Eyes reflect the language of our minds. The eyes are sensory organs that enable us to view and perceive the world around us. They allow us to collect visual information and convert it into electrical signals that the brain can interpret. The process of visual perception helps us navigate our environment, recognize objects, and interact with others. Eyes are important for non-verbal communication and conveying emotions and can provide important information about a person’s overall health and well-being. Altogether, the role of our eyes is essential to our daily lives and plays a significant role in our physical and emotional experiences.

The section will discuss different types of tests, which are usually part of a routine eye exam. The vision screening tests evaluate a different aspect of your vision and eye health. 

Most Important Eye Examination Tests 

Visual Field Test

The eye test helps you determine your field of vision for the area right in front of you or what you can see without moving your eyes. The eye checks your peripheral vision. As there are a few different types of visual field tests, the most common procedure among them comes with a device called an auto perimeter. The test provider operates a computer program that flashes small lights when you are looking into the bowl-shaped auto perimeter. You only need to press a button when you see the lights. 

Visual Refraction Eye Test

Refraction refers to the way light waves meander as they pass through the cornea and lens. The visual refraction assessment helps your ophthalmologist determine whether you need vision correction and the corrective lens prescription, which will offer you clearer vision. Your vision test provider might use a device named a phoropter to examine your refractive error. Eye health professionals perform the test in a dark room to help you better your view through the phoropter lenses. When you repeat these steps several times, it will help your test provider find the right glasses or lenses that can give you the best possible vision. 

Glaucoma Test 

The test assesses the pressure inside your eye, which is known as intraocular pressure. The pressure helps your eye doctor detect whether you have glaucoma. The disease causes pressure inside your eyes and can result in blindness. If caught early, your doctor can treat the disease. One of the most common tests to measure eye pressure is non-contact tonometry. The device called a tonometer injects an air puff into your eyes to test the pressure. Another common Glaucoma test is called pachymetry, which assesses the thickness of your cornea, which reflects your intraocular pressure measurement. 

Slit-lamp Test

A slit-lamp is a microscope where your doctor uses intense light to enhance your eyesight, so your doctor can check the cornea, lens, iris, and anterior chamber. While testing your cornea, your provider might apply eye drops in your eyes containing fluorescein dye. The orange dye makes the process easier for your eye doctor to look for small cuts, scrapes, tears, foreign objects, or infections on your cornea. When you blink, your natural tears clean the dye away.

Visual Acuity Test/Vision Screening Test

Specsavers eye test is an eye chart test that you might be familiar with. The doctor will make you sit 20 feet away from the chart and ask you to identify a series of letters printed on a chart. The official name for the chart is Snellen Eye Chart. The letters become smaller as you move down the chart. The patients need to cover one eye and read the chart aloud, and vice versa. 

Retinoscopy

In retinoscopy, you have to stare at a large target through a machine called a phoropter. During the process, your eye test provider shines light in your eyes and flips the light through a series of lenses. The test lets you know whether you need eyeglasses or contact lenses. 

Color Blind Test

The test examines color blindness by assessing your ability to identify different colours. The test provider might ask you to detect a number or a letter formed with multicolored circles. 

Fundoscopy 

In this test, your doctor puts special eye drops in your eyes to dilate them. You need to wait for 15-20 minutes for the solutions to effect. You might notice that the light deems brighter during the test. The doctor looks at your optic nerves, cornea, and retina through this test. 

Corneal Topography 

While you are staring at an object, your doctor takes thousands of images of your eyes to assess your corneal shape. The vision screening test can help them see whether you have astigmatism. The medical process helps your doctor create contact lenses that fit your eye and help them prepare for surgeries. 

To Conclude,
