The Contact Lens Family

It may be surprising to believe, but Leonardo da Vinci was the first person to come up with the concept of the contact lens. Of course, it was not in the same manner that we use it today, and so the entire credit of inventing the contact lens actually goes to a another person altogether. The most common way of correcting vision defects has been the eye glass. However, its popularity over the years has decreased considerably and given way to its more modern and fashionable counterpart – the contact lens.

Before you decide on buying a pair of contact lenses, it is important to know the basic types of contact lenses available in the market today.

  1. Daily wear contacts – As the name says, these contacts are for daily wear. You put these in your eyes when you start your day and discard them at the end of the day. Many people prefer this option because of its convenience; no cleaning solutions or worry of infections of the eye. Each new day starts with a fresh new pair of contact lenses.
  2. Extended wear contacts – Opposite of the daily wear, the extended wear contact lenses can remain in your eyes and can also be slept in. Typically, you can wear them 24/7 for up to two weeks. After the two weeks are up, you discard then and start with a new pair. Although it is very convenient, chances of infections are very probable.
  3. Regular/Disposable – This eye wear is simple and easy to use. You wear then everyday, remove them before sleeping and soak them overnight. Next day, you clean them again and pop them back into your eyes. While some people still use these for a year before getting a new pair, some opt to use the disposable ones. The disposable ones still have to be taken out and cleaned overnight, but you usually wear them for 4-6 weeks and then start with a new pair at that time.
