Evanston Eye Testing
When coming into our Evanston Optical Store, Visual Eyes, for an eye exam you are greeted by our friendly and compassionate staff who will explain that there are several tests as part of your comprehensive eye exam. First Dr. Fernando Mosqueda, or one of our licensed technicians, will ask you about your medical history and any vision problems you may be experiencing. Next, your “visual acuity” (how clearly you can see) is measured, which helps determine your prescription for glasses. Also measured is your eye pressure, for which you my receive drops that enlarge your pupils. After the various tests are performed, Dr. Mosqueda discusses what he found during the exam, answers any questions you have about your eyes, then together you will decide your best plan of treatment, if needed.
Several different tests will be performed during your eye exam at our Evanston optical store, all designed to check your vision and to examine the appearance and function of all parts of your eyes. One such test is an eye muscle test, which examines the muscles that control eye movement, looking for weakness, poor control and even poor coordination. During this vision test, our Evanston eye doctor, Dr. Mosqueda watches your eye movements as you follow a moving object, such as a pen or light, with your eyes. Another vision test is called a refraction assessment, which will determine what specific lens prescription will give you the sharpest and most comfortable vision. With this test light waves are bent as they pass through your cornea and lens, and if they don’t focus perfectly on the back of your eye, also known as your retina, you have “refractive error.” Having refractive error may mean you need some form of vision correction, such as glasses, contact lenses or refractive surgery, to see as clearly as possible.
Your visual field is the total range of what you can see to the sides without moving your eyes. The visual field test determines whether you have difficulty seeing in any areas of your overall field of vision, specifically your peripheral vision. Our Evanston eye doctor will also screen your vision for a color deficiency, especially if you have difficulty distinguishing certain colors like red and green. A slit-lamp examination magnifies and illuminates the front of your eyes with an intense line of light to examine the eyelids, cornea, lashes, iris, lens and fluid chamber which will show any damaged cells. The retinal exam allows Dr. Mosqueda to evaluate the back of your eye and a glaucoma screening is also part of your complete eye exam. You may need more specialized tests, depending on your age, medical history and risk of developing eye disease.
