Single Vision	Single vision lenses are prescribed if you need correction for one field of vision, either for distance, intermediate (computer), or items up close (near vision). Single vision has the same optical focal point or correction over the entire area of the lens.
OmniLux® NAL® NEW!	OmniLux® HD Digital is a new concept in multifocal vision. It is not a bifocal, trifocal or progressive (PAL) lens. OmniLux® NAL® is the World’s First NAL® (Natural Accommodation Lens) lens. Lenses provide a Single Vision viewing experience with continuous, sharp, natural vision at any gaze from distance to near without waves or distortions. There is no adaptation period. Read more...
Progressive	LUXVIEW® HD Digital - Provide a smooth transition from distance correction to near correction, eliminating segment lines and allowing clear vision at all distances, including intermediate.
Bifocal Flat Top 28mm	Bifocal lenses are used for distance and near vision correction with a separating line at the near vision / reading segment.
