Much like a camera lens, the natural lens of your eye focuses light onto the retina to create clear images. When cataracts develop, this once-transparent lens becomes cloudy, leading to blurred or impaired vision.

Eye strain, or eye fatigue, occurs when your eyes become overworked due to prolonged focus on bright screens, close-up tasks, or extended periods of concentration. Just like any muscle in the body, the muscles surrounding the eyes can become fatigued from overuse, leading to discomfort and vision issues.

Glaucoma is a progressive eye condition that damages the optic nerve, leading to vision loss—primarily affecting peripheral vision. This means you may see clearly in the center of your vision while gradually losing sight in the outer areas. Because glaucoma develops slowly, many people don’t realize they have it until significant vision loss has occurred.

Diabetic retinopathy is a serious eye condition that develops as a complication of diabetes. It occurs when high blood sugar levels damage the blood vessels in the retina, the light-sensitive tissue at the back of the eye. If left untreated, diabetic retinopathy can lead to vision loss and, in severe cases, blindness.
