PROTECT YOUR EYES, PROTECT YOUR VISION.

 Is your vision blurry?

Cataracts are common as you age – but that does not mean you just sit back and wait for your eyesight to deteriorate. Cataracts can affect you by limiting the activities you can enjoy. At the worst case, cataract can lead to blindness.


What are cataracts?



Cataracts are cloudy areas in the eye’s lens (lens helps to focus light or an image on the retina). A normally clear lens allows light to pass through to the back of the eye, so that a person can see well-defined images. If part of the lens becomes opaque (cloudy), light does not pass through easily and the vision becomes blurry – like looking through cloudy water or a fogged-up window. In many cases, cataracts are age-related and appear in later life stages.



Age-related cataract occurs in two ways

1. When the ultraviolet light passing through the lens of the eyes, it produces free radicals that damage the proteins in the tissue. This causes the proteins clump together in the lens, causing it to become cloudy.

2. The breakdown of proteins in the lens leads to accumulation of a yellow-brown pigment that clouds the lens.

Risk factors for age-related cataracts include
  • Aging (Appear in your 40s, 50s, 60s onwards)
  • Family history (Cataracts tend to run in families)
  • Long term diabetes
  • Long term exposure to bright sunlight
  • Previous eye inflammation
  • Long term use of certain medications (eg statin and steroid)
  • Smoking IS YOUR VISION BLURRY?
Symptoms

Typically no symptoms are experienced until cataracts have grown large enough to interfere significantly with the passage of light through the lens.

Five common symptoms of age-related cataracts are
  • Blurry, cloudy vision
  • Vision may be affected by small spots or dots
  • Vision gets worse when lights are dim
  • Reading becomes very difficult, and eventually impossible
  • Double vision
Prevention of cataracts
  • Say goodbye to smoking
  •  Load up on antioxidants
  • Wear sunglasses to block UV rays
  • Keep diabetes under control if you are diabetic
  • Regular exercise
Treatment

With cataract surgery, the eye’s cloudy natural lens is removed and replaced with a clear artificial lens implant called an intraocular lens (IOL). Cataract surgery is often performed as an outpatient procedure. After the surgery, the doctor usually places a protective shield over your eye. Your vision is a precious asset, and one that is vulnerable to the effects of aging.

There are things you can do to protect your eyes. It’s never too early or too late to start protecting your vision.
