Cataracts are an eye condition that cause your vision to become cloudy and blurry. With cataracts, your eye’s natural lens will see blurred images, less colour, and haziness as the proteins of your lens break down. Normally, the lens focuses images clearly, so when a cataract is present, the lens focuses on the retina and blocks the light rays to pass through the lens. The retina is at the back of your eye. The retina is very sensitive to light because of its tissue lining. Cataracts usually occur when the proteins which make up the eye lenses begin to change their structure and get in the way of your vision.

Types of cataracts:

  • Age-related: Most cataracts are related to the aging process and they usually occur in the middle and upper ages.
  • Congenital: This type of cataracts is a genetic cataract. Sometimes we are born with cataracts, and its also possible for them to develop during childhood, usually within both of their eyes. Some congenital cataracts do not affect vision, but they still need to be removed.
  • Secondary: Secondary cataracts usually occur when other diseases are present in your body (for example diabetes). It is also common to see cataracts in people who use steroids.
  • Traumatic: Traumatic cataracts usually occur right after an eye injury or even a few years later. The main cause of traumatic cataract is an injury to one or both eyes.

Cataracts frequently happen within the normal changes to the amount of protein in your eye’s lenses caused naturally by age. From around 40 years-old, the proteins in the lens of your eye start to drop, and this change creates cataracts. If not treated, cataracts can become severe and increase the blurriness in the lens of your eye.

Like other allergies, hay fever can be hereditary. This means you may develop hay fever if members of your family also have allergies. It is also common for people with asthma or eczema to develop hay fever. Hay fever may result in immune system attacks from a harmless and typical substance within the environment.
