A cataract is a clouding of the lens in the eye that affects vision. Cataracts can be related to ageing or excessive exposure to UV, causing blurred vision.


Lens and the Retina
The lens is the clear part of the eye that helps to focus light, or an image on the Retina. The Retina is the light-sensitive tissue at the back of the eye. In a normal eye, light will pass through the transparent lens to the Retina. On reaching the Retina, light changes to nerve signals that are sent to the brain. The Lens must be clear for the Retina to receive a sharp image. If the lens is cloudy due to cataract, the image seen will be blurred.


Signs and Symptoms:

  • Dulled colour vision
    Blurred/cloudy vision
    Difficulty with glare for example night driving
    Frequent changes in your prescription
    Increase in short-sightedness
    Double vision in the eye affected



During modern Cataract surgery, the natural lens is removed and replaced by an Intraocular Lens. Cataract position and the severity can determine how much your vision is affected. The correct time for Cataract surgery is when you feel the risks of the operation are outweighed by the benefits.


Action taken
Cataracts are usually an age-related condition and sometimes may not be avoided, but will be treated. However, it is beneficial to know how you can prevent your sight from worsening to the stage where it is untreatable. The Optometrist checks for any early development and will advise of any signs.
