Do you have astigmatism?

I just looked it up and based off of anecdotal evidence, I think the answer is yes.

I have had glasses for nearsightedness in my left eye but it isn't bad enough for most situations. Never had an eye exam in my life.

I have astigmatism. I had the same issue with grids, certain fonts with lots of vertical lines, and other regular high contrast repeating patterns.

Got some glasses a few years ago for the first time from an optometrist, and now it doesn’t bother me anymore.

So I would recommend getting it checked out.

Thankyou for the recommendation! I'll go about scheduling that.
