You can see well from near and far, you don’t have any headache, your eyes don’t feel dry, so what’s the point? Do you really need to get your eyes examined by an optometrist?
The answer is very simple: optometrists recommend taking an eye exam every 2 years for adults, even if you do not have a particular problem. Just like when you go to the dentist without having a specific problem with your teeth, your eyes may suffer from certain eye diseases even if you do not feel the repercussions for now. The dentist allows you to maintain good oral hygiene while the optometrist takes care of the health of your eyes. Thus, with the help of sophisticated instruments and thorough examinations, the optometrist will be able to detect the warning signs of a possible illness to be able to inform you quickly. The purpose of an eye exam is not only to evaluate your vision, but also and above all to make sure that you do not suffer from an eye disease.
During an eye exam, which can last from 30 to 45 minutes, you will pass several tests allowing your optometrist to measure your visual acuity, determine your prescription and check the health of your eyes.
Here are some of the tests performed and the instruments used:
• Ocular tonometer: The ocular tonometer measures intraocular pressure (IOP). This instrument is primarily used to detect the presence of glaucoma, an eye disease that can cause blindness if left untreated. Optometric assistants may use some type of tonometer to perform this test before you meet the optometrist. Sometimes the optometrist checks pressure from your eyes with another type of tonometer.
• Snellen Eye Chart: This chart is probably the best-known component of an eye exam. It is usually projected onto a screen placed on a wall of the examination room at a distance. There are several lines of random letters and decreasing size. This tool allows the optometrist to measure your visual acuity (the clarity of your vision). For example, if you can distinguish small characters from a good distance, he will be able to verify if you have good visual acuity.
• Visiometer: A visiometer is this tool in looks like large glasses and that will help the optometrist determine your prescription. This tool can also measure refractive errors (myopia, hyperopia or astigmatism). While you pass this test, you will have to look through several lenses and indicate the clearest image according to different options. The optometrist will ask you several times to choose between two lenses to find the power that will improve your vision by following different steps to ensure the accuracy of the results.
