20D LENS

Features

• Imported glass with multiple coatings provides clear image and broad vision.
• Providing Corrected field curvature and aberrations. This lens will deliver an excellent retinal image.
• The image provided by this lens will unsurpassed clarity over the entire field of view.

Design

■ Each lens incorporates state of the art aspheric computer generated design and manufacturing techniques.
■ These eight lenses also receive an exclusive hydrophobic coating, which repels water, smudges and dust, making cleaning easier.

Technique

■ Commonly known indirect ophthalmoscopy techniques using either the slit lamp or binocular indirect ophthalmoscope should be used.
■ The silver ring on the lens holder should be held toward the patient’s eye during examination. It is important to recognize that this unidirectional design provides the best image quality possible.
■ Keep the lens centered on the patient’s pupil.
■ Hold the lens far enough from the patient’s eye so that the retinal image is the same diameter as the lens.
■ Keep the illumination source as dim as possible to minimize reflections and loss of image contrast.

Cleaning

Clean with alcohol wipe.
