Leonardo Da Vinci was the first person to describe and sketch the idea of contact lenses in 1508. But it took more than 300 hundred years to be fabricated and worn in the eye. William Feinbloom produced the first contact lenses in the year 1936 containing both glass and plastic

Today we have variety of lenses available in the market, which vary according to the needs of the people. They include disposable, extended wear, flexible wear, and gas permeable and even contacts for special needs. Thin finely crafted plastic discs designed to fit the cornea of the eye are more helpful than the eyeglasses as the contact lenses provide better peripheral vision.

For the people who choose to wear contact lens for the first time, here are some types of lenses and guidelines to follow.

Types of Lenses:

Soft lenses:

Disposable lenses:
Disposable lens are for the people who don't have time to do daily care and cleaning to their contacts. You can choose either a daily disposable one or that which will last for a week or two. Daily disposable ones do not require disinfecting and cleaning solutions. These are available for different eye types, and also in colour if you opt to use a colour less for a while. Consult the optometrist for the right brand.

Annual soft contact lenses:

They last for a year. Made of soft material, which aid oxygen transmission, this helps in preventing drying of the eyes. Once these are removed after wear they need careful cleaning, disinfecting and storage.

Soft lenses can be worn for 14 hours at a stretch.

Gas Permeable/ Rigid gas permeable/ Oxygen permeable lens

Gas permeable's provide excellent clarity of vision, durability and transmit more oxygen to the eye than the soft lenses (except newer silicon hydrogel soft lenses). They are easier to clean and last up to a year. But GPs have their own flaw. People take some time to adapt wearing these lenses as they are made of stiff material. They are made of semi- rigid material that don't contain water. SynergyEyes lens have overcome this deficiency by combining a GP center with soft outer ring, thus providing a comfort and visual acuity.

Flexible and Extended wear contacts:

These are specially designed fro people who choose to wear the lens continuously and hate to put them in and take them out several times a day. You can even sleep with these lenses. They are made of material that allow more oxygen to reach your eye's cornea. You can use them without removal for successive seven days or 30 days in case of two brands.

Torics for astigmatism:

They provide the same level of comfort and clarity vision. What makes them different is they help in correcting astigmatism. Astigmatism according to encyclopedia is the inability of the cornea to properly focus an image onto retina, thus resulting a blurred image. Torics are available in both GP and soft lenses. They are designed to stay in the same position even as being worn.

Cosmetic Lens:

There are four types of coloured contact lenses: visibility tints, enhancement tints, opaque colour tints and light-filtering tints. The exact power value is in the center of the colured lens. Cosmetic or coloured lens follow the same cleaning regime. Many of these lenses are available without visual correction. Cylindrical lenses are not available in colour format.

About 38 million people wear contact lenses only in USA. It has won many customers who are affected by visual problems. Contacts can be fun, safe, and useful than your eyeglasses, but it needs its own care and has many rules to follow.

Doctors warn users not to share their contacts with others, as it is more prone to bacterial eye infection. Wash your hands and dry them with lint-free towel. Try to avoid moisturising soap, as they are not good for contact lenses. Do not rinse your contacts under a tap as they contain microorganism that cause eye infection and that can actually make them uncomfortable to wear. Remember not to switch solutions or use a product that was not recommended by your eye specialist.
