As we get older, the normal lens of the eye deteriorates in one of two ways. The first sign of worsening often begins in our 40’s when the natural lens of the eye becomes less flexible and we slowly lose our aptitude to focus from far to near and back again.
Bifocal glasses, reading glasses or bifocal contact lenses are frequently used to correct this disorder. If you are living in Sydney then you can find best laser eye surgery sydney.
The second sign of deterioration is the formation of cataracts, which is a clouding of the eye’s obviously clear lens. The natural lens focuses light rays on the retina to produce a sharp image of what we see. When the lens becomes overcast, light rays cannot pass through it effortlessly, and vision is blurred. This is a visual impairment that often affects us in our 60’s, 70’s or 80’s.
How is a cataract treated?
Operation is the only way a cataract can be removed. However, if symptoms of a cataract are not bothering you very much, surgical treatment may not be needed. Sometimes a simple change in your eyeglass prescription may be helpful. No medications, dietary supplements or exercises have been shown to prevent or cure cataracts.
When should cataract surgery be performed?
Surgical treatment should be considered when cataracts cause enough loss of vision to interfere with your daily activities. You must choose if you can see well enough to do your job, drive safely, and read or watch TV in comfort.
