Visual acuity

This is the first comprehensive eye test. It is the regular eye test procedure where you are shown a chart and you read it out from 20 feet away.

To check your near vision, a small acuity chart is shown at a handheld distance. By this test, you can generally know if you have myopia, hyperopia or presbyopia.

Colour Blindness

People having colour blindness perceive some colours differently. Extreme cases of colour blindness have difficulty in differentiating between red and green, which are the most important traffic lights. These people are not allowed to drive. Mild cases of colour blindness often go unnoticed until you take a test yourself. In the colour blindness test, you are shown few colourful charts with numbers or patterns in them.

Eye Alignment

Checking eye alignment is important. It helps you in knowing if both your eyes are functioning properly. Usually, you view things from the perspective of your dominant eye. If there is a problem with your non-dominant eye, you won’t find it sooner. Also, there are issues like strabismus or squinting which distorts your vision. This test helps in finding out that.

Usually, this is done through a cover test, where you cover one eye and check the acuity of your eyes.

Eye Movements

This test, known as the ocular motility test, finds out how fast your eyes respond to moving objects. Your eye movements are important if you are related to sports, military or any profession where your reaction speed is important.

Depth perception

This test is called stereopsis. You are given 3D glasses and some test patterns to recognise. It will help in determining your perception of depth and the normal 3-dimensional nature of objects.

Retinoscopy

This test is used to determine which lens power will give you accurate vision. This test gives an accurate eye prescription.

Refraction

This test is done using a phoropter and it helps in accurately determining what type of vision defect you have, whether it is myopia, hyperopia, presbyopia or astigmatism.

Aberration

This test is normally done for children or patients who cannot respond to visual acuity test. This also helps in determining the type of vision defect.

Eye condition

To check on the health conditions of your eyes, the opticians take a slit lamp test on your eyes. With this, the doctors closely examine the structure of your eyes using a slit lamp or a binocular microscope. It helps in determining diseases like cataracts, conjunctivitis, macular degeneration, corneal ulcers etc.

Glaucoma

Diseases like glaucoma are incurable. Diagnosing them at earlier stage help in curbing the extent of the disease a lot. You can save your eyesight wear your favourite clear frame glasses and show off your style.

Pupil Dilation

Your pupils are dilated with a dilation solution to take a closer look inside your eyes. This is done to check for eye health and conditions.
