These 2-way lenses can be used as sunglasses or regular lenses depending on your needs. The sunglasses have a light tint, making them easy to wear for anyone. The regular lenses have prescription strength, so those who purchase them will need to have the lenses replaced at an optician. The original non-prescription lenses that came with the glasses have been discarded. The sunglasses do not have any prescription. Please understand that these have been used.
