Vision loss can be caused by different problems in the eye:
- Presbyopia makes it hard for the lens to focus
- Cataracts make the lens cloudy
- Glaucoma damages the optic nerve
- Macular degeneration damages the macula, the part of the eye that allows you to see fine detail
- Diabetic retinopathy damages the blood vessels in the retina, the part of the eye that receives visual images and sends these images to the brain
