8 points you need to know to wear glasses

As for optometry, some people don't pay attention to it. Some people have some misunderstandings. Today, I'd like to talk about some common sense of optometry, and I hope you can treat it scientifically and correctly.

1, glasses fitting, generally follow the principle of the best vision maximum positive mirror.

Maximum positive :

To myopic patient points to can achieve optimal eyesight namely (1.0) when the lowest myopia degree is number, when ensuring the eye sees far already so clear and bright, see close again won't overfatigue. For patients with hyperopia, it is the highest degree of hyperopia at the time of optimal vision (1.0).

2, corrected visual acuity refers to monocular corrected visual acuity, monocular corrected visual acuity has reached 1.0, binocular corrected visual acuity may be 1.2, sometimes do not need to often use the eye patients to correct visual acuity to 0.8.

3, there is a principle when matching glasses: myopia mirror rather than shallow, not deep, correct to 0.9 to 1.0 is appropriate; Farsightedness mirror should "give enough", it is how many degrees match how many degrees.

4, glasses is not corrected the higher the better, some myopia patients hope to get glasses to correct the vision of 1.5, that the higher the better, in fact, will damage the eye's regulatory function, causing visual fatigue.

5, some patients hope to correct visual acuity does not reach 1.0, afraid to see the more clearly the increase in myopic degree faster, this is also a misunderstanding, long-term will deepen the degree of myopia

7. Myopia can reach 1.0 or above through lens correction. If it does not reach 1.0 or above, there may be several problems:

Glasses are not well matched there is myopic amblyopia there is myopic fundus change there are myopia complications

The glasses don't match

Have myopic amblyopia

There are myopic fundus changes

There are nearsightedness complications

8, choose to go to a regular eye hospital with optometry glasses is very necessary.

Doctor reminds: optometry adds lens to want to choose normal hospital, minor degree grows fast, want to see a doctor in time, adult a pair of eyes is most multifunctional two years should be replaced in time.
