How does a Fresnellenswork

The purpose of the goggles is to disable the patient's ability to visually fixate on an object while at the same time allowing the examiner to adequately visualize the eye. This is done by using high-powered (+20 diopters) magnifying glasses with an illumination system. With such a high-powered lens, it is unlikely that the patient can adequately focus and visually fixate on an object to suppress nystagmus.[2]

Relay Lenses are used to extend imaging systems or invert images for use in a range of imaging applications including microscopy, inspection, or life sciences. Relay Lenses use arrays or imaging lenses placed behind eyepieces to extend the length of imaging systems, such as in microscopes, endoscopes, or where proximity to a viewed object is not feasible. Relay Lenses may also be used to invert an image behind the eyepiece of an imaging system for proper viewing. Relay Lenses are available in a wide range of options suited to a number of relay needs.
