Preventative Health for Eyes through proper diet and education.
Very much agree with you regarding the advantages of polarized sunglasses. Wearing prescription sunglasses may increase the cost of those glasses, but generally in my experience I find that most sunglasses are available on prescription and with the advent of the internet it has never been cheaper. I found the advice on the Vision Express website really informative when I was deciding my latest pair. You can choose lenses around your requirements for the glasses (eg skiing, water sports), secondly they have a 'try on sunglasses online' feature so you can see whether your prospective new glasses suite you.
