Online shopping has extended to contact lenses at very affordable prices. Members of the population who have vision problems will be pleased to know that they can find good quality discount contact lenses online. These products may be of good quality as well.
It is known that very long before the first contact lens were made, Leonardo da Vinci had visualized this pair of small, see through round discs and sketched them. Present day contact lenses were invented by a Czech chemist named Otto Wuchterle assisted by Drohoslav Lim. Lim is credited with developing of the gel used.
It is estimated that there are around 125 million users of contacts in the world. There are many reasons as to why people prefer them. The most obvious reason is that they are not visible and as such do not change the appearance of the wearer. They do not limit the field of vision, a problem caused by wearing glasses. Further, they are not affected by rain or steam. These lenses also have the ability to correct some problems that a pair of glasses can not.
Glass was the very first material that was used to make these, which did cause problems for people because wearing them for a long period of time caused irritation. The next development was the hard lens which were made from Perspex or Plexiglas also known as PMMA. William Feinbloom created it. This material though isn?t great either, because oxygen is not able to reach the cornea of the eye and this could potentially develop certain eye conditions after some time.
In the 1960?s, contacts became much better because Wuchterle and Lim started using hydrogel. Throughout the years, this has been advanced so that they are now more secure and comfortable. Original lenses were clear, but now they can have a tint so people can see them better and they can also have other colors added to change the appearance of the actual eye. Someone who has green eyes can change them to blue. Some have even advanced to the point that the eye is protected from UV rays.
You need to visit an optometrist if you wish to change your glasses for a new set of lenses. The prescription for glasses is the same as the one for contacts. The optometrist will examine your eyes to ascertain whether contacts will be suitable.
Ordering them on the Internet, through mail, or by telephone can be cheaper. Optometrist offices may charge more for their products. Although you need to take into consideration the shipping and the insurance costs.
When looking online, there are so many options to choose from including brands, designs, or colors. Just remember that the online products do not mean lower quality. They can be discounted from buying in large quantities at cheaper rates.
