Eye and Vision Exams at our Epic Vision Eye Centers
Eye exams are important for maintaining and improving sight, and clinics like Epic Vision Eye Centers recommend having them annually. What many don't realize, however, is that there are different types of exams that can be obtained. Below is some information about the major varieties and what they are meant to accomplish.
Comprehensive Eye Exams
For most people, these are the gold standard for eye examinations. They combine acuity testing with checks for a variety of eye diseases. Visual acuity testing determines the prescription strength for glasses or contacts, and is done before the rest of the exam. In most cases, you will look at an eye chart, but there's more to acuity testing than that. Tests for peripheral vision, reading-distance vision, and more may be included.
The rest of a comprehensive eye exam involves dilating your eyes, or more specifically, your pupils. A drop or two of medicine is placed in each eye to make this happen, and the effect lasts for several hours. Once the pupils dilate, the doctor can look through them to see your retinas and other eye structures. This lets him or her spot any disease processes that are going on.
After this part of the examination, various other tests may be done. One such test is for glaucoma and involves using a machine to blow puffs of air at your eyeball. This helps detect the amount of pressure within it. High pressure in the eye is a hallmark sign of this eye disease.
Diabetic Eye Exams
These exams are done in much the same way as comprehensive eye exams, but special attention is paid to detecting diseases that are strongly associated with diabetes. Such diseases include all forms of diabetic retinopathy as well as glaucoma and cataracts. While glaucoma and cataracts aren't specifically diabetic problems, diabetics have an increased risk of getting them.
Children's Vision Screenings
Vision screenings are not eye exams. Instead, they're quick tests of visual acuity. Typically, they take just a few minutes to perform and may be as simple as having the subject read off of an eye chart.
The purpose of a vision screening isn't to diagnose disease, but to find kids who may be having trouble seeing. Those who fail the screening are then recommended to go to an eye doctor for a proper exam. These screenings are typically sponsored by schools or local eye clinics, and their speed allows the operators to screen an entire school's student body in just a few days.
Notably, passing a vision screening doesn't necessarily mean that your child doesn't need eye treatment. Instead, they are good at catching the worst cases. While that's better than nothing, it's still a good idea to take your child to an optometrist for an annual exam regardless of screening results.
Visual Acuity Testing
At some eye clinics, people can get a quick exam that only provides enough information for a prescription for eyeglasses or contacts. Such clinics are focused on selling glasses, not providing care for total eye health. While we do not recommend this sort of exam, we acknowledge that it can be useful for someone who has broken his or her glasses and needs a new pair cheaply and quickly. We suggest that a full exam be obtained once the immediate crisis has passed.
