When I recently shopped for new eyeglasses, the optician noticed two skull indentations (nearly 1/8" deep) along the sides of my face starting from the first point of contact (just behind the eyes) all the way up to the ears which I wasn't paying attention to in the past. He stated that they were caused by the very tight eyeglasses I had been wearing for the last two years. My new eyeglasses now properly fit against my face; but I'm concerned that the indentations might stay there since the new eyeglasses would tend to slide into them. Is there a way I could get rid of these indentations for good, or would they disappear with time? By the way, I use thin glasses and a light frame. Thanks.
