What is Eye Testing?

An eye test involves a series of tests to evaluate your vision and check for eye diseases. Your eye doctor may use a variety of instruments, shine bright lights directly at your eyes, and request that you look through an array of lenses. Each test during an eye exam evaluates a different aspect of your vision or eye health.

When To Go For An Eye Exam?

When it comes to scheduling preventive health appointments, eye exams are often overlooked. Seeing a licensed optometrist or ophthalmologist for comprehensive exams is important for everyone’s overall health. 


Enhancing your eyesight is important because millions of people over age 12 need vision correction but it’s just one of the reasons to get your eyes examined. Regular eye exams are an important part of finding eye diseases early and preserving your vision. You should have an eye exam, if any of the following conditions follows you.


  • Red, dry, or itchy eyes. 
  • Spots, flashes of light or floaters in the eyes.
  • Diabetes or another health condition that affects your eyes.
  • Family history of conditions like diabetes or glaucoma.
  • Can’t remember when you last had an eye exam. If it’s been longer than a year, you’re overdue.
  • Difficulty driving at night and seeing street signs in the dark.
  • Experiencing eye strain, headaches and/or blurred vision after spending an extended amount of time in front of a computer screen. 
  • Getting motion sick, dizzy, or having trouble following a moving target. 
  • Holding books or the newspaper away from your face and, or closing one eye to read them clearly. 
  • Noticing any changes in your vision, especially after an incident of head trauma.

Common Eye Tests

There are different types of eye tests depending on the eye conditions and problems the concerned person is facing. These could be-

1. Visual Acuity Test

You will read letters from a board placed at a particular distance from you using both the eyes one by one. Your ophthalmologist utilizes your feedback to decide how each eye’s vision level balances to standard 20/20 vision.

2. Retinoscopy

A machine called a “phoropter” is used by your ophthalmologist to conduct a retinoscopy. Probably the thick machine you must have imagined sitting in front of while your ophthalmologist examines your eyes, with many dials and keys on it. A retinoscopy allows the ophthalmologist to estimate your optimal lens prescription. As you gaze through the phoropter, the eye doctor flips different lenses in front of your eyes. You focus on a prominent object in front of you. The optometrist shines a light into your eyes and watches how the light affects your eyes with different lenses.

3. Refraction Test

Along with a retinoscopy, a refraction test determines your eyeglass prescription. You also gaze into the phoropter and look at the eye chart on the opposite wall during this vision test.

Throughout the test you see a series of lens pairs. The optometrist repeatedly asks you which of two lens options lets you see more clearly. Based on your answers, the optometrist determines whether your eyes are nearsighted, farsighted, or affected by astigmatism. This test may also show that you don’t need prescription vision correction.

4. Keratometry Test

This test measures the shape and curve of the outside of the eye, known as the cornea. The cornea’s shape affects how your light perceives and reflects light. Some people have corneas with steep or elongated curves, which results in a condition known as astigmatism. Optometrists use keratometry tests to detect astigmatism.

During a keratometry test, you gaze into a special machine. Your eye doctor adjusts the machine so it aligns with your eye. Then the optometrist reads the machine’s measurements, which indicate your cornea’s shape.

5. Peripheral Visual Field Test

While people tend to focus on whatever our eyes look directly at, we can also see objects on the sides of our field of vision. This viewing area is known as our peripheral vision. Visual field tests evaluate our peripheral vision.

Several types of peripheral visual field tests exist. They include the following:

  • Automated perimeter: You look into a special machine and focus on a spot in the center. You press a button any time you see a light flash in your peripheral vision.
  • Tangent screen exam: You focus on a target at the center of a screen. Your eye doctor moves objects in and out of your peripheral vision, and you indicate when you can first see them and when they vanish from your field of view.
  • Confrontation visual field exam: Your eye doctor sits opposite of you and moves his or her hand into and out of your peripheral vision. You say when you see the hand and how many fingers your optometrist is holding up.

Each test allows an optometrist to identify gaps in your peripheral vision and determine the size of your visual field

6. Intraocular Pressure Measurement

An intraocular pressure test examines the pressure created by the fluid in your eyes. An abnormal level of eye pressure can be a warning sign of glaucoma.

The machine that tests for glaucoma sends a quick puff of air at your open eye. The puff of air briefly surprises you, so your eye reacts by closing. The machine then measures your eye pressure based on your reaction and your eye’s resistance to the pressure from the air puff.
Your ophthalmologist may perform a manual intraocular pressure measurement as well to get a more precise reading. This test uses special instruments that gently touch your eye to measure the internal pressure. Before the test, the ophthalmologist  will apply anesthetic eye drops to ensure you don’t feel the instruments during the test.

These descriptions of common eye tests should make it clear that eye exams are simple and painless. Make regular visits to a local eye doctor so your eyes can receive these important tests. If your optometrist performs additional tests at your appointment, ask him or her to explain them.

Importance Of Eye Test

Preventing damage and sight loss is one of the gifts to yourself. More than 50 percent of sight loss is preventable, so getting your eyes tested can help prevent, or limit, the damage caused by certain eye conditions.


Regular eye examinations are essential because:

  • Having your vision corrected can enhance the standard of day-to-day life.
  • They will help spot certain eye conditions such as cataracts, glaucoma and age-related macular degeneration, which could lead to sight loss.

An ophthalmologist  may also be able to detect the symptoms of some bigger health conditions with symptoms that affect the eyes, such as diabetes and high blood pressure.Eye examinations for children are vital to make sure that any visual difficulties such as squint, lazy eye or short-sightedness are detected and treated early.

An eye test is performed to check various ailments of the eyes. An ophthalmologist will try to understand if you have any eye conditions or if your sight is weak. Your eye doctor will take several tests with various instruments, bright lights, and will try different lenses to effectively solve the problem.

It is recommended to not wear any eye makeup on the day of your eye examination. As the doctor may need to use eye drops for some tests. And if you are wearing any makeup, keep it minimal. 

Some diseases cause serious eye ailments. So, an eye ailment can tell if you are developing related diseases. For example, diabetic retinopathy, a condition developed in diabetics. Other health problems detected during eye tests could be high blood pressure, high cholesterol, and rheumatoid arthritis. 

You can improve your eyesight by maintaining a healthy lifestyle. Eat vitamin rich foods like green vegetables, carrots, and fruits with healthy nutrients. You should always exercise at least thrice in a week. 

You should do an annual eye checkup, even if you feel nothing wrong with your eyes. Because certain ailments develop very slowly but are hard to recover from. If you have a family history of eye ailments, then talk to your eye doctor.

No. There is no proof that contact lenses harm your eyes. However, one should remember to be careful with them. If you wear contact lenses remember to wash your hands before touching them, and keep them at a safe place. You should always check the expiry date of contact lenses.

You are advised to get the child’s eye tested before he/she enters school. If you notice any problem like, baby rubbing the eyes or complaining of headache, then you should consult an paediatric ophthalmologist as soon as possible.
