Quality Eye Exams in Lafayette, IN

When examining your eyes, optometrists use a variety of tests that can help determine your overall health. Diseases, such as, diabetes, hypertension, and autoimmune disorders can be detected through various eye tests during your eye exam. In some cases, optometrists are the first to detect these full-body health problems. 

Types of Vision Tests You May Experience During Your Eye Exam

Below is a list of five common vision tests you may encounter during your eye exam.

  • Retinoscopy: During this test, the lights are dimmed and the optometrist will have you focus on a chart across the room. As you focus on the image, the eye doctor will place a device in front of your eye and shine a light on your eye, while flipping through various lenses. Based on how the light reflects from your eye, the optometrist can determine what kind of prescription you currently have.

    ○ Why: If you already have an eyeglass prescription, but don’t know the exact type when your eye doctor asks, this test can be used to get an approximation of your prescription. 

  • Visual acuity test: Your optometrist uses this test to evaluate your eyesight. Most of us are familiar with this test. One example is the Snellen test. Your eye doctor uses a wall chart to test your distance vision (how well you see at a distance). The chart has several rows of letters that decrease in size as you move down the chart. The optometrist will place you 20ft away from the chart and ask you to read the smallest row of letters you can while covering one eye. This test is done for each eye. Other tests include the Jaeger test and the E chart.

○ Why: The visual acuity test is conducted to detect any vision problems a patient may have or to monitor vision problem already detected during a previous eye exam. 

  • questions to ask your eye doctor in Lafayette INColor vision test: During this test, an optometrist evaluates your color perception. This can help detect color blindness or other diseases that may affect your color perception. This is usually conducted early in the routine eye exam. For this exam, the patient sits at a table, covering one eye, and the optometrist shows him various slides with different patterns of colored dots. The patient then looks for symbols or numbers hidden in the pattern.

○ Why: The color vision test is a part of the routine eye exam. Also, certain job positions where color perception is important may require a color vision screening.

  • Refraction test: An optometrist uses this test to determine the correct lens prescription for you. Using a device called a phoropter, your eye doctor presents you with a series of lens choices to help you determine which one looks clearer. Based on your answers, the doctor is able to fine-tune the lens power to fit your needs.
    ○ Why: Refraction test are important because you want to make sure you are prescribed the correct eyeglass or contact lenses for your needs. This test can also determine the level of astigmatism, farsightedness (hyperopia), nearsightedness (myopia), and presbyopia.
  • Visual field test: This test is used by an optometrist to evaluate your peripheral vision. 
  • Why: The doctor may want to check for blind spots in your vision, which could help detect diseases, such as, glaucoma or even damage to the nerves of the eye caused by stroke or a tumor.

There are other tests that may be conducted during an eye exam, depending on the situation. To find out more about these tests, visit one of our doctors of optometry.

What is 20/20 Vision?

Believe it or not, 20/20 vision is just “normal” vision. If you have 20/20 vision, this means that you can see what people with normal vision can see from 20 ft away. If the number on the right is lower (20/10), then your vision is above normal. If the number is higher (20/60), then your vision is below normal, indicating different levels of vision loss. There are various classifications for visual impairment that optometrists use to evaluate your eyesight.

Tips for Preparing for Your Lafayette, IN Eye Exam:

● Be prepared with any questions you may have for your optometrist. If you have any concerns for the reasons why you are getting an eye exam, be sure to explain them to your doctor. This will also help determine what vision tests (aside from the routine tests) should be conducted during your visit.

● If you wear glasses or contact lenses, bring them with you. You will need to wear them during the exam in order to collect accurate results.

● If you are taking any over-the-counter or prescription medications, let your optometrist know. Certain medications may impact the vision test results.
