1 minute to teach you how to understand the eye test form, recommended to save it

After each eye examination

Doctors will attach the test results to the medical record.

But the characters and numbers that look like passwords

Many people said "I don't understand"

I have no idea what R, L, PD, VD are.

It's actually very simple

The information at the top of the eye test form is the date and time of the examination, the examination number and the name.

OK, now it’s time to start “decoding”——

In the form, R stands for right eye and L stands for left eye.

Therefore, the data in the column represents the data for the right eye, and the data in the column represents the data for the left eye.

The data in L.DATA is usually the final comprehensive reference value after three eye tests (due to equipment differences, some eye test forms also use SE to represent the final comprehensive reference value after three eye tests).

S stands for spherical lens, which indicates the degree of myopia or hyperopia ("+" refers to hyperopia; "-" refers to myopia), for example: +0.75 represents 75 degrees of hyperopia.

C stands for cylinder, which indicates the degree of astigmatism, for example: -0.25 represents 25 degrees of astigmatism.

A refers to the astigmatism axis, and there is an astigmatism axis only when there is astigmatism.

VD refers to the lens-to-eye distance (indicating the test distance), which is similar to the distance from the lens to the corneal apex when we usually wear glasses.

PD refers to the pupil distance, which indicates the distance between the pupil centers (the center of the black pupil) of the two eyes.

Through the above description

I believe everyone has a basic understanding of the optometry sheet.

Let’s interpret it together

According to the optometry results:

The right eye had 50 degrees of hyperopia, no astigmatism, and no axis of astigmatism;

The left eye is myopic 175 degrees, with no astigmatism and no astigmatism axis.

Eye distance: 12mm

Interpupillary distance: 60mm

I have this optometry sheet.

Can I then happily take it to get glasses?

This data is just the result of ordinary optometry

Ordinary optometry ≠ medical optometry

Ordinary optometry is generally based on computer optometry to determine the refractive power, and the operation method and steps are relatively simple. In this case, the measured degree is not particularly accurate, so some friends will experience symptoms such as dizziness and nausea when wearing new glasses.

Medical optometry is to check the convergence of light after it enters the eyeball. It uses the emmetropia state as the standard to measure the difference in convergence between the examined eye and the emmetropia eye. It is a scientific prescription given based on more than a dozen diagnostic indicators such as the patient's eye examination, refractive state, eye position, accommodation, visual function, age, occupation, eye habits, etc., which is directly related to the accuracy and comfort of the glasses. Wearing glasses after medical optometry can allow patients to see objects clearly and have a more comfortable experience.

Therefore, ordinary computer optometry in professional ophthalmology hospitals is just an examination item included in the entire hospital's medical optometry process.
