Are you concerned about your eye health and do you live in Derry or Londonderry? Consider scheduling an appointment with an eye doctor to check for common vision problems like astigmatism. Astigmatism is known as a refractive error because it affects the way the eye bends light. It is possible to have astigmatism and another refractive error, such as nearsightedness or farsightedness. Fortunately, your eye doctor can recommend eyeglasses or contact lenses to correct astigmatism.
