swimming, to ensure continuous protection against UV rays. **

The UV protection of sunglasses is determined by the level of UV radiation that they block. Look for sunglasses that provide 100% UV protection, as this will ensure that they block both UVA and UVB rays. It's important to check the label or product description to confirm the level of UV protection offered by the sunglasses. If the sunglasses provide 100% UV protection, then they are considered sufficient for protecting your eyes from harmful UV rays. **

One should not apply sunscreen at night because UV rays are not present during the night. Sunscreen is designed to protect the skin from the harmful effects of UV rays, which are only present during daylight hours. Applying sunscreen at night would not provide any additional protection and may clog pores or cause skin irritation. It is important to apply sunscreen during the day when UV rays are present to protect the skin from potential damage. **
