I went to the optometrist this morning. For a routine assessment, he had to make my pupils dilate as much as possible. This had the side effect of letting in too much light (as expected), but as well as highly distort my view with prescription glass on. Here's a simulation using a screenshot of ETar, an Android Calendar client. Regular vision was blurry as well, but any screen was 10x worse! I had issues reading even with accessibility zoom all the way up! Crazy!
