In order to focus light from close objects onto the retina the crystalline lens changes its shape, a process called accommodation. The older we get the more rigid the lens becomes making focusing at near progressively more difficult. This reduction in accommodation is known as Presbyopia and is a normal part of ageing.
We usually start to notice Presbyopia when reading in low light conditions becomes more difficult. When moving from distance to reading tasks it can take the eyes longer to refocus. Spectacles can be prescribed to supplement the reduced focusing power of the eye. These can vary in power depending on the reading distance required. For example, a different strength lens would be needed for computer work than for reading a book.
Our Optometrists will talk to you about your lifestyle and hobbies which will be taken into account when your reading addition is prescribed.
