A basic overview of the eye check-up process is as follows:
All eye checkups begin with an overall general examination with the torch. All examinations are done in dim light conditions.

Retinoscopy
It is done to estimate your spectacle prescription objectively.

Auto refractors OR Aberrometers
Our optometrists use an auto refractor or an aberrometer to automatically determine your prescription. For automatic prescription as in case of both device usage, a chin rests stabilizes your head and you are asked to look at a pinpoint of light or other image.
An auto refractor evaluates the way an image is focused on your retina, where vision processing takes place, while an aberrometer uses advanced wave front technology to detect even obscure vision errors based on the way light travels through your eye. Aberrometers are used for custom or wave front LASIK vision correction procedures.


Refraction
This is a test normally used by our optometrist to determine the exact prescription. During refraction, she/he places an instrument called phoropter in front of your eyes and shows a series of lens choices to determine which of the two lenses makes you see clearly. After which, the lens that gives you a clearer view is prescribed.

Cover Test
Cover test is the simplest and most commonly used procedure to check the coordinate use of both your eyes. During a cover test, the optometrist asks you to focus on an object at a distance target to begin with followed by a near target. The Optometrist then covers each of your eyes alternately while you stare at the target.

Slit-Lamp Examination
The slit-lamp also called as bio microscope is an instrument that our optometrist uses to examine the health of your eyes. By use of this instrument, the optometrist sees a magnified look of the structure of your eye and can thoroughly investigate the signs of an infection or a disease.
During this examination, the optometrist requests you to place your chin on the chinrest and then will shine the light of the lamp at your eye and will carefully examine the structure and each part of eye inside. A whole range of diseases and infections can be detected with slit- lamp examinations.
The above mentioned are some of the mandatory tests performed during comprehensive eye examinations. However contact-lens examinations and laser surgery work-ups require more specialized and additional tests. Regardless of the type of test performed, it is important that you follow directions closely and ensure accurate results through thorough examination of your eyes.

Please explain the difference between a vision screening and complete eye exam.
Vision screenings are general eye tests wherein a patient is made to read a chart at a certain calculated distance. Only Visual acuity is tested during the screening. Any defective vision detected is then referred for comprehensive checkup.
A comprehensive eye examination can be performed only by an institutionally trained optometrist and it includes careful examination of all aspects of vision. Depending on the results, the optometrist will recommend a treatment plan as per the individual needs that include spectacles or contact lenses, eye exercises or surgery for muscle problems, and medical treatments.
