THE SYMPTOMS AND SIGNS
Understanding the symptoms will help you identify the first signs of one developing and ensure you seek out the advice of an optician. They usually start out very small, and initially have little effect on your vision.
The most common indicators of a cataract include blurred or misty vision, or small patches or spots where your vision is less clear. It may be like having a smudge or cloudy patch on your glasses.
You may also: Find lights too bright or too glaring, either from lamps, the sun, or car headlights;Find it harder to see in dim light; Experience a brown or yellow tinge to your eyesight;Find colours look faded and less clear;Experience double vision; See a circle of light (halo) around bright lights.
Cataracts are not usually painful, and rarely cause irritation or redness. They are only associated with other symptoms in extremely advanced cases.
TYPES OF CATARACTS
Symptoms can be affected by the exact type of cataract you have and some signs may show sooner than others. Different types include:
- A nuclear cataract- This is usually associated with ageing, and form deep in the nucleus (centre) of the lens.
- A sub-capsular cataract – This is associated with people who have diabetes or have taken high doses of steroids. It forms in the back of the lens.
- A cortical cataract- This occurs in the lens cortex and is characterised by peripheral clouding which works its way toward the centre of the lens.
The development of a nuclear cataract may actually temporarily improve your near vision for a short period of time, but this will soon worsen as the condition progresses. A sub-capsular cataract on the other hand might not show any symptoms whatsoever until it’s at an advanced stage.
In their initial stages cataracts can be treated with stronger prescription glasses and an adjustment in the brightness of lights. However, these are only temporary measures, as the condition will gradually get worse. Permanent treatment will eventually be required.
Surgery is the only effective treatment as the lens in the eye will need to be removed and replaced. If your loss of vision begins to affect daily activities, this will likely be the recommendation of your optician or ophthalmologist.
