Bifocals are some of the most important choices for people with both near vision and far vision problems. And almost of those eye problems can be completely solved by them. However, there are still some demerits in those glasses and wearers want to use much advanced products. Thus, the emergence of progressive bifocals has made people’s dreams come true. Here is going to introduce some of the most representative members among them.
In addition to common progressive bifocals, there are still progressive bifocal sunglasses that can be used as accessories and vision correction. Those sunglasses can always ensure the following several points- wearers’ eyes and skin around eyes can be greatly protected; wearers will enjoy great and natural vision clarity with them; wearers can also enjoy the latest fashion in the industry, etc. Therefore, many people who often work or walk outdoors love to buy those unique sunglasses.
Another very popular sunglass, called progressive bifocal reader, is also very popular among people who love to read under the sun. It can help filter out some harmful and bothering lights and highlight other wanted lights. Or in some other cases, it has magnifying effects, too. Therefore, wearers can enjoy great vision clarity without worrying any damage will occur to their eyes.
Progressive bifocal contact lenses can also be found in the market. Theoretically speaking, bifocals and other multiple focal glasses require highly on lens size. Therefore, if the size is not large enough, such glasses can never be made. Therefore, making contact lenses with multiple focuses seems impossible. However, after the great efforts of many designers and professionals in the industry, such contact lenses come into being ultimately. It seems that those lenses are almost the same as other ordinary lenses, but they are really outstanding in function and appearance.
Of course, many other nice progressive bifocals are also available in the market. But they are not as cheap as other glasses. Generally, progressive bifocals cost about 50% more than other common glasses in the same stores. But people can get them from some particular retailers who may provide discount to some extent. For example, bifocals from online vendor are relatively cheaper than from real optical stores.
In a word, progressive bifocals are the best alternatives for people.
