Online eyewear stores are always praised that they can offer a larger inventory or stock than traditional optical shops. This is really true that a large-sized online optical store will probably keep thousands of different eyeglasses. Taking framesdirect.com for example, the website claims that it is the world’s largest online eyewear store by stocking one hundred thousand eyeglasses online. Of course, not all online eyewear stores can maintain such a scale. But it is undeniable that those eyewear shops on the Internet are more capable of showing thousands of eyewear products than local sellers. Eyeglasses are differentiated mostly according to frame types. With a large inventory of eyewear products, it is important for an eyewear store to categorize its eyeglasses frames online. Efficient classification ways are beneficial to both the vendor itself and its customers. From the seller’s point of view, well-organized eyeglass frames always lead to efficient business. And at the side of customers, efficiently grouped eyewear products enable them to search out favorable one or ones without much effort. For instance, they can simply use Google and type a key word or phrase which is closely associated with the ways to classify eyeglass frames.

During the past years, there are actually common ways adopted by online eyewear stores to categorize prescription glasses . It is easy to find the following categories of frames. Gender is commonly used to group all eyeglass frames into men’s, women’s and unisex ones. This approach to classification is actually based on different tastes between men and women. In general, women’s eyeglass frames are usually designed to present thin temples and small lens frames. For most men, it is more common to choose formal and classic frames. Frames with slightly thicker temples are still acceptable. And unisex eyeglass frames usually have a moderate design. Another way for customers to search eyeglasses is based on frame material. While metal and plastic frames are the two main categories, there are still some detailed key words associated with frame material, including titanium, mixed material, memory metal, Monel and so on. Just as the old saying goes, everything has both advantages and disadvantages.

According to frame style, glasses online  are usually divided into full frame, semi-frame and rimless ones. In addition, some online stores still offer a special category of sunshade models. Sunshades are frames without any temples so that they can hardly fall into any of the main three frame types.

But purchasing a new pair of glasses is not just a matter of getting a pair of glasses which corrects your vision. The style of the glasses can completely change the way you look like. Actually, eyeglasses have now become a high fashion accessory.

Glasses styles change every year, just like every other fashion, but the main fact based on what you choose your glasses is the shape of your face. Face shapes can be classified roughly into six categories: round, oval, square, oblong, diamond, triangular and heart shaped. Different eyeglasses frames will go with different face shapes.

Round shaped face: Round shape people have full cheeks, rounded chin with few angles and the width and length of their face are in same proportions. Their five sense organs are highly centralized. What they should avoid is to make their face look rounder. So they can choose glasses online in any styles but round frames. Both rectangular and horizontal styles can make faces appear longer and thinner.

Oval shaped face: People with oval face have a balanced proportion on their face. Their chin is slightly narrower than forehead and cheekbones are high. Generally speaking, most frame shapes will go with oval faces as long as the frames are not too small or too large.

Square shaped face: People with square face usually leave others the expression of rigid characters because of their angular face. So oval and round frames that moderate angles of the face. Oval and round frames will be the best choice.

Oblong shaped face: People with oblong face should wear broad frames that help create a shorter face in case that they will create the feelings of too narrow or too pungent.

Diamond shaped face: Diamond face people’s chin appears to be small and their cheekbones are dramatically wide. The glasses they choose should help to cover this. Oval frames and rimless styles can achieve this purpose.

Triangular shaped face: People with triangular face have narrow forehead and eye line that widen at the cheeks and the chin. Their top choices should be semi-rimless frames that draw attention to the upper face and balance the width of the jaw.

Heart shaped face: People with hearted shaped face should wear narrow, round frames that soften their upper face or they can wear bottom-heavy frames that make the lower face wider.

Above are the tips about which face shapes fit which frame shapes. But the best way is to go and try them on. You should try as many styles as possible and have an accompanier who can tell if the glasses you try on look right.

Glasses are optical instrument consisting of a pair of lenses for correcting defective vision. Glasses used in vision correction include myopic glasses, hyperopic glasses, and presbyopic eyeglasses, as well as astigmatism glasses. Glasses are not only tools to protect eyes, but also the decorations.

 

Some believe that for people who are with the relatively low degree myopia or just being short-sighted are pseudo myopia, glasses are not necessary. There are also concerns that if they are pseudo myopia, wearing the prescription glasses will make myopia true. Nevertheless, experts point out that as long as the degree of myopia has been detected, even if only 100 degrees, it is the so called true short-sightedness that need the help of glasses rather than pseudo myopia. Wearing glasses can help those who are shortsighted to avoid further deterioration of visual acuity, thus stop the exacerbation of myopia.

 

Some people, however, are with a good eye while the other eye has reached the degree more than 100. These people refuse to fill a prescription and abuse his good eyes. In fact, such a visual difference is equivalent to one foot in a high-heeled shoe while the other one is in flat shoe which is very negative to the eyes as well as health.

 

Moreover, there is no need to wear glasses online all the time. Some people think that wearing the glasses will harm their beauty and do not wear them usually, but on the other hand they worry that this will add to the short-sightedness. However, experts give a definite answer that the time you wear glasses do not necessarily decide whether your eyesight deteriorates or not. Generally speaking, if you look at something (for example, to see distant things) relatively unclear, you must wear glasses; but if you can see clearly when reading a book, you need not to wear glasses.

 

All in all, glasses should be chosen and worn in the principle of making your sight clear and comfortable.
