How Technology Made Prescription Eyeglasses Cheap

Prescription eyeglasses are available in many different styles for many different uses. But despite the word “glasses” in the name, most of the lenses utilized in today’s prescription eyeglasses are in fact made of plastic. And thanks to modern technology, due mainly to advances in lens construction, they are much more affordable than ever before. In fact, redistribution programs exist for prescription eyeglasses that allow for the donation of gently used pairs to the poor and needy, a significant factor in reducing a worldwide public health problem.

Traditionally the most expensive part of a pair of prescription eyeglasses, modern lenses are constructed of plastic and are manufactured overseas. But despite the negative connotations surrounding the word “plastic,” lenses made of the material are lighter weight and much more durable than the glass ones prior to use of plastic lenses.

And believe it or not, plastic lenses are optically a lot more advantageous than glass, allowing light to pass through much better even as they absorb harmful ultraviolet rays in a much greater amount. They’re thinner, too, vastly increasing wearer comfort while much more shatter-resistant. And now even flexible frames are available for casual use at ordinary prices! Moreover, thanks to the internet, cheap eyeglasses can be readily purchased.

However, it is a good idea for an eye exam whenever you wish to get a new pair (unless, of course, you’ve already had your eyes examined quite recently – once a year is considered just fine, with no more than twice a year deemed necessary), and one convenient way to do both is to go to an old-fashioned brick-and-mortar eyeglass store.

Prescription eyeglasses are here to stay despite advances in laser eye correction surgery. While both methodology and technology continues to improve, they might soon reach their limit with guaranteed 20/20 vision for all still unachieved, necessitating the regular purchase of cheap prescription eyeglasses.

How Plastic Changed Prescription Eyeglasses

Prescription eyeglasses are obtainable in a variety of styles for a number of uses. But despite the word “glasses” in the name, most of the lenses utilized in today’s prescription eyeglasses are basically made of plastic material. Regardless of the negative connotations of the term “plastic,” lenses made of such materials are of a lighter weight and a lot more long-lasting than old-fashioned one made from real~actual glass.

The plastic lenses in prescription eyeglasses also bear much more advantageous optical properties than actual glass, believe it or not. These modern materials make it possible for light to pass through significantly better, while being able to absorb dangerous ultraviolet rays in substantially higher amounts.

They are also created much thinner without the need of sacrificing any performance characteristics, thus vastly decreasing weight and offering maximum wearer comfort. Modern prescription eyeglasses with plastic lenses also are used to aid the correction of numerous vision abnormalities, including higher-order ones involving the retina and cornea of a person’s eyes.

Thanks to such plastics, modern-day prescription eyeglasses can admit the application of scratch-resistant coatings so that the lenses are as durable as real glass. Other sorts of coating can also be applied to these lenses to make them easier to clean or to reduce glare or to improve night vision. One kind even makes it possible for the wearer’s eyes to become a lot more visible to other people! And so it is that with these modern-day materials, prescription lenses can be discovered not only on everyday eyeglasses but also shatter-resistant safety glasses worn to guard the eyes while engaged in certain industrial occupations.

One of the most important developments, flexible frames, was first employed on safety glasses which have to be rugged and reliable under any circumstance. Eyeglasses have come a long way since the old days of the pince-nez, monocle, lorgnette, and scissors-glasses. When in need of prescription eyewear, a wealth of options exists today for ease-of-use and wearer comfort.
