What is accommodation?

Accommodation refers to the eye’s ability to adjust the curvature of the lens depending on the distance of the object being viewed. When looking at nearby objects, the lens becomes more curved. When looking at distant objects, the lens becomes flatter.

The loss of the eye’s ability to accommodate is a natural part of the ageing process. However, even from birth, the lens of the eye slowly loses its elasticity and, consequently, its ability to focus sharply at different distances. The closest point at which an object can still be seen clearly moves further and further away from the eye. In people with normal vision, however, the decline in the eye’s ability to accommodate usually only becomes noticeable between the ages of 40 and 50. One way to correct presbyopia is to wear reading glasses, although constantly putting on and taking off glasses in everyday life can be very inconvenient. The ideal solution is varifocal lenses. They provide sharp vision from near to far.
