Not all Retinas are created equal; similarly, not all lenses are created equal. The reason why you find such a big difference in lens prices is because there is such a big difference in lenses. At Sight N' Steps Ajax and Pickering locations, the only lenses we dispense for our patients are the ones made by either Essilor or Nikon. Essilor is the world largest eyewear lens manufacturer and Nikon we all know from the camera lenses that they are one of the top brand of lenses. Even then within the Essilor or Nikon catalogues, the only lenses we dispenses for our patients are the ones that have been extensively researched and been proven successful.
The result of all this effort on our part is improved vision for Sight N' Steps patients, less fatigue, no more eye strain, and none or significantly reduced blurry spots on your peripheral vision.
A slit lamp is a binocular microscope (or "biomicroscope") that your eye doctor uses to examine the structures of your eye under high magnification. It looks somewhat like a large, upright version of a microscope used in a science lab.
During the slit lamp exam, you will be asked to place your forehead and chin securely against the rests on the front of the instrument and your doctor will begin by examining the structures of the front of your eyes — including your eyelids, cornea, conjunctiva, iris, and lens.
Stereopsis is the term used to describe eye teaming that enables normal depth perception and appreciation of the 3-dimensional nature of objects.
In one commonly used stereopsis test, you wear a pair of "3D" glasses and look at a booklet of test patterns. Each pattern has four small circles, and your task is to point out which circle in each pattern looks closer to you than the other three circles. If you can correctly identify the "closer" circle in each pattern, you likely have excellent eye teaming skills that should enable you to experience normal depth perception.
Your eye doctor may perform this test early in the eye exam to obtain an approximation of your eyeglass prescription.
In retinoscopy, the room lights will be dimmed and you will be asked to focus on a large target (usually the big "E" on the eye chart). As you stare at the "E," your eye doctor will shine a light at your eye and flip lenses in a machine in front of your eyes. This test estimates which lens powers will best correct your distance vision....
