Myopia (shortsightedness)

The inability to see distant objects clearly. This condition is very common and affects about 20% of the population. Myopia begins to develop at teenage years and can get worse over time, It tends to stabilize around ages 23-40.

It can be corrected easily with spectacles or contact lenses, providing normal vision. At St George Vision we offer a wide range of trendy and affordable spectacles. If contact lenses are advised St George vision has all the leading brands. The type and brand of contact lenses are prescribed according to your lifestyle best fit and prescription.

Hyperopia (longsightedness)

Hyperopia is the opposite of myopia. Hyperopic people have difficulty seeing near objects. This condition is also corrected with glasses or contact lenses.


Astigmatism is caused by the shape of the front of the eye (cornea) or by irregularities in the lens inside the eye. It affects both myopic and hyperopic people. Astigmatism maybe inherited It is corrected with spectacles or contact lenses.


Presbyopia is a condition that makes vision difficult at near reading distance. It is a normal ageing condition affecting everyone over of 45 years. With age it becomes harder for the lens to change shape to focus on close objects. At St George vision we can prescribe lenses to help you refocus at near objects.

Colour Vision Deficiencies

Colour Vision Deficiencies referred to as colorblindness. A person with color vision defect will confuse some colors (most commonly red and green) and may not see some colors as brightly as someone with normal vision. Colorblindness is inherited and is more common in men.

It is important to test children to determine if they are color deficient so as to make the appropriate career choices. Most people usually compensate for their color deficiency. St George Vision Optometrist will carry several tests to determine if a person is colorblind and what color he or she has a deficiency.


Also known as lazy eye. To see clearly your eyes need to focus on an object and aim accurately at that object. If both eyes are not aimed at the object accurately you may experience double vision. Some people do not develop this ability as children and their eyes tend to turn in or out. Screening children at an early age especially before 5 is recommended for better long term outcome.

At St George Vision our optometrist measures how well your child’s eyes align and how much of a strain it is to keep them aligned. If there is a problem he/she may prescribe glasses or exercises to help.


Cataract is the cloudiness that forms in the lens of our eye. The progression may be slow or in some cases rapid. At St George Vision we assess the lens and see if any cataract is evident. If a cataract is found our St George Vision Optometrist will determine where and how dense it is. This allows us then to advise you if treatment is warranted or just monitoring. In some cases it may take years before surgical intervention is required. Exposure to the UV light and a poor diet increase the chance of developing a cataract. Surgical removal and implementation of a new intraocular lens in most cases is successful. At St George Vision we can refer you to an Ophthalmologist to have your cataracts removed if necessary.


Glaucoma is the disease of the optic nerve with loss of nerve fiber bundles. This may be caused by elevated eye pressure. A comprehensive eye examination at St George Vision we look and detect glaucoma by assessing your optic nerve head, inter ocular pressure and visual field build up of excess fluid in the eye that causes pressure on the optic nerve and eventually destroys the nerve cells that transmit information from the eye to the brain. It may ultimately cause blindness.

It is a dangerous disease as there are no symptoms until permanent damage has occurred. It is referred as the silent disease. Therefore early detection is vital. The test for Glaucoma is simple and painless. If diagnosed it is treated with eye drops that reduce the pressure on the eye, or surgery in severe cases.

The pressure test involves a quick puff of air on the surface of the eye. It may be carried either by a contact or non contact instrument both available at St George Vision. Glaucoma may be caused by injury or is inherited. Common with people over 40 years . A comprehensive eye examination at St George Vision which includes an eye pressure check and a visual field assessment will determine if Glaucoma is present. It is an inherited disease, so regular eye examinations is important to detect the disease early.

Macular Degeneration

Your macula is your area of best vision. With macular degeneration you may see wavy lines while looking at a grid or may have blurry vision in the center of your vision. The early stages maybe asymptomatic. Early detention is vital. Various treatment options are available, but if left too late loss of vision maybe permanent.

Research has shown that a diet rich in Vitamins A,E,Zinc, Magnesium, Selenium, Copper can help slow the progression of the disease. By strengthening the retina.

A comprehensive eye examination at St George Vision will detect signs of macula disease.

Diabetic retinopathy

Diabetes is the leading cause of blindness in the western world. A comprehensive eye examination at St George Vision can detect and monitor Diabetic changes in the eye. These changes can be small or large bleeds, vessel changes and swelling. of the macula. With early detention optimal treatment options are available. The longer the disease has been present the chance of Diabetic retinopathy is present. There at St George Vision we recommend all diabetic should be screened routinely for diabetic retinopathy. Our Fundus Retinal Camera we take and keep images of your retina which allows us to compare the photos over time and monitor any changes.

Floaters and Flashes

Floaters occur in the vitreous, which is a jelly like substance attached to the retina. They are deposits of natural material. Floaters tend to increase in number as we age but can be present at any age. They may appear as a spot, thread, small insect or cobweb. If you see floaters it is important to see an optometrist. At St George Vision our optometrists can assess the floater to rule out retinal detachment which requires emergency treatment.

If you see a flash in one eye that looks like a lightning bolt or a light bulb flickering on and off, please see an optometrist or an ophthalmologist urgently as this may be a retinal detachment.

Dry eye

Dry eye is a very common condition. It usually affects more women than men. The symptoms include a gritty, burning sensation, watering and blurred vision. The optometrists at St George Vision can determine of dry eye is present and in many cases the cause.

Dry eye can be due to insufficient tear production or an unstable lipid layer which protects the eye from drying out. Dry eye does not mean no tears, in many cases it means the tears are not working effectively. Contact your St George Vision optometrists to discuss your concerns and treatment options available.
