You are right. It can be an issue in the other direction though.
People are checked after often sizeable waits looking at the same thing (their phone, the wall, outside) for a long time.
When you then start the switching lens tests, there will be a set of lens optimal for your current situation, and a different set of lens that would fit better for a long day of doing whatever you are usually doing with the glasses on.
Knowing how good a pair matches after accommodation is equally valuable, IMO.
- gowld 7y agoIt's important to only do eye tests when you are tired, so you get lenses that help you when you need them.
- mschuster91 7y agoSorry, that's bollocks if not outright dangerous advice. You always need glasses... and having wrongly spec'd glasses will induce massive stress on your eyes and brain. Please consult with a medical professional.
- phonebanshee 7y agoBut you do have to choose specifically _when_ you consult with that medical professional. Late in the afternoon after a day in front of the computer, when your eyes are tired? Or first thing in the morning when they're fresh?
- jtwaleson 7y agoThere is a big difference between farsightedness and shortsightedness. Optometrists can use eye drops that prevent accommodation for farsighted patients, or they can detect the "plateau" in good vision and take that into consideration for the prescription. No need to wait until your eyes are no longer "fresh" unless you have a really bad optometrist.
