When I was three years old, I was sent to an art school to learn painting. Honest speaking, I liked it very much so I spent a lot of time in painting. Because I studied so hard, I got a good result finally. Every year, I got scholarship and my teacher spoke highly of me. I felt very glad. And then, I studied harder and harder and was much fonder of it.
However, a serious related problem came to me consequently. As I spent a lot of time in staring at the drawing board for a long time without break, I suffered from myopia three years later. That is to say, I had to take some measures to deal with it.
Key to myopia. There are three ways to solve, that is, wearing glasses, wearing contact lenses and doing eye operation. Since I was so young at that time, wearing contact lenses and doing eye operation were not permitted, I had to go to an optical store to select one pair of frame glasses with my mom.
At first, I was reluctant to go there because I didn’t want to wear glasses. But I had to. After checked the vision condition at an eye care center, I got my prescription. Then I go to a glasses store. When I stepped into the glasses shop, I was astonished by the eye wears in a variety of styles. I tried several pairs and didn’t know how to choose. Finally, I got a favorite pair in the instruction of the optometrist. From that time, I began to accompany with the glasses.
Since I found the glasses are so attractive, I started to notice different kinds of glasses, including prescription glasses, non prescription glasses and sunglasses. I have to spend a sum of money on eye wears every year.
Several days ago, I found a pair of red glasses online which I like so much. The frame is manufactured with mixed material and lenses in PC. The price is only 39 dollars. What’s more, fortunately I got a voucher worth 20 dollars. Without hesitation, I got it. Now I am wearing it.
If you are willing to get a pair of wonderful glasses, it is time to take actions. Perhaps you will be the next lucky dog to get the free glasses.

The first pair of eyeglasses was invented in the 13th century for people to magnify objects they wanted to see. Using convex lenses, it was used to compromise farsightedness, which was the inability to see items nearby clearly. Later in the 14th century, nearsightedness was also correctable by using concave lenses. This kind of lenses enabled those patients to focus on objects in distance. During the centuries after the invention of concave lenses, people with farsightedness or nearsightedness were able to get normal vision by wearing convex or concave eyeglasses.
The invention of bifocal lenses
However, a third group of patients occurred in the 1700s, exemplified by the invention of bifocal eyeglasses by Benjamin Franklin. This new form of glasses can correct both vision errors for both near and far. Having difficulty in focusing on objects both near and far, Benjamin Franklin had also to travel a lot. During his travels, reading was a regular activity. The problem was that a single pair of concave glasses was not enough and he was forced to swap eyeglasses frequently. Bothered by continuous eyeglass switches, he combined two lenses into one lens. Widely known today, a bifocal lens has a top part for distance vision and a bottom section for viewing close up things.
After several centuries’ development, bifocal eyeglasses are quite popular now. It is estimated that more than half of the individuals who use corrective eyeglasses are bifocal users. They are currently widely used by people who need more than one kind of visual need. Some people may notice that the need for bifocal eyeglasses is increasing as they age. It is true that bifocal glasses are mainly for the old. In most cases, people who wear single vision lenses will switch to bifocal lenses when they enter their 40s. For most new users, it may take some time to get adjusted to a bifocal pair of eyeglasses at the beginning.
Proper use of bifocals
The standard design of a bifocal lens is that the top half is incorporated with a power for distance vision and the bottom half another power for close-up view. Well, this design is significantly different from any kind of single-vision glasses. Myopia or hyperopia glasses have only one focal point, which means that there is only a uniform power across the whole lens. A problem commonly reported by new users of bifocals is that the vision becomes uncomfortable or even headache will be caused. In some cases, peripheral vision especially the vertical vision will be limited because of the power division in the middle of the lenses. Both the near vision section and the distance vision section are narrowed. This is an unavoidable condition for every bifocal user. Furthermore, there are still additional requirements on proper bifocal use. While it is simple to see through myopia or hyperopia lenses and get clear images, bifocal eyeglasses require the user to tilt his or her head slightly up to see objects in the distance and look down mildly to get clear close-up vision. These tips originate directly from the unique lens design described before.
Although we pay attention to our vision problems in recent years, the number of people who suffer from myopia is still increasing. As a result, more and people are wearing prescription glasses. However, many people hold wrong opinion on prescription glasses. For example, a lot of people think that the prescription glasses are to cure the myopia. As a matter of fact, myopia can’t be cured by glasses. The prescription glasses are used to correct myopia. They are just the vision correction aids. If you want to recover good vision condition, doing eye operation can achieve it.
The so-called myopia, or shortsightedness is a refractive defect of the eye in which collimated light produces image focus in front of the retina when accommodation is relaxed. Or more simply, it is a condition of the eye where the light that comes in does not directly focus on the retina which is in the back of the eye. Because of this, the image that one sees is out of focus.
Eye care professionals most commonly correct myopia through the use of corrective lenses, such as glasses or contact lenses. It may also be corrected by refractive surgery, but this does have many risks and side effects. The corrective lenses have a negative optical power which compensates for the excessive positive diopters of the myopic eye.
From the current optical market, the framed glasses are composed of frames and lenses. To correct the vision problems depends on the lenses. There are several types of lenses including glass, resin, PC lenses. Different materials have different features and advantages. The contact lenses are quite hot in recent years for they relieve the burden of the nose and increase the sense of beauty.
No matter for the framed glasses or the contact lenses, it is necessary to have an overall and professional visual check before, that is to say, to know the vision condition carefully. What’s more, for those who wear framed glasses or the contact lenses, it is essential to pay enough attention to habit and eye health in daily life and sustain a good vision condition.
