Great Giveaways or Shameful Promotions- The Truth About Free Contact Lens Samples!
Extra, Extra, Get your free samples of contact lenses here...So you are looking for free samples of contact lenses? Perhaps you saw a commercial that said "visit our website for a coupon to receive free samples of contact lenses." Or, "see your eye care provider today for your free pair of so and so lenses."While this a great way for lens manufacturers to have you try their brand of contact lenses, most contact lens fitters do not require such coupons.In order to get free samples of contact lenses, that particular lens must still be fit to your eye. Therefore you must still visit your eye care specialist. A properly fit soft contact lens must center correctly, move slightly with a blink, match the contour of your eye, and correct your vision. Any lens that does not meet all those minimum criteria does not fit. So why bother with some free samples of contact lenses that won't work for you?Here is a secret the other websites and commercial advertisements might not be telling you: You don't need a coupon to get free samples of contact lenses.
If you are having issues with your current lenses, or have never worn lenses before, your specialist will fit you with something different. Depending on the type of fit, your lens fitter may have diagnostic lenses in the office for evaluation. If the diagnostic contact lenses are a good fit, chances are you can take them home to try out (yes, even without a coupon).There are some instances where free samples of contact lenses can not be handed out. For example, if you do not wear a pre-packaged, disposable contact lens. Non disposable lenses are not given to eye care providers as diagnostic tools and therefore will need to be ordered per case.
Also, gas permeable contacts can not be given out as free samples. Every gas permeable contact lens is made per specs for an individual patient; therefore it would not be possible to have free samples on hand.So you can search out coupons for free samples of contact lenses, or you can let your specialist decide which lenses might be a better option for you..

Contact lenses come in a variety of colors and effects these days. These include basic white contact lenses. Courtesy of the fact that many of these lenses are now created for cosmetic purposes, with a power of 0.00, basic white contact lenses can be made available for all, not just those with poor eyesight.
One must wonder of course, how basic white contact lenses could affect poor vision, and the answer is that they couldn't of course.
However, at a party, the effect of pure white in one's eyes could be very striking, if not a little bit scary .....
In a dramatic sense, theatrical contact lenses are used to help portray specific characters, or idiosyncrasies that these characters may possess. If a character were blind, then having basic white contact lenses could have a significant effect on the portrayal of that character. Having said that, basic white contact lenses will have a 'pupil hole' which would show up as a black dot in the eye....

Colour Contact Lenses - Corrective, Therapeutic and Cosmetic
Contact lenses are classified as corrective, therapeutic, and cosmetic. For those who are short sighted, near sighted, or who have astigmatism (all refractive defects of the eye) corrective contact lenses are in order. In these cases, an eye patient will mostly likely be prescribed "spherical" lenses. Therapeutic contact lenses cure other problems that are non-refractive, like "dry eye," and some types of therapeutic lenses even deliver medicine to the eye.
Two types of cosmetic lenses are colour contact lenses and special effects contact lenses. While these lenses occasionally correct vision when needed (they are basically spherical lenses), they also can blur vision because of their design.
Colour contact lenses essentially change the appearance of the eye. Some people may require colour contact lenses for less superficial reasons (perhaps they have a physical deformity on their iris) while others may simply want to ditch their natural brown eye color for a more...

Have you ever wondered; how do contact lenses work?
Have you ever wondered; how do contact lenses work?If you wear lenses, or even if you don't, chances are you have asked yourself, "how do contact lenses work?" After all, it's just a little piece of plastic. It's amazing that without them, your vision can seem awful. And with a little thin lens, everything is clear. So let's take a closer look; how do contact lenses work?In their simplest form, contact lenses are nothing more than an optical lens; similar to that in a pair of eyeglasses, only much smaller and of a different material. For the nearsighted eye, the lens is a minus power.
On eyeglasses, this makes for a thin center and thick edge. The same goes for contact lenses, a very thin center and a thicker edge. The variation of the thin to thick makes up the power of the lens. For example, a -14.00 lens has thicker edges than a -2.00.The inside curve of the lens, also called the base curve, is designed for optimum fitting on the cornea. Base curves are measured in mm of radius....
