One of the most popular tests for the eye that determines the best lens prescription for the patient is the refraction exam. It is typically performed using an instrument called a phoropter.
It replaces the glasses and lenses that are worn normally and allows professionals in the field of the eye to alter the amount of refraction provided through the lens.
This procedure, in conjunction with a reading diagram, provides any suitable reading regarding the prescription of lenses for those who are either Nearsighted or Farsighted but might not provide an answer to the root of the issue.
This is generally the most simple and can be completed continuously to assess the need for adjustments to the effectiveness of the vision issue.
Another common exam eye specialists use drops for the eyes that expand the pupil. The pupil inside the eye controls the amount of light that enters to avoid problems for the remainder of the eyeball.
As pupils expand, Optometrists can look directly into the eyes, and additional tests are performed.
