Many people with less than perfect vision will be happy to know that discounted contact lenses are available over the counter and that ordering is quick and easy.
These two small transparent round discs have an interesting history. It is said that Leonardo da Vinci described and sketched them 300 years before the first pair was sold. The inventor of the soft contact lenses popular today was Otto Wuchterle, a Czech chemist and Drohoslav Lim, his assistant who also developed the gel used in their manufacture.
An estimated 125 million people use contact lenses worldwide. People wear them for different reasons. First, they are invisible and do not alter your appearance or limit your field of vision the way glasses do. In rainy weather they remain clear because drops do not collect on them and steam does not affect them either. There are also some eye conditions that cannot be effectively corrected by wearing glasses.
The first material used in its manufacture was glass. This had the disadvantage of irritating the eyes making it impossible to wear them for long periods of time. Then an American optometrist William Feinbloom made the so-called hard lenses of PMMA, better known as Perspex or Plexiglas. It was a step in the right direction, but still not ideal because this material prevents oxygen from reaching the cornea of the eye. Without oxygen, eye diseases can develop.
When Wuchterle and Lim started using hydrogel in the 1960s, a new era began. Since then, the material has been refined to make the final product comfortable and safe. Today, some soft lenses have a faint blue tint to make them easier to see. Color can also be added to change the appearance of the eye for cosmetic reasons. They can also be treated to limit the risk of UV damage to the eye.
To buy a pair, you’ll need to have an eye exam and get a lens prescription. The one for those glasses you might want to replace won’t suffice. To get them for the best price, shop around. You can order them online, by phone or by email. The discounted contact lenses shouldn’t cost you nearly as much as those from your local optometrist. Take into account the costs for shipping and insurance.
When ordering online you can choose from different brands, colors and designs. The fact that you buy a product at a discount does not mean that the quality is less. Suppliers who can offer discounted prices are usually those who buy in bulk from manufacturers and can afford to lower the price. Usually their products are of the same quality as the more expensive branded ones.
To get the best deal, shop around and check supplier credentials. The online world can be dangerous. If a supplier won’t allow you to ask questions before you buy, or if their contact information looks suspicious, stay away. Search the internet for independent opinions.
The benefits of discounted contact lenses are plain to see. Now it’s more affordable than ever to look good and still look as good as ever. There are many places to find them on the net. Make sure you choose well.
