So this might be the reason my eyesight has been deteriorating lately!

Thanks to Teresa for uploading this article; it was very helpful and helped me understand the reasons behind my increasingly blurry vision over the past few years.

Recently, even with a prescription, I couldn't get a suitable pair of glasses when I went to get new ones. The difference in vision between my two eyes was too great, and conventiona

l solutions wouldn't work.

Strangely enough, one time I casually picked up an elderly person's glasses and put them on, and suddenly the world became incredibly clear.

I was puzzled as to why my expensive glasses weren't comfortable, while these seemingly random reading glasses from a market worked perfectly. ...I later found the answer in this article: Reading glasses are more suitable than bifocals or progressive lenses because they provide a wider field of vision.

Sometimes when reading, the same line of text appears as two overlapping lines, making it impossible to see anything clearly?

Sometimes, the eyes can't judge distances. If you're feeling unwell that day (like not having slept enough), and you forget to slow down when going up or down stairs, you might easily misstep or miss a step and tumble down. You can't drive if you can't judge distances.

Among Parkinson's patients, those experiencing vision problems are relatively few (this is my personal guess), so it's rarely discussed. Unfortunately, I've encountered this myself. Now, without glasses, I can't use my phone, computer, or read books; I can't even tell if the spots on my face have faded!

Fortunately, I see an ophthalmologist regularly every year and follow the doctor's instructions for maintenance, so thankfully, my condition hasn't worsened!
