How come progressive glasses attain so much prominence in the world of eyeglasses? This must be a question that wears you down exhausted. Progressive glasses are characterized by lenses with a gradient of increasing lens power. Put it another way, in its uppermost part, the lens is used for distant vision, enabling wearers who are subject to myopia to catch sight of things in much farther distance than their impaired eyesight are capable of. Then the lens power is increasing by and by until reaching the maximum power at the bottom part, which, equipped with reading prescription, used for near vision. This special quality may somewhat resemble that of bifocal or trifocal glasses, but it outstrips all its rivals.
For another, a smooth and unencumbered viewing experience is characteristic of cheap progressive glasses, of which essential bifocal and trifocal glasses are in want. Traditional bifocal or trifocal glasses are inevitably enchained by the image-jump arisen from the uneven or unsmooth lens surface (usually in the bottom part of bifocal glasses are embedded a fragment of lens with full reading prescription. When someone wants to switch from distant vision to near one, the sudden image jump will cause certain discomfort). Yet progressive glasses are now free from all the nuisance brought about the image jump, since the lens power are in a smooth progression, thus enabling the wearer to see things clearly, unobstructed.
There is still another appeal that highlights cheap progressive glasses. That is the low price. It does not follow that all progressive glasses are cheap. The key lies in how to get them with a good bargain. Generally speaking, online optical brokers deal in a wide range of progressive glasses with different styles, designs and colors. Yet the price they are offering is often so fetching that you don’t want to let go of it. Luck would have it that you find a trustworthy online store, do not let the chance slip by your fingers. Clinch the deal with the most satisfactory price you can give. Cheap progressive glasses may come cheap in price but never in quality.
