A cataract is a clouding of the normally clear lens of the eye. It can be compared to a window that is frosted or "fogged" with steam. Common symptoms of cataract include:
• Painless blurring of
vision
• Glare, or light sensitivity
• Frequent eyeglass prescription changes
• Double vision in one eye
• Needing brighter light to read
• Poor night vision
• Fading or yellowing of colors
The amount and pattern of cloudiness within the lens can vary. If the cloudiness is not near the center of the lens, you may not be aware that a cataract is present.
How often do I need an eye test?
Optometrists recommend that you should have an eye test at least every two years.
Prevention is better than cure
Eye problems may not be obvious to you early on, especially as the brain adjusts quickly to altered vision. The sooner a problem’s identified, the better it can be treated.
What are the potential benefits?
The right lenses can make life much easier – and stop vision getting worse. Early diagnosis can also prevent glaucoma, which otherwise causes irreversible blindness. And in children, it’s important to correct squinting before it becomes permanent after the age of eight.
Look after your eyes, look after yourself
Examining the eye reveals general health problems such as high blood pressure, neurological issues and diabetes.
What can I go to my optometrist about?
Optometrists are qualified to deal with any problem you might have with your eyes.
See your optometrist about anything from blurred or diminished vision to soreness and styes.
