Cataracts are characterized by a clouding of your eye’s lens which is located at the back side of the iris and the pupil. As you age, cataract develops when strands of protein form on this lens which can interfere with the clarity of images that you see.
Cataract is one of the most common eye problems responsible for vision loss that affects people aged above forty. Your risk for getting cataracts increases as you get older. It is also one of the main causes for blindness globally.
Causes for cataracts can be attributed to frequent exposure to ultra violet rays, deficiency of vitamins, use of certain medications and eye trauma or eye diseases.
One of the ways you can take an active role in promoting your health is by knowing about cataract symptoms. Doing so will help create useful awareness and enable you to react positively in dealing with this eye condition.
What are the Symptoms of Cataracts?
The symptoms for cataract are influenced by the location of cataract on the eye’s lens and the area it has covered, and whether it exists in one or both of your eyes.
It takes years for cataracts to develop, and this leads to gradual worsening of eyesight. Cataracts are painless and generally start in one eye but can affect both the eyes. Nonetheless, it is non-contagious and cannot spread from one inflicted eye to the other.
In the initial stages, cataracts form as a mild clouding on the lens which only has a slight effect on your vision. But as the cataract grows in size, it starts interfering with light that passes through the lens. Over a period of time, the cataract progresses and you may start noticing the following symptoms:
- Clouded, blurry vision
- Dim vision along with difficulty seeing at night
- Double vision
- Oversensitive to light or glare
- Halos start to appear around lights
- Frequent eyeglass or contact lens prescription changes
- Colors appear pale, washed out or faded
Changes in vision are a common cataract problem and you may experience glare or halos from natural or artificial light sources. As a result driving on the road at night becomes a difficult ordeal as a result of glare from vehicle headlights.
Colors may appear less intense and you may have problems differentiating shapes against a background. Over time, you may have difficulties reading.
Moreover, these symptoms can occur due to health problems other than cataracts such as diabetes or other eye illnesses. If you suspect having any of the above signs and symptoms of cataracts development stated above, a visit to your optometrist can help settle your vision related doubts and queries.
Additionally, people aged seventy years or above are more prone to have cataracts that can affect and deteriorate their vision considerably. Patients with advanced cataracts have chalky or yellowish pupils (which are normally black) and the vision diminishes to an extent where the patient finds it very difficult to see objects, even in bright environments.
Cataract is an easily treatable eye condition and most people operated with cataract surgery have reported better vision. It is a safe and effective surgical procedure that replaces the cataract affected lens with an artificial lens.
