Last week, when my wife went to her oculist’s for she had been suffering from eyes’ discomfort for a certain period of time. After eyes examination, he advised my wife to wear progressive eyeglasses instead of the common near-sighted prescription eyeglasses. He further explained that progressive eyeglasses are beneficial for people over 40 years old, who may have trouble reading fine print. Since the progressive eyeglasses are a bit more expensive then the bifocal ones, then my wife decided to purchase from online eyeglasses shop.
Progressive glasses? I have never heard of that before. Then I searched the internet for more answers. Progressive spectacle lenses , also called progressive power lenses, graduated prescription lenses, progressive addition lenses, are corrective lenses employed in eyeglasses to correct presbyopia and other disorders of accommodation to new eyeglasses. They are featured by a gradient of increasing lenses power. The progressive eyeglasses functions by starting at the wearer’s distance prescription, the full reading addition at the bottom of the lens, or at the top of the lens and reacheing a maximum addition power,.
Compared with traditional eyeglasses, progressive lenses can eliminate the visible lines of traditional bifocals and trifocals and hide the fact that you need reading glasses. Progressive eyeglasses have several obvious advantages.
First, progressive lenses are true “multifocal” lenses supplying a seamless progression of many lens powers for all viewing distances, rather than provide just two or three lens powers like bifocals or trifocals. With progressive lenses, you can look ahead to see your computer in the intermediate zone and drop your gaze downward to read and do fine work comfortably. It is also easy and comfortable for you to look up to see clearly in the distance or take a bird-view.
This is especially convenient for my wife for she is a calculator who buries her head all day in numbers and keeps on gazing at the computer. So we decided to purchase the progressive eyeglasses from online glasses shop since we have been accustomed to online shopping for it is reasonable in price and convenient and can save us a lot of trouble from going to the shops and malls.
We bought the progressive eyeglasses from a reliable online eyeglasses shop where we have shopped before. Because the April Day is imminent, the shop offers discounts for glasses frames and lenses from March 20th to April 10th. The online shop is www.prescriptionglassesonline.net.
