I've been having some trouble with my vision. I knew I needed a new prescription, but some of the problems were unusual and worrisome, as they were some of the symptoms of glaucoma. I saw a new optometrist last week and he gave me a thorough exam. No signs of glaucoma or other pathology, so that's a relief. He changed my astigmatism correction and made me a new pair of reading glasses while I waited (5-10 minutes) and at a great price! Some of my "glaucoma" cleared right up with the new Rx. I still have some blurring, though, especially online, so I must limit my online reading until I see him again and we can, hopefully, correct that.
BTW, there's quite a bit of overlap between the symptoms of glaucoma and those of computer vision syndrome, which I suspect many of us here have.
