We help your whole family to see better with our holistic approach to vision.

Regular eye tests are vital for early diagnosis as many eye conditions may be symptom-free for some time.

MYOPIA (SHORT SIGHTEDNESS)
The eyeball is either too long or the cornea and crystalline lens power are too strong, causing light rays to focus in front of the retina. This can be corrected with concave, diverging or minus (-) lenses.

HYPEROPIA (LONG-SIGHTEDNESS)
The eyeball is too short or the cornea and crystalline lens power is too weak, causing light rays to focus beyond the retina. This can be corrected with convex, converging or plus (+) lenses.

ASTIGMATISM
Astigmatism occurs when the front of the eye, the cornea, has an uneven curvature. Instead of being spherical, it is egg-shaped. When light hits an irregularly curved cornea, it is not focused correctly onto the retina which results in blurred vision. This can be corrected with a lens that allows light to correctly focus on the retina.

PRESBYOPIA (AGE RELATED READING DIFFICULTY)
This is when the crystalline lens of the eye becomes stiffer and loses its ability to focus on close objects. This condition usually becomes noticeable in the early to mid 40s and is a normal part of ageing. Presbyopia can be corrected with reading glasses, bifocals or progressive lenses.

COMPUTER VISION SYNDROME
When using computers your eyes must focus and refocus constantly. Your eye muscles need to make very precise movements to allow you to work smoothly. Your eyes look up, down and sideways from the screen to other objects and need to refocus to see your keyboard or other objects. This requires a great deal of effort from your eye muscles.

If you have an existing eyesight problem, working on a computer for a prolonged period of time can exacerbate it. So, it’s important to wear glasses if you have them. If you need glasses but don’t have them, or if you wear the wrong prescription for computer use, you might find you could be working much better after a proper assessment.

The most common symptoms of Computer Vision Syndrome or digital eyestrain are:

  • Eyestrain
  • Headaches
  • Blurry eyesight
  • Dry eyes
  • Neck and shoulder ache

SPOTS OR FLOATERS
These are small particles in the ‘jelly’ or liquid part of the eye (known as the vitreous) that become noticeable when they move in your line of sight. They are more noticeable when you are looking at a bright or plain background, which is why people notice them more when looking at a blank surface or at the sky.

Spots are often triggered by tiny specks of protein or other matter that come to be entrapped when your eyes developed before birth. They can also emerge as the vitreous fluid fades caused by aging. Specific eye diseases or injuries can bring about the emergence of spots.

PTERYGIUM
Pterygium is an excessive growth of tissue that forms on the white part of the eye. It can be found on both eyes, usually on the part closest to the nose. Pterygium isn’t dangerous but should be checked to ensure it isn’t something more concerning.

It is not known the exact cause of pterygium, one reason is that excessive exposure to ultraviolet light can lead to the growths. This happens more often in people who spend a lot of time outside in sunny or windy conditions. If your eyes are subjected to specific factors (pollen, sand, smoke, wind) constantly you have a greater risk of developing this condition.

CATARACTS
A cataract is a clouding of the lens in the eye. It usually occurs as people age. A cataract is not harmful, and treatment may not be needed in the early stages, but as the cataract progresses it may affect vision. If this happens we would refer you to an eye specialist who can treat the cataract surgically.

MACULAR DEGENERATION
Age-related macular degeneration (AMD) is a common condition that affects many people, usually over the age of 65.

This condition affects the macula area, a small part of the retina at the back of the eye. Damage to these cells causes distortion of central vision and in some cases can cause a painless loss of central vision.

There are two main types of AMD: “dry” and “wet”.

Dry AMD is the more common type. It develops very slowly and causes a gradual change in central vision. In more severe cases, dry AMD causes a blank patch in the centre of your vision in both eyes. It doesn’t affect the peripheral vision and it does not lead to complete blindness.

Wet AMD develops more rapidly, so it impacts central vision in a shorter time. Neither type of AMD will cause the loss of peripheral vision and blindness.

GLAUCOMA
Glaucoma describes a number of conditions that damage the optic nerve and affect vision. It is typically seen in people over the age of 45 and occurs when the fluid in the eye builds up and adds increased pressure on the optic nerve. It can also occur because of a weakness of the optic nerve due to a poor blood supply, or because of some other type of weakness of the nerve.

The condition can present in two ways.

  1. In the acute form (which is rare), it shows up as a painful, red eye with reduced vision.
  2. In the more common, chronic from, a patient may not be aware that they have the condition. It may only be detected during a routine eye examination.

The chronic form of glaucoma usually progresses slowly causing irreversible damage to the visual field. However, if detected early, it may be treatable. Once the pressure that is causing the problem is controlled, further damage to the eye and visual field is usually prevented
