Here is how you detect Macular Degeneration.
1. Print the grid out. It's called an Amsler grid we use them every day at Ophthalmologists offices.
2. Place it on your fridge
3. Cover one eye
4. Stare at the dot in the center.
5. If any of the lines look wavy or have missing pieces go to an Ophthalmologist immediately! Blurry or fuzzy is OK just normal refractive error that glasses will take care of, we're looking specifically for wavy, collapsed or missing pieces.
6. Repeat with other eye.
