I wear contact lenses and for the most part, I can keep my hands and lenses clean enough to wear them on extended BP trips. However, a few times now, they have gotten dirty and I had a slight eye irritation, so i had to stop wearing my lenses and use my prescription glasses instead, which are not sun glasses and my eyes got cooked. My lenses are extended wear Acuvue (the original), but I always use them as daily wear, so i'm okay to sleep in them occassionally, but not for extended periods.
So now, I would like to get a good pair of prescription sun glasses that are an athletic style & material, so that they are UL and not heavey like a regular pair that doesn't hold up to sweat and long periods of wear in athletic ativities, like BPing.
Alternatively, I could use a source that makes presription lenses for my toaster sunglasses. I've seen a few online before, but not so much lately.
Also, I need a very small frame size - I have to shop in the children's section sometimes because my ideal frame size is 45.
