The idea of contact lenses has been around since 1508 when Leonardo da Vinci wrote the Codex of the eye, Manual D, but it was not until Adolf Fick fitted the first successful contact lenses in 1888 that they were actually put to use. Since then, advances in technology and a deeper understanding of the anatomy and functioning of the eyes have brought about more effective and comfortable contact lenses.
Many people who need to wear corrective lenses to remedy visual problems are now opting for contact lenses in favor of eyeglasses. Indeed, there are a number of good reasons to.
Perhaps the most obvious reason is cosmetic. No matter how eyeglass designers remodel, enhance, or smarten up eyeglass frames, there will always be that piece of plastic or wire sitting on your nose and ears, and hanging in front of your face. Of course, they have come up with beautiful designs, but many people believe that the best way to look good is to have nothing obstructing your face.
This is especially true for persons whose eyes require lenses of very high strengths, as these could make their eyes appear much bigger than they really are. This distorts the proportion of their eyes to the rest of their facial features.
Equally important, some would actually say more important, are the visual reasons. Contact lenses deliver a more natural vision. This is because the distance between the eyeglass lenses and the eyes can create some distortion in the size and distance of objects seen. Also because of this distance, peripheral vision is narrowed. As you look to your side, your eyes focus on an area outside of the corrective lenses, which results in blurred vision.
Vision is also more stable with contacts as they are not affected by quick and even bouncy body movements. This is why they are preferred by sportsmen and women. Even if you are not into sports, glasses can periodically slide down your nose while sweating.
When walking from an air-conditioned room out into a warmer area, glasses often fog up. And if it is raining, you can expect a few raindrops splattering over the lenses. These require you to wipe the moisture off. With contact lenses, these are not a problem.
