Eye Defects

The best way to protect your vision is through good general health. A balanced diet includes all the essential nutrients needed by your eyes for each visual mechanism. Examination by a specialist is critical to identify eye problems. Safety and correction of vision defects is also important.

Below are some of the common eye defects. If you are concerned see an optometrist today.

COMMON EYE DEFECTS

PRESBYOPIA

Presbyopia is a condition associated with the natural ageing of the lens within the eye. The ability to focus on close objects diminishes; this usually affects people in their mid forties. It is not a disease and can easily be corrected with prescription lenses.

SPOTS, FLOATERS & FLASHES

Spots, floaters and flashes can all be part of the natural changes in the eye. They can affect anyone at any age. These shadows and "light shows" are seen in our line of sight. If a sudden increase in spots, floaters or flashes occurs, then we suggest seeing an optometrist as medical attention may be required.

ASTIGMATISM

Astigmatism is a common visual defect and is found in most people. It is caused by an irregular shaped cornea which blurs and distorts your eyesight. Special prescription lenses or contact lenses are used to correct astigmatism. We recommend regular eye checks to monitor the condition.

COLOUR BLINDNESS

Colour blindness is a vision defect where colours appear different to what they actually are. There is no cure for colour blindness. Visual aids and personalized identification methods can help colour blind people.

LONGSIGHTEDNESS

Longsighted people have the ability to see distant objects clearly and close objects less not so well. It is caused by a defect in the length of the eyeball. Prescription spectacles and contact lenses can correct long sightedness

SHORTSIGHTEDNESS

Shortsighted people can see close objects clearly and objects further away not so clearly. The shape and length of the eye causes this common defect. It can readily be corrected with special prescription spectacles and contact lenses.



TYPES OF VISION


PERIPHERAL VISION - What we see out of the corner of our eyes. While most of our vision is central we have the ability to see and detect changes within a panoramic range.

BINOCULAR VISION - Is when we receive images from both eyes. Our brain combines both these images into a single sharp image. The slight difference in angle in which each eye views an object produces full three-dimensional sight.
