Aier Eye Hospital Affiliated to Wuhan University

Optometry and glasses

Why are there so many inspection items?

It took several hours

A friend came to the Aier Eye Hospital Affiliated to Wuhan University (Aier Eye Hospital Group Hubei Headquarters) to get glasses a few days ago and made such a complaint.

In the eyes of most people, fitting glasses is a simple matter. They just need to test their vision and astigmatism, try lenses of various degrees until they can see clearly, and then pick a pair of beautiful frames. Then they can sit back and wait for their glasses. However, fitting glasses at the Aier Eye Hospital Affiliated to Wuhan University (Aier Eye Hospital Group Hubei General Hospital) is not so "quick". Is it intentional to delay the patients' time or is there another mystery? Come and have a look.

01. Optometry should be "complex"

In the minds of many people, optometry and glasses fitting are very simple, but in the eyes of optometrists and optometrists, optometry is a very "complicated" matter. Measuring vision and trying on lenses of various degrees alone is not enough to obtain reliable optometry data. The fitted glasses may not be comfortable to wear, causing dizziness, eye swelling and other problems, and may also accelerate the progression of myopia. At the same time, decreased vision does not necessarily mean myopia. Simplifying optometry may lead to some eye diseases being ignored, bringing additional risks to eye health.

02. What are the examinations included in “complex” optometry?

It is recommended to choose a professional optometry institution for optometry. In addition to checking vision, medical optometry also requires the following examinations:

Optometry: including computer optometry, retinoscopy, subjective optometry, etc., to understand the type and degree of myopia;

Axis and corneal curvature: The occurrence of myopia is related to the changes in the axial length and corneal curvature. This can help us understand the progression of myopia and provide a basis for myopia correction plans.

Binocular vision function test: The two eyes do not work independently, but "work together" to understand their ability and status of working together.

03. Slit lamp, intraocular pressure and fundus examination

For those whose vision correction is not ideal during the optometry examination, after excluding the problem of refractive error, they need to go to the ophthalmology clinic for basic eye examination to rule out other eye diseases...

Zhou Chao, a member of the Medical Technician Branch of the Chinese Medical Association, a national first-level (senior) optometrist, and director of the Optometry Center of the Aier Eye Hospital affiliated to Wuhan University, explained: Optometrists and optometrists will also arrange other examinations based on individual circumstances, and then combine the individual's eye use scenarios and needs to give appropriate eye examination prescriptions.
