The Most Common Symptoms of Cataract
The most common causes of blindness for people over the age of 40 are cataracts. Worldwide, there are more people with cataracts than there are of other major eye diseases like glaucoma and diabetic retinopathy. As Advanced Vision Care and other experts noted, there are several symptoms you should not ignore:
A cataract is an eye condition characterised by the clouding of the eye. In its advanced condition, the cataract can be seen as a whitish or yellowish disk covering the lens. The cloudy disk results in cloudy vision. This makes it difficult to read or drive a car at night. It may limit the ability to see clearly.
Cataracts develop slowly and do not have any negative effect on the eyesight during its early stages. It may even improve eyesight, as it forms a thicker lens. However, this advantage disappears as the cloudiness becomes more evident. Initially, eyeglasses and better lighting may help improve vision. However, this worsens as the cataract develops as a cloudy disk. When that happens, cataract surgery would be needed to reverse the impaired vision.
As the cataract develops, its symptoms become more apparent. Besides the clouding of the eye, there are other symptoms that revolve around a person’s degrading eyesight.
Vision becomes dim, blurred, or clouded. This results in increased difficulty with night vision. There is a need for better lighting for reading and other activities. It also results in the poor distinction of colours due to fading or yellowish colours. There is increased sensitivity to light and glare and sometimes, lights are seen with halos around them. Double vision in one eye could also happen. As such, the person may feel the need to frequently upgrade the prescription for eyeglasses and contact lens.
The cloudy disk starts at the rim of the eye’s lens. This soon develops into a full disk and continuous to be more cloudy. The cloudiness usually results in the above symptoms. The whitish disk is easily more evident than other symptoms.
