Know More About Glasses Sizes Before Buying Eyeglasses
Though more and more people are now suffering from vision errors of certain kinds
, their lives are never greatly affected, mainly because they can find some ideal rectifying eyeglasses. Usually, these eye wear can bring wearers perfect vision if accurately prescribed. However, before buying eyeglasses, people should know something more about eyeglasses sizes if they really want to buy a pair of highly personalized eye wear. Glasses sizes might be strange for common people, for these data are seemed to be something professionally for opticians. However, knowing them can really benefit wearers a lot.
Usually, glasses sizes are composed of several numbers, which can accurately reflect the real situations of the glasses. For example, a pair of prescriptions purchased from firmoo.com reads like this, GU120 600 52- 20- 140. GU 120 refers to the model number of the glasses; 600 refers to the color number of the glasses; 52 refers to the horizontal width of the lenses; 20 equals the distance between two lenses, or distance of bridge; 140 refers to the width of one temple. Of course, these numbered are measured in millimeter rulers. Usually, all these numbers should be used together, for they are an organic set and can never be separated. Each set has its own features and is suitable for certain wearers.
Therefore, these numbers are professionally measured and wearers are suggested to ask some eye doctors for help, though some of them can do it themselves. Eye doctors are more professional in measuring these data and the sizes measured by them are accurate.
These data are relatively stable and will seldom change on a certain wearers. Therefore, wearers can benefit greatly if they can remember these numbers. No matter what kind of eyeglasses they buy, RX glasses,
clear lenses glasses, sunglasses, etc, they can quickly tell the opticians what their
eyeglasses sizes are. The merits of knowing these sizes are not very evident if people buy from real optical stores, for the opticians and optometrists are at service at anytime. They can be well highlighted if they want to buy from online shops. Though buying eyeglasses online is time saving and convenient, the premise is buyers should know some specific data about their eyes. Therefore, if wearers know these sizes, they can directly deliver them to the retailers instantly.
Of course, people should consider something about appearance after knowing glasses sizes. It is true that these sizes can play decisive role in deciding what a pair of eyeglasses will be alike, but people should also know what they are looked like with these eyeglasses- are they too larger or too small, are the colors suitable for them, etc.
