Mapping The Eye: Lighting the Way to Clearer Vision

Eye exams are not just about testing your eyesight or determining the proper grade of your eye glasses or contact lenses. They concern your health, too, just as much as a visit to the doctor for a more regular check-up does. Eye doctors give these exams to detect whether you have certain diseases, helping to prevent or slow down its progression.

In evaluating your eyes through eye exams, the doctor looks for certain conditions such as refractive errors, ambylopia and strabismus. Refractive errors refer to nearsightedness, farsightedness and astigmatism. Ambylopia, also known as the lazy eye, is a kind of vision disorder in which an eye fails to see an image even with the aid of eyeglasses or contact lenses. Strabismus is described as a condition in which a patient is cross-eyed. The doctor also checks for early signs or symptoms of certain eye diseases such as glaucoma and diabetic retinopathy.

The eye exams the doctor performs also help in the assessment of your health in general. They can determine whether you have high blood pressure or high cholesterol or are diabetic. For instance, if an eye exam shows that your blood vessels in the eye are damaged, resulting in bleeding and swelling of the macula, then your doctor diagnoses you with diabetes.

The traditional conventional eye exam uses a phoropter, a device which allows an ophthalmologist or optometrist to put lenses in front of your eyes, changing them around and asking you which produces a clearer image for you. Improvements in eye exam Indianapolis technology, however, have led to the use of wavefront technology in place of the phoropter.

The use of wavefront technology has become important in performing eye exams Indianapolis. This technology can easily identify high-order aberrations such as coma, trefoil and spherical aberration that are not usually covered in conventional eye exams.

In a wavefront eye exam Indianapolis, an aberrometer where you rest your chin, peer into it, and focus your attention on a point of light, is used. In a matter of seconds, a wavefront travels through your pupil and into the retina, creating an aberration map of the eye. Then in mere minutes, data that contains the wavefront measurement of your eye is printed. If the wavefront is flat, then that means you have sharp vision, but if not then your vision will need correcting.
