I have a pair of prescription reading glasses; but I rarely use them.
I have 3 pairs of sunglasses; different styles depending on what I'd doing during the day. I have a cataract, either caused by trauma or radiation (sunshine or x-rays), in my right eye. Sunlight causes glare for me, and may make my cataract worse, so I wear good sunglasses whenever I'm outside during daylight.
Total: 4 pairs....
