Kb- I would like to offer another option. About ten years ago I was facing the same decision as you are now. Wearing glasses was always a problem because of weather, rain especially and even sweat caused problems. I considered everything that has been discussed. My eye doctor suggested that I may want to try contacts. At age 50 I didn't think I could had the patience to even try them. He offered to give me a pair to try for free. I'm 60 now and love my contacts, however I only wear them when fishing or hunting. I can purchase any frames or lense color I want. I have never been sorry for that decision. Talk it over with your doctor..............Al
