SEIKO Wrap Tech ThinIntroducing SEIKO Wrap Tech Thin single vision lenses for wrap style (highbase curve) eyewear. Designed to solve the problems associated with currenthigh-base prescription eyewear, Wrap Tech Thin lenses apply SEIKOInternal Free-Form technology to deliver the best balance of clear visionand cosmetic appearance.The demand for highly curved prescription frames in clear and sunglassesis increasing, as wearers look for high tech fashions along with comfortand advanced optics. Some of the benefits are:• High fashion design• Wide peripheral view• UV protection from the side, and a barrier to dust and wind• Decreased backside reflectionsConventional high-base wrap eyewear designs create asymmetry betweenthe nasal and temporal sides of the lens. This results in power error andastigmatism across the entire lens surface, which causes uncomfortable,distorted, and over or under corrected vision throughout both eyes. Prismerror is also created due to the angle between the line of vision and thelens optical axis, resulting in eye fatigue and visual discomfort.ConventionalFrame GeometryTypical WrapFrame GeometryViewing Line and Lens AxisPrism ErrorNasalTemporalNasalTemporalConventionalHigh Base CurveWrap Tech Thin lenses use a free-form panoramic, aspheric and asymmetricdesign that corrects power error and astigmatism across the lenssurface. The aspheric design is optimized for each meridian, creating a50mm wide ‘sweet spot’ of comfortable, natural vision centered at thefitting point.

• Internal Free-Form technology achieves the most aberration-free vision in high base lenses• Advanced design corrects power error, marginal astigmatism and induced angle prism• Lightweight and thin 1.67 high-index material enhances fashionable curved frames• Wide, comfortable and precise vision to the periphery• Advanced, Seiko high-index hardcoat provides outstanding protectionConventional Aspheric Design(without cylinder)Uniform Design50mmSweet SpotPanoramic Asymmetricand Aspheric designFrame-SpecificPrismatic CorrectionNasalSideSpherical DesignImprovement of Power ErrorNasalSideWrap Tech ThinAspheric design is optimizedfor each meridianTemporalSideTemporalSideA frame-specific correction is calculated to compensatefor the prismatic error that occurs due to the differencebetween the optical axis and the line of vision. Advancedfree-form style-thinning technology is then incorporatedto produce the thinnest lenses possible.Wrap Tech Thin lenses are made from 1.67 high-indexplastic.

Brown and gray polarized lenses reduceblinding glare when driving or when outdoors in brightsunlight.• SEIKO Sportswear Transitions SOLFX lenses are a perfectchoice for people who demand dynamic sunwear.Their light green-gray G15 color tint indoors changesto 85% sunglass shade outdoors when exposed to UVlight. This green-gray color space allows true color recognition,providing the wearer with clearer, more vivid“color enhanced vision.”• Mirror coatings and anti-reflective coatings are alsoavailable on all Wrap Tech Thin lenses.When ordering, it is important to supply accurate measurements,especially frame wrap angle. Consult theWrap Tech Thin Order Form for instructions and measuringguides and always be sure the lenses will cut out correctly.To accommodate larger wrap-style frame shapes,Wrap Tech Thin lenses are automatically decentered5mm or 10mm, giving the lens an effective diameter of80 or 85mm.color enhanced vision
