How many degrees of myopia do I need to wear glasses?

Students are the most nearsighted because they need to read and study every day. Many people have myopia during their student days. During the physical examination, everyone will check their eyesight first. Generally speaking, if the visual acuity is lower than 0.6, it means that you may be near-sighted to 0 degrees. At this time, you need to go for optometry to see the specific vision situation and see if you need to wear glasses. If the visual acuity tested exceeds 200 degrees, you must wear glasses at this time. If you do not wear glasses, your vision will be greatly affected, and the degree of myopia will rise quickly. For this reason, you must wear glasses in time to correct your vision. If the degree of myopia does not exceed 0 degrees, this is pseudo-myopia and does not require glasses. However, you should always take care to protect your eyes, avoid staring at things at close range for a long time, and don't let your eyes get too tired, so your vision will slowly return to normal.



What Do Pinhole Glasses Do?

Pinhole glasses are often used by eye doctors who use them as a diagnostic tool to quickly check for vision impairments. Of course, pinhole glasses are sometimes used to treat nearsightedness or astigmatism. Pinhole glasses are also used in conjunction with an occluder, an instrument used to cover one of your eyes while you read an eye chart. The occluder is solid, while the pinhole glasses have a number of tiny pinholes. So, the doctor often uses it to check the potential of your vision.

Pinhole glasses are often used to check corneal distortion and cataracts. A cataract evaluation includes focusing light in the eye to check if vision capability behind the cataract makes it worth performing surgery.
