История изобретения приборов, улучшающих зрение, теряется в глубокой древности. До изобретения очков, предположительно в последней четверти 13 века, использовались отдельные полированные кристаллы или куски стекла для одного глаза.
Поистине революционным стало изобретение контактных линз, идею создания которых выдвинул Леонардо да Винчи еще в 1508 году. В архиве ученого сохранился рисунок прообраза современных контактных линз: шар, заполненный водой, через который человек с плохим зрением мог лучше видеть. Но только почти 150 лет спустя французский математик и философ Рене Декарт предложил использовать в качестве линзы трубочку с водой, на конце которой было закреплено увеличительное стекло.
Сегодня, когда около четверти населения земного шара имеют проблемы со зрением, рано или поздно перед каждым из них становится вопрос о том, что лучше носить: очки или контактные линзы?!
Сразу же оговоримся, что рекомендовать пациенту очки или линзы может и должен исключительно квалифицированный офтальмолог. Несомненно, что у каждого из этих аксессуаров для коррекции зрения имеются свои преимущества и недостатки.
Очки чрезвычайно удобны тем, кому необходима временная, можно сказать, эпизодическая коррекция зрения. Если человеку необходимо надевать очки исключительно для чтения, работы за компьютером, просмотра телевизора, или вождения, переходить на линзы нет смысла.
Людям пожилого возраста не приходиться: надеть очки все же проще, чем линзы. Так же, медицинские противопоказания имеются у некоторых молодых людей. Контактные линзы, в свою очередь, предпочтительнее при высокой степени близорукости или дальнозоркости, поскольку их использование позволяет обеспечить большую степень остроты зрения. Контактные линзы Biomedics toric недорого можно приобрести в Интернет-магазине, получив при этом гарантии качества и безопасности!
Линзы так же удобнее, если имеется проблема лишь с одним глазом. А в случае если разница между зрением правого и левого глаза от 2,5 диоптрий и выше, линзы помогут скорректировать зрение, избежав ношение различных по толщине стекол на правом и левом глазу.
И в заключение добавим, что иногда бывает полезно сочетание обоих приборов: в летнюю пору линзы необходимо носить с хорошими солнцезащитными очками.
