Tomorrow I'm seeing a specialist for contact lenses. At home i have several pair of glasses. Over the years I've developed changes in prescription and now I have a lot of old glasses. I've lost near focus which is typical for anyone in his '60s. But astigmatism keeps changing necessitating new glasses. Since PD is a brain disease and the eyes are a part of the brain, are shifting prescriptions typical? The new contacts are horribly expensive--40k!--so I'm wondering whether they're worth it.
TIA,
