Your Eye test explained

An eye exam involves a series of tests to evaluate your vision and check for eye disease. Each test during an eye exam evaluates a different aspect of your vision or eye health. 

At Rivoli Vision, every eye examination is tailored to your individual needs, however, a typical visit to our stores would entail:

1. History Taking

As part of the history taking, the optometrist will ask you questions about your reason for visit, family history of medical and eye health conditions including lifestyle diseases like diabetes, hypertension etc., and allergies and any vision problems or symptoms you might be experiencing.

2. Visual Acuity Test

This test measures how clearly you can see. You will be asked to read alphabets or numbers on a screen positioned at a specific distance. The lines of the font type get smaller as you move down the chart. Depending upon the extent of the print you can read, your vision is recorded for each eye separately.

Your near-sighted vision is also tested, using a card with letters similar to the distance eye using a card held at a reading distance.

3. Power of Glasses

If you are already wearing eyeglasses, the power of your eyeglasses will be measured on the Lensmeter, and will then be compared with the power obtained during the current testing.

4. Eye Exam

Following are the aspects of your consultation:


The power of your eyes will be assessed using an auto refraction machine - this is used to see how long or short-sighted you are and helps your optometrist to determine a lens prescription that will give you the sharpest, most comfortable vision. The assessment may also determine that you don't need corrective lenses.

Your optometrist may use a computerized refractor to estimate your prescription for glasses or contact lenses. Or he or she may use a technique called retinoscopy. In this procedure, the optometrist shines a light into your eye and measures the refractive error by evaluating the movement of the light reflected by your retina back through your pupil.

After this procedure, the power of your eyes will be confirmed through a process called subjective refraction where the best spectacle prescription is arrived at based on a series of procedures where you will be asked to compare the clarity of vision with different choices and combinations of lens powers.

If you have eyestrain or visual fatigue, the optometrist will also assess the balance of your eye muscle coordination using few simple tests.


Slit Lamp Examination

In the slit lamp examination, the optometrist will assess the overall eye health including the eye lids, eye lashes, cornea, pupil (black aperture in the center), and will also look for signs of dry eyes, any ocular allergy or infections.


Eye Pressure Testing

If you are above the age of 40, have a family history of Glaucoma, or any medical health conditions that warrant eye pressure assessment, a non-contact tonometry would be performed to evaluate the eye pressure.


Fundus Camera

If you have general health conditions such as Diabetes, Hypertension, etc the optometrist will also evaluate the eye health of the back portion of your eyes using a fundus camera. In such situations, you will be referred for a dilated eye examination to ensure that you do not have any sight threatening complications due to the diseases.
