Refractive Errors

Over 120 million people in the United States wear eyeglasses or contact lenses to correct refractive errors, such as nearsightedness, farsightedness, or astigmatism. These vision disorders affect the cornea and are the most common of all vision problems in the United States.

Refractive errors occur when the curve of the cornea is irregularly shaped, either too steep or too flat. When the cornea is correctly shaped, it bends, or refracts light on the retina with precision. However, when the curve of the cornea is irregularly shaped, the cornea bends light imperfectly on the retina. This has a negative affect on your vision.

Healthy Living

Maintain a healthy weight. Being overweight or obese increases your risk of developing diabetes and other systemic conditions, which can lead to vision loss, such as diabetic eye disease or glaucoma.
