The Evolution of Modern Glasses

A few decades ago, the most common eyewear in the United States was a pair of plastic, shiny and eye-glazed spectacles that originated from the manufacture of De Beers. These were the standard eye wear for both men and women in virtually every major American city. However, this was just the beginning. In the following decade, high-tech temple contact lenses took America by storm as more people discovered the benefits of these lenses for vision correction and improved eye health.

It is amazing to think how far eyeglass lenses have come since their introduction into everyday use. Today, there are prescription eyeglass lenses on the market that reduce or eliminate nearly all of the light that goes through your eye. This is achieved by using special lenses with low-refractive power (LPR) and high-index (IHR) coating. Together, these elements reduce the amount of reflected light while enhancing the sharpness and color of visual images. This technology allows for much better vision quality, especially with respect to glare, and helps to ensure that everyone who wants to see properly can.

Another advance in modern glasses has come in the form of polarized lenses. These lenses have a high-power F-number and lower dispersion to reduce or eliminate haziness from reflections and light scatter commonly associated with bifocals. Polarized lenses have also been found to greatly reduce glare and increase object brightness while eliminating most of the light scatter from high-definition video footage. Some manufacturers have even added anti-reflective and anti-scratch elements to some of the most expensive polarizing lenses available.

Over the past few years, colored contact lenses have become very popular. Typically, a person chooses a color from a pair of glasses, either all white or all black, and applies them over the iris of the eye. The colors are matched perfectly and create a very unique look that some find to be quite attractive. In addition to being attractive, however, colored contact lenses require eye wires to be attached to the eye during the fitting process, as well as a prescription for each specific color. Wearing a pair of non-prescription colored contacts is generally not advised due to the health risks associated with them.

Information

A modern lens incorporates both the above features and provides far better comfort than its predecessors. Glasses that include a progressive lens are designed to change progressively through the course of the day. At day one, they are almost completely clear and prescription lenses are not required. Throughout the course of the day, as the prescription changes, the glass begins to blur and become less clear until finally, at night, the prescription changes once again. A progressive lens will help to compensate for these changes as well as provide a bit of comfort to the wearer.

Finally, another advancement in glasses has come in the form of multifocal lenses. As the name implies, these pairs of glasses feature two different prescriptions within the same frame. For example, if you need to wear reading glasses at work while also using contacts for the home, the pair would have two prescriptions in them instead of one. This is helpful for those who are not comfortable wearing two different frames for the purpose of seeing either of their two primary necessities.
