Cataract Awareness Month

Cataracts are the leading blindness among older adults in the world, but can affect young and old.

What is a Cataract?

A cataract is a clouding of the eye’s lens, which blocks the passage of light into the eye. The lens of the eye is located behind the pupil and the coloured iris, and is normally transparent. The lens helps to focus images onto the retina – which transmits the images to the brain.
Your vision may become blurry or dim because the cataract stops light from properly passing through to your retina.

Why do cataracts form?

Cataracts are probably caused by changes related to aging.
As we grow older, the old cells in our eye’s lens build up and block light as it tries to pass through. The end result is cloudy vision.
Other factors that can cause the formation of cataracts are: eye infections, some medicines (such as steroids), injuries or exposure to intense heat or radiation. Too much exposure to non-visible sunlight (called UV or ultraviolet light) and various diseases, such as diabetes or metabolic disorders, may also contribute to cataracts forming.

Everyone who gets a cataract experiences it differently, but a person with a cataract commonly experiences cloudy or blurry vision.
Light may cause a glare, seem too dim or too bright. It my be hard to read or drive, especially at night. If you have a cataract, you may see halos around lights such as car headlights that make it hard to focus clearly. Colours may not seem as bright as they used to be or you may have to change your spectacles prescription often.

IF YOU NOTICE ANY OF THESE CHANGES, MAKE AN APPOINTMENT TO SEE YOUR OPTOMETRIST.
WE CAN IDENTIFY THE CONDITION AND REFER YOU TO AN EYE SPECIALIST.
