Prescription eyeglasses are used by those with eyesight problems and thus require eyeglasses to attain normal vision. Some of the common problems with eyesight that can be solved through the use of prescription eyeglasses include myopia or nearsightedness, hyperopia or farsightedness and astigmatism. As a result of these eyesight conditions, light entering the eye is not able to be focused correctly onto the retina of the eye, thus causing blurred vision.
Prescription glasses usually are made of a pair of corrective lenses, put into place with an eyeglass frames. The typical eyeglass is supported on the nose through the use of pads placed on the nose and temples on the ears. Through these corrective lenses, light entering the eye will be focused onto a focal point on the retina thus allowing the wearer to gain sharper and focused vision.
With myopia being an increasingly common eye condition over the world, the demand for prescription glasses is ever rising. In India, this myopic condition is experienced by one in every three people. In our modern world, prescription eyewear is really no longer a rarity but rather a necessity in many people’s lives.
This change in demand for prescription eyewear has given rise to a myriad of eyewear designs made specifically to suit different tastes. In fact, prescription eyeglasses may also be worn as a fashion statement or to symbolize the personality of the wearer. Designs of prescription eyewear have been influenced by the improvements in materials used to make the corrective lenses. In the past, lenses were originally made only of glass but nowadays break-resistant and lighter plastic lenses are also fairly common.
These marked improvements have allowed eyewear rims to be made of thinner metal or even titanium in some cases. This has opened a whole new door to the designs of prescription eye glasses, which are no longer restricted by the weight of the lenses. In fact, some eyeglasses come with no rims at all!
