Symptoms of cataracts include clouding or blurring of the vision, difficulty seeing at night, sensitivity to light and halos around lights, according to Mayo Clinic. Colors may fade or yellow. As the condition becomes worse, the patient may experience a frequent need to change his prescription eyewear.
Initially, the individual with cataracts may find changes in his prescription and improved lighting conditions improve his vision. However, as the cataract continues to grow, patients describe their vision as looking through a frosted glass, states Mayo Clinic.
Cataracts form on the lens of the eye, reports Mayo Clinic. They form due to injury to lens tissues. The thickened and less transparent tissue scatters the image as it enters the eye; it does not form a sharp image on the back of the eye and blurs the vision. Any changes in vision necessitate a visit to an eye care professional. Sudden vision changes require seeing an eye doctor immediately.
The only effective cataract treatment is surgery, explains Mayo Clinic. The patient and his doctor discuss the best time for the surgery, but most doctors recommend surgery when the cataract interferes with the quality of life. A delay in having the surgery does not increase the risk of recovering the patientﾒs vision after he has the procedure.
