Disclaimer:
Based on the values in your prescription, we try to recommend the lens that will give you the optimum vision correction and thinness of lens. We do not recommend more expensive high index lenses if we do not think it will result in a noticeably thinner lens, though you are free to choose any lens available. The recommended lens will always be clear.

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. The upper part of the lens is generally used for distance vision, while the lower part is used for near vision, with a flat 28mm line separating the reading segment.
Bifocal Flat Top 35mm	Bifocal lenses are used for distance and near vision correction with a separating line at the near vision / reading segment. The upper part of the lens is generally used for distance vision, while the lower part is used for near vision with a flat 35mm line separating the reading segment.
Bifocal RD 22mm	A Bifocal lens with a round 22mm reading segment - less visible in the lens.
Trifocal Flat Top 7x28	Similar to bifocals, except that the two focal areas are separated by a third middle area with intermediate focus correction with a 28mm line separating the reading segments on two parts.
