Close-up and personal

Close working distance activities undertaken by modern patients has led to an increase in the frequency of eye convergence, said Shamir.

The amount of convergence required and achieved influences near visual performance during close work tasks, but the company said many of today’s lens designs were universally optimised for near viewing, with an average inset value, which is fine in most cases. However, when considering any irregularities, near vision may be unfocused or narrow.

Shamir’s new Close-Up technology adjusts the reading zone inset of every lens to the patient’s convergence during near viewing. Adjustments are made in 0.1mm increments within a range of zero to 5mm.
