There are many signs that can signal vision loss. For example, even with your regular glasses, you may have difficulty:
Recognizing faces of friends and relatives.
Doing things that require you to see well up close such as reading, cooking, sewing, or fixing things around the house.
Picking out and matching the color of your clothes.
Doing things at work or home because the light seems dimmer than they used to be.
Reading street and bus signs or the name of stores.
You may have low vision.
