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. **

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. **
