Both Alzheimer's and Parkinson's diseases can impact on VISION. They do not impact on EYESIGHT
These condition do not affect the eye health, so do not directly affect the ability to read the letter chart or spectacle strength to read that chart (EYESIGHT). However they do impact on the ability of the brain to interpret information that the eyes send to the brain and to use that information to control and organise awareness and movement (VISION)
