  You can definitely get UV and UVB protection from sunglasses. Sunglasses are designed to protect the wearers from intense visible light, bright sunlight. What is more important, they also function to block Ultraviolet radiation (UV) and ultraviolet B-rays (UVB) that pose great threat to eye health. Some sunglasses even have ability to reflect or filter out 99-100% of UV and UVB. Sunglasses like this are labeled as "UV400".So if you need highly efficient protection, you can pay attention to the labels when you are choosing sunglasses. The sunglasses also provide comfort to your eyes when you are exposed to bright environment by blocking glare. There are many sunglasses manufacturers such as Oakley, Costa Del Mar and Polaroid Eyewear. Here are their official websites, and I hope you can find what you want: http://www.oakley.com/ ; https://www.costadelmar.com/home; http://www.polaroideyewear.com/.
