Eyes & Vision
The eye is one of our most important sensory organs, playing a key role in our ability to find our way around and perceive our surroundings in our daily lives. When vision deteriorates, it can affect many areas – for example, reading, watching television or interacting with other people. In our knowledge section, learn how our vision changes, what can cause impaired vision, and what solutions can help in everyday life.
Visual acuity & magnification requirements
Visual acuity determines how well we can recognise details in everyday life. Find out how visual acuity and magnification requirements are linked, what affects our visual acuity, and what you can do if it starts to deteriorate.
As eyes age
With increasing age, close-up vision often becomes increasingly difficult. The first signs of this usually appear from the age of 40. Read here about how presbyopia develops and how modern vision aids can help maintain your usual quality of life when glasses alone are no longer sufficient.
Eye diseases
As well as short-sightedness and long-sightedness, our visual performance can also be impaired by various eye diseases. These usually cause irreversible damage to the eye. Find out more about the most common eye diseases and how to recognise them.
