Cataracts are often misunderstood as a film developing over the eye, but in reality, they are characterized by a cloudiness that develops within the lens itself. This cloudiness interferes with the transmission of light to the retina, resulting in diminished clarity of vision.
The formation of cataracts is frequently associated with the natural aging process, compounded by prolonged exposure to ultraviolet (UV) light. Therefore, wearing high-quality sunglasses and a brimmed hat when outdoors is crucial for mitigating the progression of cataracts by minimizing UV exposure.
In addition to aging and UV exposure, cataracts can also result from traumatic injury or certain medical conditions. Understanding these risk factors and taking proactive measures to protect eye health is paramount in preserving vision and overall well-being.
Just like ageing, cataracts cannot be reversed but fortunately, cataracts can be removed surgically and cataract surgery is the most common operation performed in the world today. It is most commonly performed under local anesthesia and normally does not require overnight stay at the hospital/clinic. Improvement in vision can often be noticed after just one or two days but generally takes up to two to three weeks for the eye to recover fully after which new glasses may need to be prescribed.
There is no sure way to prevent cataracts but long-term exposure to UV (ultraviolet) light is believed to induce them. Wearing sunglasses and a wide-brimmed hat in sunlight will decrease your exposure to UV light.
