Before purchasing a pair of prescription eye glasses, you have to know all the materials and choose the one you want.

More and more people tend to purchase products online. Busy people are attracted by the efficiency and convenience of shopping from the comfort of their own home. We don’t need to walk through big shopping centers. On the contrary, we will have more time for picking the products we want and with a simple click we can complete our orders.

When it comes to online-shopping，there is obviously lots of difference between E-shop and real shop. Although E-shop is not an entity，the goods are displayed in the form of some pictures on the website in order to make people know more about the products without actually touching them. The real shop has everything on display, which we can touch, however, we must leave our homes to do this. 

Therefore, people who are busy can’t spare time to shop, so they take advantage of shopping online.

Although it is convenient to buy products online, it may not satisfy all of our shopping needs. For example, buying eyeglass online is not as easy as purchasing clothes online. People only look at the images of eyeglasses on the Website，getting a good impression of the appearance of the eyeglass frames.  

However，we cannot know whether a pair of eyeglass will fit properly, because it is not like buying clothes which we can buy according to size.  It is difficult for people to know the right size of eyeglass frames for themselves，because there is great difference in individuals heads and eyes.  

Therefore，we need to consider carefully when buying eyeglass online.

Even though we have to face some potential problems in buying eyeglass from the E-shop，busy people have no time to visit the traditional optical shop, so we must find a compromise between saving time and finding eyeglasses that fit correctly. 

But is there the way to resolve this dilemma？

We should read the detailed description of the eyeglasses that the seller provides.  

This will not guarantee that there is a way to tell you how to choose the right one. Telling the seller your correct prescription can make sure that you will get the right lens and will be able to see everything clearly。The next problem，which is a difficult challenge，is to find a frame that fits your face. When you receive the glasses in the mail and find out they do not fit, you must exchange them for a pair that will fit.  This could waste much more than going to a traditional optical store directly.

In conclusion we could say that e shopping may not save time. 

But，the final decision is yours.
