These carefully crafted optics offer clear visuals from the center to periphery while being significantly flatter and thinner to improve overall aesthetics. An industry first, these innovative standard single vision lenses will certainly benefit both eyecare professionals and their patients alike.<\/p>\n\n\n\n<p>Globally, 75% of people who wear eyeglass lenses purchase single vision lenses.[1] These are often stock lenses due to their low cost and speedy delivery for both the eye care professional and patient.  In comparison to freeform-optimized lenses, standard single vision lenses are unable to unlock the full potential of precision. ZEISS ClearView lenses are engineered to give you many of the same benefits of freeform-optimized single vision lenses, but with the cost benefit of a standard single vision lens.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>&#8220;Innovation is at the core of the ZEISS brand, and we are transforming the standard single vision lens market by bringing many aspects of freeform lens design to the single vision lens category in both surfaced and stock&#8221;<\/p>\n\n\n\n<p><\/p>\n<cite>Jens Boy, President ZEISS Vision Care North America<\/cite><\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-zeiss-clearview-benefits\">The ZEISS ClearView Benefits<\/h2>\n\n\n\n<p>ZEISS ClearView lenses offer, on average, a three times larger zone of excellent clear vision and provide the wearer with more clarity from the lens center to the periphery.

The lens power is typically measured from the middle of the lens with vision clarity and optical performance across the entire lens being often neglected. Whether a stock FSV or SV surfaced lens, the truth is that traditional SV lenses do not offer superior peripheral optics. With the restrictions of ordinary SV lens designs, the ambition to make them flatter and thinner further compromises their optical performance particularly in the periphery of each lens.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"615\" height=\"230\" src=\"https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2023\/01\/peripheral-optics.png\" alt=\"Typical single vision designs are thicker than ClearView\" class=\"wp-image-7613\" srcset=\"https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2023\/01\/peripheral-optics.png 615w, https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2023\/01\/peripheral-optics-600x224.png 600w\" sizes=\"auto, (max-width: 639px) 98vw, (max-width: 1199px) 64vw, 615px\" \/><figcaption class=\"wp-element-caption\"><sup>Figure 1.

The answer is found within the design of the lens itself. While multiple forms can be used to obtain a central power for any given lens, different designs lead to varied aesthetics and wearing comfort, as well as having a massive influence on optical performance &#8211; especially in the lens periphery. Therefore, by optimizing lens design complexity (Figure 3), broader optical effectiveness across an entire lens may be accomplished.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"658\" height=\"599\" src=\"https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2023\/01\/evolution-of-lens-design.png\" alt=\"the evolution of single vision lens designs\" class=\"wp-image-7615\" srcset=\"https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2023\/01\/evolution-of-lens-design.png 658w, https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2023\/01\/evolution-of-lens-design-600x546.png 600w, https:\/\/blogs.zeiss.com\/vision\/us\/wp-content\/uploads\/2023\/01\/evolution-of-lens-design-640x583.png 640w\" sizes=\"auto, (max-width: 639px) 98vw, (max-width: 1199px) 64vw, 658px\" \/><figcaption class=\"wp-element-caption\"><sup>Figure 3.
