Selecting contact lenses should be done only after consultation with your optician as then you can choose the right kind depending on your eye condition. Depending on the condition of your eyes, the doctor will advice whether you are a candidate for soft or hard contact lens.
While most people prefer soft contact lenses, a small number wear hard ones due to a medical condition called astigmatism. If you are planning to wear contact lenses on a consistent basis, then hard lenses are advisable, however, if you want to wear them occasionally and use regular glasses too, then soft contact lens are best.
Types of contact lenses – Soft contact lenses are available in varied categories depending on usage and cost. Sometimes people wear contact lenses to change their eye color. These cosmetic lens do not affect vision and can be worn as and when the user requires them.
Contact lenses for daily wear – Though soft contact lenses are not very durable, people prefer them as they are least expensive and can be easily replaced if broken. Contacts worn on a daily basis have to be disinfected every night in a prescribed solution given by manufacturer to keep them free of dirt and germs. Depending on type and brand, these contact lenses have to be replaced as per the prescribed schedule. Doctors advice against wearing contact lenses at night as they make eyes vulnerable to corneal infection due to lack of oxygen.
Toric contact lenses – When a person is suffering from blurred vision due to defect in their cornea, a condition called astigmatism, then a special lens is fixed inside their eye called toric contact lens. This will help to give a sharper vision and is more expensive than regular contact lenses.
Multifocal lenses – Sometimes people tend to lose focus with age. This condition is called presbyopia and it can be corrected with both bifocal and multifocal glasses. Under these situations, doctors advice on monovision contact lenses which are a combination of lenses for near vision and distance vision.
Contact lenses are a welcome replacement for people who have work glasses for years and would now like to opt for something better. Whether you are buying contact lenses for vision problems or cosmetic purposes, always take the advice of an experienced optician to avoid problems of eye infection.
