[뉴스토마토 동지훈 기자] Among various body organs, the eyes directly exposed to the outside are one of the body parts that are vulnerable to UV rays. UV rays reach the surface of the earth regardless of the season throughout the year, so even the cool autumn sunlight is full of UV rays. If strong UV rays continuously penetrate the eye, there is a high risk of cataracts, so you should be careful about cataracts even in the fall.
Cataract is a disease in which the lens in the eye becomes opaque and causes various visual disturbances. The lens of our eye can be compared to a camera. When a cataract develops, the transparent lens becomes cloudy and blocks light, making it impossible to focus, making objects appear blurry.
Cataracts are known to occur with aging, but they can also occur due to external factors such as strong UV exposure, smoking and drinking, and blue light from electronic devices. Patients with diabetes or high blood pressure may develop cataracts as a complication.
Cataracts often do not show any abnormal symptoms in the early stages. Due to the nature of the disease, symptoms do not appear in a short period of time and develop over many years.
As the opacity of the lens increases, the visual acuity deteriorates and glare symptoms appear. Diplopia, in which objects appear as multiple objects, may occur. In rare cases, the color of an object may look distorted, or pain may be felt as the pressure in the eye increases.
In the early stages of cataracts, drugs or eye drops can slow the progression of the disease, but the most reliable treatment is surgery. Surgery is mainly performed when there is a possibility of complications such as glaucoma, which increases intraocular pressure, or when a person feels uncomfortable in daily life due to decreased visual acuity. The operation is performed by removing the opaque lens and then inserting an artificial lens, and the recovery of the surgical site takes about 6 weeks.
Nam Ki-tae, an ophthalmologist at Korea University Ansan Hospital, said, “In the early stages of cataract development, a ‘second vision phenomenon’ in which myopia is temporarily corrected by improving the refractive power of the lens may occur. It is important to note that the phenomenon of double vision can occur, which rapidly declines and objects appear double.”
