No one can stop the time that goes by day after day. Unconsciously, we are growing older along with the hair becoming gray, skin becoming wrinkled and eyesight becoming blurred. How can we enjoy our lives when hanging out with huge pleasure but looking at everything unclearly? Maybe, we have a pair of Presbyopic glasses, but how to prevent the strong light and how to do the quick vision change to the near objects from the far objects are big problems. Wearing two pairs of glasses or more seems impossible, for our noses can’t bear that weight and it’s quite uncomfortable. As the technology develops, glasses are combined with many advanced technical elements and they can really meet people’s need. Bifocal sunglasses, trifocal sunglasses and progressive sunglasses are the latest technology products. They have two or more focal points with the function of protecting eyes from sunshine, so we need only to wear one pair and to go out for fun. Besides, when compared with the bifocal and trifocal sunglasses, progressive sunglasses suit one better.
Progressive sunglasses avoid the image-jumps and people must enjoy the surroundings more. According to the literal meaning of bifocal sunglasses mentioned above, they have two different focal points. Due to that particular design, people can see the distant objects through the upper part of lenses while seeing the near areas through the under part. However, a distinct line is located between the two parts which make the transition sharp enough, thus induce some headache and discomfort. So do the same to the trifocal sunglasses. But progressive sunglasses conquer the above problem. They have continuous focal points. From the top lenses to the bottom lenses is a range from a maximum addition power to the full reading addition. This improvement makes the quick vision change out of headache and feels more comfortable.
The types of progressive sunglasses vary a lot. Anyone can find one pair suitable for himself. But don’t go to those non-formal shops, because the glasses they offer may make your eyesight become worse. Instead, you are suggested to go to see a professional oculist and have some necessary test. After getting your exact eye degree, choose a reliable Optician, and then he will get the right lenses for your eyeglasses. In addition, you can choose your most favorite frames and you can ask for some decorations like diamonds on the frames if you like.
As the progressive sunglasses are a kind of relatively new creation, there are not many people who choose to wear them. But we believe they will be quite popular some day because of its obvious advantage and comfort wearing.
I hope every old people with eyesight problems can have a chance to see the splendid world clearly again. I wish progressive sunglasses make a great contribution to the world.
