The Ease And Comfort Of Prescription Eyeglasses
Go to: Previous Article Next Article
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 a lot 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 a lot 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 obtainable for casual use at ordinary prices! Moreover, thanks to the web, low-cost eyeglasses can be readily purchased.
However, it is a great 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 low-cost prescription eyeglasses.
