My eyes are -6.00 for both eyes. My glasses are very thick and not attractive. Are there any eyeglass lens that are less thick and much thinner.

There are a several grades of "thin" lens that look like normal lenses such as 1.61 index lenses and 1.67 index lenses. They are a bit expensive,but you will have a better appearance with them.

For the 1.61 index lenses and 1.67 index lenses, do you know the average cost for them? Do you have any idea about where can buy them at cheap prices?
