If you have a -6.00 prescription, you have extreme myopia! But your minus prescription number shouldn't mean you have to subtract a lot of cash from your bank account, or suffer with a heavy concave eyeglass lens. An aspheric high-index thin eyeglasses lens or an aspheric progressive eyeglass lens can stand up to your advanced myopia and have you singing, “I can see clearly now...I can see all obstacles in my way...”
Another choice for thinnest eyeglass lenses are polycarbonate, also known as featherweight, eyeglass lenses, which you can wear in regular eyeglass frames if you're not doing sports.
