The fact of the matter is, our eyeballs don't get longer as we age. (Is your skull getting any longer? Nope.) In reality, your eye muscles can, just like other muscles in your body, lose their strength or fitness due to lack of exercise. The Health Ranger's Pinhole Glasses are designed to help you exercise the tiny muscles in your eyes just like other muscles in your body. We all understand the importance of exercising the other muscles in your body. Your eye muscles need exercise, too!
