These metal-plastic polarized BeOne unisex aviator sunglasses are shades that you need to protect if you want them to last a long time. The damage that sunglasses endure is tremendous. It accumulates over time to the point where the sunglasses in question are almost unrecognizable. You have to invest in some sort of protection mechanism that will minimize this damage. A soft case will protect sunglasses against scratches, which are the most common thing that happens to shades. You might want to look into hard cases if you want to protect sunglasses against not only scratches, but other forms of damage.
