What does NSC mean in OPTOMETRY

The main symptom associated with NSC is blurred vision, which can range from mild to severe. Other symptoms may include difficulty seeing at night, increased sensitivity to glare and bright lights, double vision, faded colors, poor contrast between colors, and difficulty focusing on objects up close.

The exact cause of NSC is unknown but it occurs when the lens's nucleus hardens due to changes in its proteins and fibers. As these changes progress, they obscure light passing through the eye leading to a gradual loss of vision.

Diagnosis usually involves a comprehensive eye exam including an analysis of your medical history as well as visual acuity tests to measure your distance and near vision. Your doctor may also use other tests such as a slit lamp examination or ultrasound scans for further evaluation.

Treatment options include lifestyle changes such as wearing protective eyewear and avoiding direct exposure to sunlight as well as prescription medications or surgery if necessary. Surgery generally has a high success rate with most patients regaining some degree of their lost vision after the procedure.
