The daily activity of looking at a digital screen and dealing with up close tasks has become increasingly popular in the modern-day world, meaning the eyes are frequently converging. A physiological trait that varies from person to person, convergence is particularly significant with progressive lenses. The amount of convergence required and achieved, influences near visual performance during close work tasks. Today’s lens designs are "universally optimized" for near viewing, with an average inset value, which is fine in most cases. However, when it comes to any irregularities, near vision may be unfocused or narrow. The personalization that Shamir’s Close Up™ provides is an optimal solution for everyone.

Shamir’s Close-Up technology adjusts the reading zone inset of every lens to the individual patient’s convergence during near viewing. Adjustments are made in 0.1 mm steps within a range of 0 - 5 mm. In other words, the lens is custom-adjusted to the individuals near PD, relative to their far PD. This advanced lens design technology creates lenses that meet individual differences, from physiological traits such as distance between pupils, length of arms, or convergence/divergence disorders, to life style, type of work, hobbies, and so on. The result is a highly personalized lens that meets today’s visual performance demands, whether average or irregular, for near and intermediate viewing.
