Blurred vision, depending on the material gradually blurred, and sometimes feel the light around the aperture and the color of the object is not bright enough. If the cataract patient is driving at night, there will be a kind of opposite the car headlights too dazzling and feel uncomfortable or irritable feeling. But in general, early cataract symptoms of the development process is quite slow, and depending on the lens of the most turbid location and its development process
Abnormal color vision, cataract early because the lens absorbs more water and swelling, the epithelial cell gap increases and filled with droplets of water droplets, light through it will occur when the refraction and color halo, commonly known as rainbow.
What are the early symptoms of cataracts?
3, in front of the shadow
Early cataract, part of the lens opacity in the pupil area, in front of the location can be fixed, the shape of the same point or sheet shadow. It is caused by the vitreous opacity of the mosquitoes are different, the latter's shadow is moving, although the scope of activities is not large, but when the hidden, the shape of changeable.
4, day blindness or night blindness
Day blindness or night blindness, if the lens opacity first in the central part of the beginning, daytime light intensity, pupil shrink, the light into the eye blocked, resulting in day blindness; such as the lens opacity in the peripheral part of the evening dark light into the equatorial retina blocked, and Equatorial retinal rod-like cells are liquid-based vision, which will appear fluid blindness, which is one of the early symptoms of cataracts.
5, eye flowers to reduce
Elderly usually need to wear reading glasses to read the newspaper, but they will suddenly find themselves do not need to wear presbyopic glasses see also very clear, and some old happy, in fact, this is not a good sign , This is because the initial cataract early, the lens convexity increased, refractive point near the point of change, is one of the early symptoms of cataracts.
