Accommodation is the ability of the eye to focus on objects at different distances. This is achieved by adjusting the refractive power of the eye. If this no longer occurs smoothly, presbyopia is present.
This can usually be easily corrected with glasses or contact lenses.
Research into the mechanism that allows us to see clearly at different distances has not yet been completed. We therefore do not yet know exactly how it works.
What can be said with certainty, however, is that the lens changes its curvature and its refractive power. The change in the lens is made possible by the so-called ciliary muscle. This is relaxed when you look into the distance and is tense when you look closer. The lens of the eye is attached to the ciliary muscle by so-called zonular fibers. The lens is elastic so that it can be deformed with muscle power, but it cannot be controlled arbitrarily.
The altered ability to accommodate in old age
With age, various changes occur in the body.
Naturally, the eye is also affected. Our lens loses elasticity with increasing age, and the elasticity of our ciliary muscle also decreases.
This often becomes noticeable from the age of 45.
This makes it difficult for us to adjust the distance from far to near. We find it difficult to focus and focus on objects at close range.
The ability to accommodate therefore decreases.
Those affected most often notice this when reading. This is why reading glasses are often needed as an interim solution. If you notice that you also need reading glasses, don't hesitate to take a look at our website.
If you already have short-sightedness, you can correct both vision defects perfectly with customized varifocals and restore sharp vision at all distances.
Our varifocal specialists are also on hand to help you with this. Make an appointment with us to receive the ideal advice for your needs.
Whether you need simple reading glasses, single-vision glasses or varifocals, you will find the right solution with us.
