Contact lens is a thin transparent curved lens that is placed on the surface of the eye to correct one’s vision. Before the technological advances that made the contact lenses of today possible, thinkers like Leonardo da Vinci and René Descartes experimented with water’s refractive power over 500 years ago. But the main advancement in the technology behind contact lenses happened during the 20th century.
In the 1880s glass production technologies made thin lenses possible for the first time. In 1888, Dr. Adolf Fick produced the first successful contact lens. But these lenses were thick, heavy and they covered the entire eye. In the 1920s and 30s, advances in materials made it possible to produce lightweight lenses to the shape of the eye for the first time. In 1948, an optical technician named Kevin Touhy introduced the corneal lens, the smaller contact lens we see most often today. In 1959, Czechoslovakia scientists Otto Wichertle and Drahoslav Lim produced lenses with a new plastic known as hydrogel. These were soft and flexible and could be easily shaped and moulded. As time passed, contacts became thinner and thinner, reaching a thickness of merely 0.1mm. In the 1970s, Bausch and Lomb were the first to commercially release hydrogel lenses, which they named SofLense. Soft lenses remain popular to this day.
While contact lenses are mostly used for vision correction, there are also lenses for purely cosmetic and novelty purposes. Corrective lenses are designed to correct refractive error. This is achieved by directly focusing light so it enters the eye with the proper power for clear vision. Spherical lenses bend light evenly in every direction. They are used to correct myopia and hypermetropia. Multifocal contact lenses can be compared to spectacles with bifocals or progressive lenses. These are designed for viewing through the centre of the lens, but some designs enable viewing through the reading power - similar to bifocal glasses. Cosmetic lenses enable changing the appearance of the eye. These lenses may also correct refractive error. Contact lenses are generally quite safe as long as they are used correctly. Improper use may affect the eyelid, the conjunctiva, and even the whole structure of the cornea. Poor lens care can lead to infections by various microorganisms including bacteria, fungi and Acanthamoeba (Acanthamoeba Keratitis).
Prescription contact lenses today can be manufactured with virtually any lens power. That means that with a prescription as low as 0-25/+0.25, you can wear prescription contact lenses. Nevertheless, prescription contact lenses are a medical device and you will need to have an exam to determine your prescription and whether they are suitable for your eyes before you order contact lenses online.
If you are susceptible to dry eye syndrome or have sensitive eyes, your eyes may not be suitable for contact lenses. It is also advised to have regular contact lens exams to ensure that your lenses are always fitted with the right prescription power and you are achieving the best vision possible, however low it may be. Once you have your prescription, you can order contact lenses online with Vision Direct.
