Reasons for Cataract
A cataract is the clouding of the lens in your eye which causes blurred or hazy vision. Ageing is one of the most common cause for cataracts other reasons may be eye injuries (Trauma), disease and long term medication of some drugs.
How a Normal Eye Works ?
The human eye functions in much the same way as a camera. Light passes through the lens of the camera and is focused on the film.
Your eye works in a similar, but more complex manner.
Your eye also has a lens. But instead of film, the image forms on the retina, which is at the back of the eye. Normally, the lens is a clear, transparent structure through which light can freely pass and focus on the retina.The retina responds to the image and sends signals to your brain, creating an instant picture, which changes as your view changes.
How a Cataract Eye Affects Your Vision ?
Light from an object is broken up as it passes through a cloudy, discoloured lens, causing the image to be blurred and dull.
Symptoms of Cataract
There are Several Symptoms to Indicate Cataract
An early sign is increasing glare from strong sunlight or bright lights at night. This may become quite bothersome and you may notice halos around different light sources such as car headlights.
Colours that are normally bright and vibrant, may appear faded and washed out-especially greens and blues. And most noticeably, your vision will become blurred and hazy, making it difficult to read small print or perform other tasks.
If you experience some or all of these symptoms it is time for you to visit an ophthalmologist.
Better Than Ever
Cataract surgery has undergone tremendous technological advances since the days of your parents or grandparents. This year, millions of patients will choose to have both their vision and their lifestyles restored, thanks to this life-changing medical procedure.
The good news is that you’ve encountered cataracts at a time when intraocular lens technology has taken a giant leap forward. No longer is the objective simply to restore your distance vision with a monofocal IOL. Today, the goal is to enhance your vision with an IOL that may provide you with a full range of vision, thus minimizing your dependence on glasses, including reading glasses or bifocals.
Once you understand what a cataract is, how it will be removed, and how your vision may be improved with the ACRYSOF ReSTOR IOL, your concern about your diagnosis could actually turn into excitement.
How Cataracts Develop
A cataract is a clouding of the natural lens inside your eye. This lens, located behind the iris (or colored part of the eye) works just like the lens of a camera-focusing light images on the retina, which sends the images to your brain.
The human lens, made mostly of protein and water, can become clouded – so clouded it keeps light and images from reaching the retina. Eye injury, certain diseases, or even some medications can cause the clouding. But, in over 90% of cases, clouding is caused by the aging process. A cataract is not a “film” over the eye, and neither diet nor lasers can make it go away. The best way to treat a cataract is to remove the old, clouded lens and provide a replacement.
A cataract can be the reason sharp images become blurred, bright colors become dull, or seeing at night is more difficult. It may also be why the reading glasses or bifocals that used to help you read, or do other simple tasks, no longer seem to help. Unfortunately, cataracts can’t be prevented, but removing the cataract and replacing it with an artificial lens can restore your vision and in many ways, significantly improve your quality of life. The time to have your cataracts removed is when the quality of your vision begins to put limits on your activities and enjoyment of life.
