Eye contacts, also known as contact lenses, are normally used for correcting eyesight problems. They’re placed over the cornea of the eye, and come in a multitude of strengths and types to help correct all variations of vision impairment. They’re often used as a substitute for glasses, as many people prefer the appearance and practicality of eye contacts. They don’t steam up, are less affected by bad weather, and can be far more suitable for playing sports. They can offer a wider field of vision than glasses can, and can even fix problems that can’t be solved by glasses alone. They’re especially useful for those who need a stronger prescription and would need to have thicker glasses as an alternative. Eye contacts are used by an estimated 125 million people worldwide, with the majority favouring “soft” contacts for their comfort. These were invented in the 1960’s by two Czech chemists, Otto Wichterle and Drahoslav Lim, who developed the “hydrogel” that soft contacts are made from. They quickly overtook the popularity of “rigid” eye contacts. Rigid contacts are, as you would expect, made of a stronger material that are thicker than soft contacts. They’re still available, but are used less prevalently as they require far more adaptation and perseverance before they can be worn comfortably. In comparison, soft eye contacts offer immediate comfort to users. A lot of people worry about using eye contacts for a number of reasons. They may not like having to put their fingers on or near their eye, or they may worry about “losing” the contact when it’s inserted. But they need not worry. Inserting a contact lens is painless, and, after practice, is extremely quick and easy. And there’s no way that a contact can be lost in the eye – there’s a thin, transparent membrane around the eye that stops an eye contact from moving too far. You need to have a routine of care put in place when using eye contacts. Always take note of how long you’ve been advised to wear the contacts for – rarely can you keep them in all day, and soft contacts should never be worn throughout the night. Doing so can cause infection or could even damage the cornea, so it’s vital to take them out before going to sleep. You’ll need to keep a stock of any cleaning or rinsing solutions required, and always remember to follow instructions regarding the cleaning of eye contacts exactly. Failing to follow proper care procedures can result in damage to the contacts, which could in turn damage your eye. Be especially careful not to get any dirt or dust in them. If you don’t feel that you can keep up with the routine of care for your contacts, maybe consider glasses instead. But, the convenience and practicalities of using eye contacts far outweigh the downside of having to spend time caring for them!
