How to take an eye test?

Eye exams are crucial for the health of eyes

Eyes are the windows of human’s hearts. It’s very important to have eye exams every year or six months, because many eye problems such as cataracts, retinal problems and glaucoma offer no telltale symptoms.

Routine eye exams mainly contain several steps. The first step of an eye exam is a measure of visual acuity. Eye doctors usually use a specially designed pocket eye exam card holding at about 14 inches before patient, or a standard eye exam wall chart with a distance of 20 feet. Each eye is tested independently while the other one is covered, to confirm the smallest characters patients can read. The letters at the last column of the eye exam card provide the patient’s acuity compared with normal subjects. For example 20/200 means the patient can see at 20feet when a normal one can see at 200 feet, what indicates that the patient’s vision is very lousy. The patient can also wear his glasses to finish the same eye exams, the result are called “best corrected vision”. The second step of an eye exam is pinhole testing to determine if the eye problem is a result of refractive error. Then the observation of external structures and testing extra-ocular movements are carried out for eye exams. After that, eye doctors will use the ophthalmoscope to do closer eye exam of the outer structures of the eye and view the retina and associated structures. If needed, the eye doctor will also measure the fluid pressure in the patient’s eyes. High pressure may be a symptom of glaucoma.

Besides routine eye exams, you may also visit your eye doctor for the information of eye fashion trends or choosing eyeglasses.
