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.

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.

The other major disadvantage with store-bought reading glasses is that the prescription is the same in both lenses and the location of the optical centre of the lens is not customised.It’s very rare to find a case of exactly the same prescription for both eyes and almost everyone needs some astigmatism correction in their prescriptions.  Headaches and eyestrain can result from wearing glasses that are too far off your actual prescription or have optical centres too far away from the centre of your pupils.  The range of styles, especially in mens glasses, is also not as extensive as you’d get in an optician or via an Internet specialist supplier.   Protecting your vision is worth almost any price, so don’t jeopardise it and insist on properly prescribed and dispensed prescription glasses and sunglasses.

Could lens implants save your eyesight?

It may sound like science fiction but more and more people are opting to bin their reading glasses in favour of having artificial plastic lens implants inserted into their eyes instead. The procedure is becoming increasingly popular, especially amongst middle aged people who want to avoid the possible onset of presbyopia, or the deterioration of sight related to age. It sounds too good to be true, surely if it really works it could be the end to all our vision worries?

The idea of having your natural lenses taken out of your eyes and replaced with a small piece of plastic might not be one for the squeamish, but in fact the procedure works surprisingly well. The number of patients opting for the surgery has doubled since 2004, with most people reporting that the implants have made a huge difference to their sight, often meaning they no longer need to wear their prescription glasses at all.

So how does it work? Well, the natural lenses in the eye often stiffen with age, losing their ability to bend and focus properly. The implant procedure removes the natural lens from the eye and replaces it with an Intraocular lens, which uses the muscles of the eye to mimic normal lens movements and enhance the eye’s optical abilities. The procedure takes less than 30 minutes – the patient is given a local anaesthetic then a small incision is made to remove the old lens and insert the new one.

Lens implants as a preventative measure are not yet available on the NHS and the cost of the private procedure is not cheap, usually falling between £2,500 and £3,000 per eye. But when you think about it, being able to see both near and far without being dependant on glasses, escape from the discomfort of wearing them, or even being able to wear stylish designer sunglasses without having to worry about buying prescription lenses could actually be worth it!
