Contact Lenses

Contact lenses are listed by the Health Science Authority of Singapore as medical Devices. It is therefore only available on prescription by Optometrist and Medical practitioners. Every contact lens importer , must apply for a license to bring in contact lenses into the country. This ensures that contact lenses imported are of high quality and comply with safety standards. There Are Two Components To Purchasing Contact Lenses. The Contact Lens And The Professional Service. The Purchase To ensure you continue wearing your contact lenses safely, both these components must go hand in hand. It is very important to safeguard yourselves from fake branded contact lenses by buying from reputable contact lens practices. I say this because we have had an occasion where fake lenses were identified and confiscated by authorities here in Singapore.

Preparing for your eye exam

Your Optometrist will ask several questions regarding your health and that of your family.

Binocular Vision Assessment

Binocular vision is normal when both eyes are able to fuse images of the same object together without much effort when looking at both distance and near. When we switch from viewing a distant object to reading text on a page, our eyes converge in order to avoid double vision. When looking up, down, right or left at a distant object, both our eyes should move in the same direction to keep the images fused. They are four muscles in each eye that controls the eyes movement. These muscles are controlled by nerves. If a problem occurs in any of the nerves and/or any of the muscles it innovates, double vision may occur in some or all positions of gaze.


The Topograph is today an indispensable tool in any Hi Tech Eye Clinic, dealing with state-of-the-art customized contact lens design. It provides useful data of the shape and form of the corneal surface, including the presence of optical distortions.


The term refraction means to bend light. Your optometrist will use several methods to bend or change the direction of light coming from a distant object, to focus accurately on the retina by introducing different lenses before your eyes. When this is achieved, vision will be clearest. This results in the prescription for your spectacles or contact lenses. Refraction can only be accurate if the letter chart is at least 6 meters or 20 feet away from the patient. Any shorter, and the accuracy drops. To save space, most practitioners will use a mirror to double the distance.

Diabetic Screening

What is Diabetic Retinopathy? Diabetic retinopathy is the leading cause of blindness in the world. If you are suffering from diabetes, it is important that your blood sugar level is controlled. You should also have a dilated eye exam by an ophthalmologist at least once a year.
