I bought the glasses for my husband, and he wears almost every day, while watching TV or reading. It's amazing, but after about 2 months he started to see better! So even without this and other glasses! That's really awesome. Instead of making his eyes kapputt with glasses, so everyone should buy a pair of glasses, and after about one year it could be that he / she needs more garkeine glasses because their eyes have been so well trained in the correct focus. And not just for the elderly!
