In general, myopia only affects the vision of people who cannot see far, but if high myopia also has other complications, cataract caused by myopia is one of them. The specific manifestations are as follows: 1. iridescence: when looking at lights, colored halos appear.
2. Blurred vision: Cataract patients gradually blur their vision and sometimes feel that an aperture appears around the light as well as the color of objects is not bright enough. This development process is related to the degree of cloudiness of the crystal, and generally cataract patients will have different degrees of blurred vision. In general, however, the progression of symptoms is quite slow and depends on the location of the most cloudy lens and its progression.
3. Appearance of double vision: When looking at something, sometimes double vision or overlap can occur. A dotted or lamellar shadow with a fixed position and constant shape may appear in front of the eyes.
4.Reduced degree of presbyopia: Older people who originally have presbyopia may suddenly find that the degree of presbyopia decreases. In fact, this is not a good sign, which is one of the early symptoms of cataract because of the increase of lens convexity and the change of refractive proximal point when the cataract first occurs.
5.Dark shadows appear in front of the eyes: When there are fixed, unchanging dark shadows in front of the eyes, you need to pay attention to whether they are cataracts. We should pay attention to distinguish it from mosquito flying.
