During your eye examination for an eyeglass prescription, your eye doctor may perform a retinoscopy to obtain an approximate glasses prescription. During a retinoscopy, the lights will be dimmed in the room, and you will be asked to focus on an eye chart. As you stare at the eye chart, your optometrist will shine a light into your eye while flipping different lenses back and forth in front of your eye. Based upon how the light reflects from your eye, your eye doctor can estimate the lens power needed to correct your distance vision.
During your comprehensive eye exam at Philip E. Stein, OD, your eye doctor may also use the refraction test to determine your exact eyeglasses prescription. During refraction testing, an instrument known as a “phoropter” is placed in front of your eyes, showing you a series of lens choices. Depending upon your answers during the testing, the lens power will be fine-tuned until the perfect prescription is determined. Refraction can help determine farsightedness, nearsightedness, astigmatism and even presbyopia.
Both autorefractors and aberrometers can be used to estimate a patient’s eyeglasses prescription automatically. Both devices require you to rest your chin, stabilizing your head while you look into the device.
