A man or a woman usually use eye glasses for vision correction or to protect eyes from ultra-violate rays. I used to use eye glasses since I am 18. I use it for the vision correction. I could not see an object at a distant clearly since 18. The object at a distant seemed blurred to me, then I contacted an eye doctor, he suggested an eyeglass of power -1.5D. Eyeglasses also named as glasses or spectacles.
I used a normal styled eyeglasses at first. Generally a eye glass consists of two parts, one is eyeglass frames and another is lenses. Eye glass frames usually made of plastic or metal. Lenses are made of plastic or glass. At the age of 18 I used glass as lenses. But now I use plastic as eye lenses. Plastic has many advantages over glasses because of plastic have less weight, reduce the danger of breakage, better transmission of visible light, greater absorption of ultraviolet light etc. Because of these advantages of plastic over glasses I started to use plastic lenses.
Now a days wearing glasses become a fashion and glasses come with greater design. Based on the design of glasses we can categorize it into various types.
1)Full-Frame Glasses: It is fully rimmed style which means frames are fully encircled the lenses.
2)Three-piece rimless: Three-piece rimless glasses have no frame around the lenses, and the bridge and temples are mounted directly onto the lenses. Frames does not encircle the lenses unlike full-frame glasses. It is also called rimless glasses. As there is three pieces (two by side and one in middle that connect the lenses) of frames, so it is called three-pieces rimless glass.
3)Semi-rimless glasses: In case of semi-rimless glasses frames partially encircles the lenses (commonly the top portion and the bottom position becomes open).
4)Fashion glasses: Plastic frames with designs.
5)Wood like: The frames are made of advanced plastic materials which look like wooden materials. It is more durable.
There are many companies that offer Wide Selection of Eyeglasses like glassesshop.com. They can offer any customized styles, frames, lenses, in fact whatever you want your glasses to look like.
