How are cataracts and presbyopia different?

People get old before they get old, and as we get older, it is inevitable that we will be "faint-eyed". When I was young, my eyesight was very good. When I was in my 40s, I started to see blurry near distances, and I felt that the focus was out of focus, and I was easily fatigued and labored. On the contrary, some people who are short-sighted may not have this kind of reaction when they are in their 50s or 60s. Does presbyopia favor people with good eyesight? Different from refractive errors such as myopia, hyperopia, and astigmatism, presbyopia is a physiological decline in accommodation. If the eyes are compared to a camera, the appearance of presbyopia is the process of the camera's focusing function diminishing. The degree of impairment of accommodation varies from person to person, but is not favored in people with good vision. The reason why everyone thinks that people with myopia are presbyopic late is because their own degree of myopia makes up for the lack of adjustment when they look near. When the degree of presbyopia exceeds the degree of myopia, discomfort such as difficulty in seeing near will also occur. With age, cataracts also appear. In the process of presbyopia, the transparent lens in our eyes will gradually become cloudy, resulting in the inability of light to enter and affecting vision. This is cataract. The impact of cataract on our life is far greater than that of presbyopia. As a blinding eye disease, cataracts not only cause blindness themselves, but also may induce other eye complications during the development of the disease, resulting in visual impairment. How are cataracts and presbyopia different? [Presbyopia] blurred vision near vision, but not affected by far vision. Generally, it occurs after the age of 40 without causing blindness. It can be corrected by glasses or surgically treated. [Cataract] Both near vision and far vision are blurred. Cataracts may appear in all age groups, such as: congenital Cataracts, cataracts advanced to young and middle-aged due to high myopia, and age-related cataracts after the age of 60 can only be treated by surgery. Currently, refractive cataracts are surgically removed by removing the cloudy lens and implanting a functional intraocular lens at the same time. , such as the trifocal intraocular lens, which can correct myopia, hyperopia, astigmatism, and presbyopia while treating cataracts, allowing middle-aged and elderly friends to get rid of the trouble of glasses and live a relaxed life. Whether it is cataract or presbyopia, if you have eye discomfort and affect your life, you should go to a regular hospital for related examinations and treatment. Don't be superstitious about some folk remedies, so as not to delay the disease.
