Contact lenses are becoming increasingly popular and nowadays most people choose them instead of glasses. The degree of vision obtained from contact lenses is superior to that of glasses because they allow you a wider field of vision.

Even babies and small children can wear them to correct a squint or after an operation. If the reason for wearing lenses is cosmetic, children over 10 can wear them. Old people are also opting for contact lenses nowadays.

Eighty per cent of all contact lenses worn today are soft. Hard perspex lenses which are less comfortable to fit and wear are rarely prescribed nowadays.

Colored lenses are exactly the same as other types except that they are tinted. It is only a myth that they are bad for you. Daily disposable lens systems have some advantage over other types as there is no need for a complicated cleansing routing, no storage case to be contaminated and no cleaning solutions to irritate the eye. However, disposable lenses made to last longer than a day need to be properly cleansed. Careful hygene is vital to keep your lenses clean, comfortable and safe from harmful bacteria.

People who are prone to allergies can be more sensitive to lenses. Also during pregnancy, they can be more uncomfortable. It's best to take contact lenses out while flying as the pressurised air in the cabin dries out the eye and reduces the flow of oxygen to the cornea. Sleeping in contact lenses is unadvisable unless they are made especially for that. Make up can be worn while wearing contact lenses but it is much better if you insert them before you start applying any make up. Follow-up appointments with the optician are vital for contact lens wearers. It is also advisable to carry a pair of glasses in case a lens is lost or becomes uncomfortable.
