Once your lens hardens, light is blocked and scattered as it passes through the lens. Since light is not focused on the retina, vision becomes blurry. A person with a cataract has blurred vision from all distances, may it be near or far.
A person with a cataract will notice that they can not see sharp images. They will also have difficulty seeing fine details.
A person with developing cataracts might have difficulty reading. An average person can read a size 11 text at 35cm. This is usually the comfortable distance for reading a book. Normally a person can view a size 32 text at 1.5-meter distance, which is usually the size of texts in posters.
A person with cataracts might find themselves having difficulty reading at any distance. Even if they read text close to their face, this might not help them in reading. Vision usually improves only when they squint. Squinting helps in focusing light into the retina.
A person with a cataract will have difficulty distinguishing colors in their vision. When the lens hardens, it becomes brownish or yellowish. The discoloration in the lens also translates to yellowish and brownish hues in vision. It would feel like you are wearing yellow or brown-tinted glasses. Over time, blues and purples also become more indistinguishable.
Difficulty seeing at night
People with cataracts will have difficulty seeing at night. Because light does not pass through the eye effectively, seeing in places where light is limited becomes a struggle.
Even if there is no or minimal light, a person with healthy eyes can still see shapes and silhouettes once they have adjusted to the darkness. People with cataracts tend to have difficulty seeing in the dark and adjusting to the darkness.
Need for brighter light
Cataracts hinder light from entering the eyes. People with cataracts tend to need more light when they are doing activities such as working on their desk, reading, or even day-to-day tasks such as cooking and cleaning
Frequent changes in the lens prescription
If a person has been changing his lens prescription too often, probably more than once in a year, then this could be a sign that they are developing cataracts.
A person with cataracts may develop myopia or nearsightedness. If the person is already nearsighted, to begin with, their prescriptions may go higher. On some occasions, patients with cataracts can also develop hyperopia or farsightedness.
If a person is developing cataracts, they will notice that they are seeing two of one thing. They may also see distorted images in their vision. It would seem that they are looking at something through a veil or images tend to look ghost-like. Double vision happens usually with just one eye, the eye affected by a cataract.
