What are plano sunglasses?

Plano sunglasses are defined as non-prescription sunglasses, meaning they do not contain any vision correction. These sunglasses are designed to block out brightness and protect the eyes from harmful UV rays while providing a comfortable visual experience without altering the user's eyesight. They are often made in frames that are compatible with prescription lenses, allowing individuals who wear corrective eyewear to wear them over their regular glasses or for those who do not require any lens correction at all.

This type of eyewear is particularly beneficial for individuals who want the aesthetic and protective features of sunglasses without needing the additional cost or weight of prescription lenses. As such, they are suitable for a wide audience, including those with perfect vision, who enjoy sunglasses primarily for fashion or sun protection purposes.
