Are the glasses good? Most people think of the quality of the frames and lenses, or the function of the lenses. Even if they think of optometry, they rarely think of the skills of an optometrist. Everyone knows whether the glasses are good or not, optometry dominates, and optometrist skills are indispensable.

The technical level of the optometrist directly determines the visual effect of the glasses. If the optometry is not correct, the power of the glasses is dark or light. It is not clear or dizzy, nausea, and vomiting, which will make you suffer. In addition, all optometrists should have a job certificate-optometry qualification level certificate. Within a day, a person's vision error should be within 25 degrees (the error of measuring vision is larger when you are over fatigued). Above 25 degrees, the qualifications of the optometrist or the optical shop are questionable.

Let's take a look at the process of optometry and glasses:

1. Check the dominant eye: In the process of checking the balance of the eyes, the adjustment of the eyes should be balanced. If the balance is not possible, the dominant eye should be slightly clearer.

2. Check the eye position: the myopia degree of exotropia and exotropia should be fully corrected, and the degree of hyperopia should be under-corrected; the myopia degree of implicit and esotropia should be under-corrected; the degree of hyperopia should be fully corrected.

3. Check the accommodative power: myopia with too strong accommodative power should be shallow, and the degree of hyperopia should be deep; the short-sighted power with too weak accommodative power should be deep, and the degree of hyperopia should be shallow.

4. Use a cross cylinder to approve the astigmatism axis and degree. The compliant astigmatism is easy to be shallow, but the contrarian astigmatism needs to be fully corrected.

5. Balance the eyes.

The above optometry all require the optometrist to have senior experience and skilled operation, so that the optometry data can be accurate, and the glasses can be more in line with their needs. If the optometrist's skills are not good, there may be errors in each item of data, so the light that is tested is not allowed to say, and the spectacles that come out will also cause damage to our eyes. So whether the optics are good or not, the optometrist's skills can't be ignored!
