Today I made a stop at Costco and visited the eye doctor inside to get some contact lenses. I’d tried getting them back in 2002 or so, but found that I didn’t really care for them at the time with my eyes feeling dry almost all the time. Now that I’ve been biking a lot I find myself wanting sunglasses, but it’s both difficult and rather expensive to get them in prescription models, and even if I do it’s necessary to carry a pair of clear lenses if I’m out late enough that it becomes dark.
This eye exam was much different than the last, with a device being used to determine how much correction my eye needs then the results of this confirmed with the old fashioned lens-based eye exam tool. This is much nicer than the old “This or That”, “One or Two”, “A or B” method. This was followed up with a puff-less glaucoma test, inspection of my retina, and then application of a fluorescent dye and close-up inspection of the surface of my eye and tears.
The device which automatically determined my prescription displayed an image of a hot air balloon with three colored stripes, which I suspect is really the image it looks for on my retina, with the three colors being used so it can compensate for chromatic aberration. It also measured my pupillary distance, which the doctor noted on the prescription after I asked for it so that I can use said prescription to order glasses online.
Hopefully I’ll have some time this weekend and throughout this week to try out the daily disposable contacts that I was given. This type was suggested to me by the doctor after I told him that I only plan on wearing them on days when I’ll be riding my bike, and that otherwise I’ll probably just wear my glasses. He told me that he uses this type as well when playing softball and is quite happy with them.
