How can eye defects be corrected
How can presbyopia be corrected?
Contact lenses can also be useful, especially when presbyopia is added to another existing visual impairment. They lie on the, while they slide on a film of tear fluid. Contact lenses correct the lack of refractive power of your own eye lenses in a similar way to eyeglass lenses. The advantage of contact lenses is that they do not change the appearance and do not interfere with leisure activities such as sports. Their disadvantage is that they need care that can be irritating and there is little risk of infection. They have to be put in every morning and taken out again in the evening - if you can tolerate wearing the lenses all day. Some people only use contact lenses for a few hours and then turn to glasses.
A distinction is made between hard and soft contact lenses. To prevent contamination and dehydration, contact lenses are stored in disinfecting care solutions overnight. The costs for lenses and care products can differ depending on the provider. Soft lenses are also available as disposable lenses that are thrown away after each use. Care products are then not necessary.
In order to fit contact lenses, a consultation in an ophthalmologist's practice or an optician's shop is necessary. For presbyopia, dual or multifocal contact lenses are also possible. Similar to the corresponding glasses, there are different zones for close-up and television. Sometimes contact lenses are offered as a monovision system. One corrects the so-called guide eye for the distance, another the second eye for the near. In many people, the brain adapts to this change over time. However, if the visual impression remains unpleasant, the attempt with the monovision lenses is terminated. Because spatial vision deteriorates with monovision, glasses must also be worn when driving, for example. It also helps the “reading eye” achieve good viewing quality in the distance.
