What are the characteristics of cataract

summary

Cataract is more common in people over 40 years old, and the incidence rate increases with age. All kinds of reasons, such as aging, genetic, local nutritional disorders, can cause lens metabolic disorders, leading to lens protein degeneration and turbidity, which is called cataract. At this time, light is blocked by the turbid lens and cannot be projected on the retina, resulting in blurred vision. However, cataracts are easy to see. Here are some features of cataracts to help you understand.

What are the characteristics of cataract

Symptom one: overlapping of what you see. The contrast sensitivity decreased under strong light, and glare was produced under night light

Symptom 2: monocular diplopia or diplopia, iridescence, photophobia and glare can also appear. Generally speaking, the development process of symptoms is slow, but patients with systemic diseases or eye local diseases will be earlier and progress faster.

Symptom 3: in addition, some people wear presbyopic glasses for a long time, and sometimes they can see near objects clearly when they don't wear presbyopic glasses, which is also an early signal of cataract.

matters needing attention

1. After suffering from cataract, people often show that the lens cortex is completely turbid, the appearance is diffuse milky white, the lens expansion completely subsides, the anterior chamber depth returns to normal, and the iris projection does not exist. 2. Cataract patients should not use copper cookers to boil water to make soup, because copper cookers can dissolve some trace elements of copper, destroy the body's vitamins and disadvantageous to eliminate cataract.
