Many people have often said that eyes are the windows to the soul. So if that is considered to be true, then it may be the desire of many people to have soul windows that are both properly functioning and pleasing to look at. Vision is not very commonly a human function that remains without flaws and imperfections throughout the life of a person. Researchers have discovered a great deal of info on the eyes through studies such as the ones that have shown that eyes can process over 36,000 pieces of information every hour. So, if a person has poor vision, they may be missing out on information that they could be processing. For those that are in need of improving their vision and want to do so in a manner that may be considered unique and fashionable, there are vision treatment centers and eyewear stores in Canada such as the Calgary, Alberta optical centers.
Vision impairing conditions such as myopia, hyperopia, astigmatism, and presbyopia are some of the common causes for corrective lenses to be needed. Eyewear in the form of glasses has existed for hundreds of years with historical types including the prince nez, the monocle, the lorgnette, and scissor glasses. Today, eyeglass lenses are most commonly made out of plastic materials such as CR 39 and polycarbonate. Plastic material lenses are considered to be more effective because they reduce the risk of breakage and they also weigh less than glass lenses. Similar to glass, plastic lenses can usually be coated with scratch resistant coatings. At the Calgary, Alberta optical centers, a wide variety of corrective eyewear may be found.

Some of the frames found at the Calgary optical centers are designer frames which come from Europe through manufacturers in Italy, France, Germany, Denmark, and Spain.
