Unlike vision, discount prescription glasses degree is a very objective thing and there is no subjective interference. Place your head on the refractometer and the degree measured will be exactly what it should be.

The degree reflects the "refractive power" of the eyes, in human terms, it is how many degrees of discount prescription glasses you need to wear to see clearly.

In addition, the degree does not specifically refer to myopia. Myopia, farsightedness, astigmatism, and so on can all be expressed in degrees. Of course, the higher the degree, the less healthy the eyes are.

The degree is related to many factors such as the smoothness of the eyeball surface, the size of the eyeball, the degree of eye fatigue, and the degree of aging of the eyeball structure.

For example, kids' eyeglasses near me need to have dilated pupils for optometry, and adults should also try to use their eyes as little as possible before optometry, in order to avoid eye fatigue affecting the accuracy of optometry readings.

Now, comprehensive optometry before fitting glasses has actually integrated objective optometry and the subjective feelings of the wearer. While checking the degree, the optometrist will constantly ask you which one is clearer and more comfortable. The objective degree is combined with subjective feelings to ultimately obtain a degree that satisfies you.

In addition to the visual acuity chart, there are also many tests that can evaluate visual quality, such as contrast sensitivity and aberration meters, but these are only assessments. Our own perception of clarity is the true "vision". Vision is a subjective thing.

Only by correctly understanding the difference and connection between vision and degree can one better take care of their eyes.
