These are the common symptoms of cataract:
• Painless blurring of vision or cloudy vision
The image will appear cloudy and the image will get worse gradually. Cataract doesn't cause painful red eye unless it is associated with another cause such as glaucoma. Any sudden loss of vision is not related to cataract and you should visit your eye doctor as soon as you can.
Some people especially young patients will complain of blurred vision even with mild cataract while others like old people will not complains of blurred vision even if they have moderate or even severe density cataract.
