The basic principles behind contact lenses originated with Leonardo da Vinci back in 1508. Although da Vinci’s ideas were more focused on the mechanisms and accommodation of the eye rather than on correcting vision, he is generally credited with establishing the general principles eventually used to create contacts. While it took more than three hundred years before the first contact lens was actually successfully manufactured and worn, these optical devices certainly aren’t a new invention. That said, however, today’s contact lenses are far more advanced and sophisticated than those that existed even in the mid-twentieth century. In fact, in the past twenty years, there have been many significant changes and advancements that have taken place with respect to the design and fabrication of contacts.
Contact lenses are thin lenses, now made of plastic, which float above the cornea on the tear layer of the eye. Corrective contacts are specially shaped to improve vision by compensating for sight-related problems such as nearsightedness, farsightedness and astigmatism. While even in the not-too-distant past contacts were often difficult and uncomfortable to wear, one of the major advancements in the optical field has been a significant increase in the comfort of these optical devices. For the most part, the greater comfort offered by modern contacts has resulted from the use of new, sophisticated materials and technologies in . . . → Read More: A Synopsis of Contact Lenses

With a prescription for contact lenses in hand, it is possible to buy your contact lenses from stores, the Internet, over the phone, or by mail. There are 75 million contact lens wearers worldwide and 31 million live in the U.S. alone. The choice of which of the contact lenses is right for you should be based only on an examination by your doctor or eye care professional, not over the phone.
In the U.S. contact lenses marketplace, 82 percent wear soft lenses, 16 percent wear rigid gas-permeable and only 2 percent wear hard. Contact lens wearers are usually surprised and happy with the level of comfort the lenses provide.
Bifocal correction is possible with either soft or rigid lenses. Soft contact lenses are made of very soft, flexible plastics that allow for oxygen to pass through to the cornea. If you plan to wear lenses for more than 18 hours for the purpose of an eye color change, then buy colored soft lenses.
People who have good distance vision but will need help for reading can get a monovision reading lens for one eye. Soft lenses have the added benefit in that soft lenses are not as likely as rigid lenses to pop out or get foreign material like dust underneath them. Soft lenses also come as disposable products — used once and . . . → Read More: Time-Tested Tips For Shopping For Discount Contact Lenses

The functional advantages of contact lenses over glasses can be felt in areas like sports, working in humid conditions and also in occupations where glasses can be very inconvenient and may not be compatible when using equipment like special headgears. Contact lenses also offer aesthetic advantages as they do not alter the image of the person wearing it.
When contact lenses are worn correctly on the cornea of the eye, the vision is very similar to the natural vision. The objects are seen in the right size and position without any kind of distortion of the image. When glasses are worn, the distance between the glasses and the eye vary making the objects appear smaller or larger than the actual size, position etc.
Contact lenses are not altered by bodily movements, as in the case of sports or similar kind of activities. They remain stable providing stable and clear vision to the wearer. When glasses are worn, the vision is unstable while moving or running, in turn affecting the performance of the wearer.
Contact lenses provide a better and wider peripheral vision than the glasses. Contact lenses move with the movement of the eyes and the wearer always looks through the clearest part of the lens called the optic zone. When glasses are worn, it blocks the . . . → Read More: Advantages of Contact Lenses Over Glasses
