The A to Z of Contact Lenses – A to F
Astigmatism – one of the most common eye problems, astigmatism is, in its most basic form, being unable to focus fully on any object. There are many different reasons for the cause of astigmatism, but whichever reason that is, contact lenses are generally recommended as a solution over glasses.
Bifocal Contact Lenses – prescribed for people with presbyopia (the inability to switch quickly and properly focus on close and far proximity objects), bifocal contact lenses ensure that the wearers vision is no longer distorted, regardless of where or what they are looking at.
Colour Blindness – being colour blind is somewhat of a common occurrence in men, rather than women. Making your eyes unable to distinguish between certain colours due to the cone cells working incorrectly, medical contact lenses are now available to aid this problem, by filtering certain light colours that enter the eye into their recognisable colour.
Daily Contact Lenses – the majority of contact lenses were originally designed and developed to be worn only for a short period of time. Over the years, contact lenses were researched and manufactured to a higher standard and are now available to wear on a daily basis – a lot of which can now be disposed of after a single day, with a replacement pair ready to be worn the following day.
Extended Wear Contact Lenses – following on from the Daily Contact Lens research, Extended Wear Contact Lenses were designed and are now available to be worn for more than a single day – even through sleep.
Fick – At the end of the 19th Century, in 1887, a German physiologist created the world’s first contact lenses. Made from blown glass, these contact lenses were uncomfortable to wear and difficult to fit and remove – however, importantly, they did help to correct the wearer’s vision.
