Does Parkinson's disease affect eyesight?

Has Anyone experienced PD affecting eyesight? My eyes have become extremely light sensitive. I can't stand being out on a sunny day without Sunglasses - even for a moment. Automotive headlights look like they are all set to "high". Bright lights blind me. I can read with my lamp set to a lower setting. Something I found uncomfortable before. Something has changed. I don't know if my problem is due to PD or side effects of my meds. or something else.
