At all of our stores eye examination is conducted by a professional Optometrist. The Optometrist ensures that each and every patient is provided with the best comprehensive eye examination and thereafter with the proper treatment of any vision related problems by the use of glasses, contact lenses, low vision aids or vision therapy.

The best way to ensure good vision is through regular, comprehensive eye examinations. In addition to ensuring proper eyesight, regular exams allow the early detection and treatment of diseases.

The general eye examination has five basic steps:

-         Case History

-         Visual Acuity

-         Slit Lamp Examination

-         Auto Refractometry/ Retinoscopy

-         Subjective Refraction

Additional procedures such as Keratometry, Tonometry, Binocular vision assessment, Colour vision assesment may be required for various patients o a case to case basis.



Here in the patient will need to supply information about their visual and general health history, medications, signs and symptoms of vision problems and other background information.

 These are divided into 3 categories:

Ocular: The physical condition of your eye, including past injuries, infections, surgeries, changes in vision correction, previous eye examination etc.

General: Lifestyle of the patient, including the past and current condition of your health, what medications you have taken, plus cigarette smoking etc. Also the general reading habits of the patient, visual needs for playing sports, driving, computer use etc.

Family: Family members with health issues such as high blood pressure, diabetes, thyroid dysfunction, coronary artery disease etc.. Also history of family members having any sort of refractive error.


Visual acuity is a measure of the spatial resolution of the visual processing system. VA is tested by requiring the person whose vision is being tested to identify so-called letters on a viewing screen.

The test is used to determine the vision of the patient without the use of any sort of correction.

This test determines how well your eye can recognize and differentiate images, letters and symbols. It is measured for distance and near vision with standardized eye charts, at standardized testing distances, under specific lighting.

Normal visual acuity is commonly referred to as 6/6 vision. A human eye with nominal performance is able to separate contours that are approximately 1.75 mm apart at a distance of 6 metres.


The Slit Lamp Biomicroscope is an instrument which is used for evaluation of the external parts of each eye and the surrounding associated tissues and fissures. The Optometrist examines the eyelids, eyelashes, conjunctiva, iris, cornea, crystalline lens and the anterior chamber. The binocular slit-lamp examination provides a stereoscopic magnified view of the eye structures in detail, enabling anatomical diagnoses to be made for a variety of eye conditions.


Refraction is a process your eye care professional uses to measure your refractive error, or vision problem. During a comprehensive eye examination, your Optometrist uses refraction to determine how much power is needed to bring your eyes to normal, perfectly focused vision. Your doctor will decide if glasses, contact lenses or laser vision correction will yield you the most clear eyesight. Refraction consists of two parts, objective and subjective.

An objective refraction is a refraction obtained without receiving any feedback from the patient. An objective refraction is obtained by using different instruments. Your doctor will use a retinoscope or auto-refractor to measure your refraction without asking for subjective responses from you.

Retinoscopy: One of the most common instruments used for objective refraction is the retinoscope. Using a retinoscope, your doctor will project a streak of light into your pupil. A series of lenses are flashed in front of your eye. By looking through the retinoscope, your optometrist can study the light reflex of the pupil. Based on the movement and orientation of this retinal reflection, the refractive state of your eye is measured.

Auto-refraction: Another instrument used for objective refraction is an auto-refractor. An auto-refractor is a computerized instrument that shines light into your eye. The light travels through the front part of your eye to the back part of your eye, then back again. The information bounces back to the instrument, giving an objective measurement of your refractive error.

Retinoscopy performed by an experienced optometrist has been found to provide a more accurate estimation of refractive error than autorefraction.




A subjective refraction requires responses from the patient. The optometrist will use a trail frame to measure your subjective refractive error to determine your eyeglass prescription. Typically, you will be asked to wear a trail frame and look at an eye chart. Your optometrist will change lenses and other settings while asking you for feedback on which settings give you the best vision.

This eye test determines your final spectacle or contact lens prescription.

Sometimes the optometrist prefers to obtain a cycloplegic refraction, especially when trying to obtain an accurate refraction in young children who may skew refraction measurements by adjusting their eyes. Cycloplegic eye drops are applied to the eye to temporarily paralyze the ciliary muscle of the eye and may cause blurriness of near vision for a short period of time.


Additional testing may be needed based on the results of the previous tests to confirm or rule out possible problems, to clarify uncertain findings, or to provide a more in-depth assessment.

Some tests such as Keratometry and Tonometry may be required for certain patients.

At the completion of the examination, your optometrist will assess and evaluate the results of the testing to determine a diagnosis and develop a treatment plan. He or she will discuss with you the nature of any visual or eye health problems found and explain available treatment options.
