A comprehensive eye exam includes a number of tests and procedures to examine and evaluate the health of your eyes and the quality of your vision. These tests range from simple ones, like having you read an eye chart, to complex tests, such as using a high-powered lens to examine the health of the tissues inside of your eyes. Eye care is just like whole body care, having regular, annual vision screening and eye exam procedures are important to keeping your eyes healthy.
Going to a comprehensive vision screening never seems like a big deal until it’s time for the dreaded eye puff test. While this eye exam test is uncomfortable and startling, it is necessary to check the eyes’ intraocular pressure, or IOP—the pressure within the eye. This eye test releases a small amount of air directly into the eye then bounces the air back into the tonometer and reads the IOP. Measuring the IOP is the best way to check for glaucoma and other diseases, making sure the pressure isn’t too high which can damage the nerve fibers behind the eye. Experiencing high pressure in the eye can lead to vision loss and because there are little to no symptoms of high pressure, it is imperative to have regular eye exam tests to check the IOP.
Undergoing a noninvasive, tiny puff of air is comparatively easier to other tonometry tests, which include eye-numbing drops then a probe that pushes the cornea down to test the eyes’ pressure. So at your next vision screening you can sit down at the eye puff machine knowing that it’s not so bad!
