More and more people spend their leisure time doing sport on all levels, either recreational or professional. The number of people on professional level is growing. Physical and mental load on all levels of sport is raising as well. When trying to conquer the records and the opponents, training methods are getting better and more intensive. They also require good physical fitness of the whole body. Not everyone is gifted with skills that are helpful when working on individual disciplines, and many people due to their physical abilities cannot devote themselves to some types of sports. The most common issue, which limits people in activities, is an eye error of refraction. In a small number of cases these errors and other changes affecting mostly retina are so serious that they cause an inability to play sports. In general, sportsmen are limited by their eye error of refraction, e.g. by their eyeglasses, which are mainly a mechanical obstacle. Eyeglasses even a sports eyeglasses can disable physical activity in some disciplines, eventhough its owner has good physical predisposition for sport. Mainly in team sport and contact sports it is almost impossible to wear eyeglasses. The frame itself and the size of the eyeglass lenses narrow the field of vision; the quality of the vision is lower on the periphery than in the center of the lens because of its basic physical characteristics. Eyeglasses as a construction can cause serious eye and face damages. The most suitable solution for all sportsmen, whether recreational or professional, who suffer from some error of refraction are prescription contact lenses. Prescription contact lenses are used as a common correction aid for many decades. Their significant spread around the world began in the 1960´s. The soft prescription contacts were discovered by a Czech scientist professor Wichterle. Since then the progress in materials has carried forward even though many manufacturers use materials, which are very similar or even derived from the original HEMA material, the qualitative difference is significant. For sportsmen, contact lenses offer a possibility to do any sports discipline even despite a significant error of refraction. They have many advantages, above all, they don't obstruct mechanically and they don't impede any movements, contacts, actions etc. Constructionwise they are not dangerous for their wearer or anyone around. Because eye contacts become a part of the optical system of the eye, there is no distortion on the periphery of the lens. They don't fog when sweating, they can be used unlimited even when doing water sports such as swimming, water polo, diving and other. |
