Does having fixed vision eliminate the need for every optometry of matching discount prescription glasses? Many people would say that my degree hasn't increased for a long time and has remained stable. I can skip optometry and just wear glasses, which saves more time.

I think there is no such thing as fixed vision, because a person's refractive parameters cannot remain constant throughout their lifetime from birth to death, and they change every year.

For example, both eyes have 100 degrees of astigmatism, and I insist on changing my eyeglass online every year. I have found that the direction and axis of my astigmatism fluctuate and change from year to year. If the parameters from the previous year are used for inspection, it is obvious that the best light performance of the lens cannot be achieved.

And everyone doesn't know that the degree of fitting varies depending on the environment in which the eyes are used. The distance between each frame and the eyes is different, and the required degree varies. For example, if you choose a frame that fits your face with a full frame, you may need to reduce the angle by 25 degrees. If you choose a frame with a high nose rest, you will need to increase the angle by 25 degrees to achieve optimal vision.

So, next time everyone goes to change their glasses, even if the degree hasn't changed much, they must review the degree again or make minor changes. Don't think this is a waste of time.

Computer optometry is not equivalent to prescription glasses. When we go for optometry, we should look for a reliable best place to buy eyeglasses instead of an expensive optometrist. Of course, a better optometrist can help us better understand the customer's eyes.
