Vision – the most important sense
We perceive up to 80% of all information from the outside world visually. Therefore, professional care, in any type of disease, is essential. The most common eye diseases include nearsightedness, farsightedness, astigmatism, amblyopia, presbyopia, cataracts, keratoconus, glaucoma and dry eye.
Myopia is a condition where the eye is longer than it should be and therefore the rays from the observed object are concentrated in front of the focal point, which creates a blurred image. Short-sighted people do not see into the distance very well and when looking, they try to focus, for example, by squinting.
Hypermetropia is a condition where the eye is shorter than it should be and therefore the rays from the observed object are concentrated behind the focal point, which creates a blurred image. Far sighted people do not see near objects very well and therefore they step away from the observed object.
Cataract is a disease linked to age. It affects the human lens, where the by-products of the metabolism build up. This causes changes in its transparency from clear to cloudy, brown and sometimes even white. Visual acuity is gradually worsened and may even reach the point of total blindness in the affected eye.
