How to measure the size of glasses? Measure the old frames.
In order to measure frames correctly, you need to know a few basic dimensions:- lens width - this is the horizontal diameter of the lens measured at the widest point. It is sometimes called "eye size" by optometrists,
- The height of the lens is the maximum vertical length of the lens. It is often referred to as standard. It's usually about 32-38 millimetres,
- Bridge width - is the horizontal part of the glasses over the nose between the lenses. The part that connects the glasses - from the lens to the lens (the nose width is about the same as the nose width) - is measured. It ranges from 14 to 24 millimetres,
- length of temple - measured from hinge to tip behind ears, including bend. In this case, there are three most common standards: 135 mm, 140 mm and 145 mm.
Ray Ban - how to choose the size of frames using a credit card?
The method of measuring the eye using a credit card is a method proposed by Ray Ban, among others. Why a credit card? It's simple. Its width is similar to the width of standard lenses. So if you want to buy your first pair of glasses online, check out the Ray Ban sizes that are right for you. You must do the following:- take a regular credit card and put it on your face,
- Stand in front of the mirror and place the edge of the card in the middle of the nose (place the card so that the shorter side of the card is under the eye and the longer side along the axis of the nose),
- if the other edge of the card is on:
- the height of the end of your eye, then your size is standard,
- if it goes beyond your eye, you are wearing a small frame size,
- however, if the edge of the card does not reach the end of the eye, it is a sign that you are wearing glasses above the standard size of glasses.
What do you mean by "size" in an online glasses shop?
Sizes of sunglasses and prescription glasses are usually given in the same way. Ray Ban places this information on the inside of the temple. There you will also find information about the UV filter (in the case of sunglasses), the serial number and the name of the series. An example of a glasses designation is:RB (Brand name: Ray Ban), 2140 (serial number/model code), WAYFARER ORIGINAL (serial number/model name), 901 (model designation code), 50 (lens diameter), 22 (bridge width), 150 (temple length), 3N (lens filter designation).
So what do you mean by "size 54"; or "size 58";? A parameter called size, which can be found in the product data sheet in the online shop, is the width of the lens measured in millimetres. For example, 52 glasses have a lens width of 52 mm and 55 glasses have a lens width of 55 mm. In addition, the description of each product must include values such as the width of the sternum or the length of the temple (usually in that order).
Now you can buy frames of your own size without leaving your home. Remember to buy sunglasses and prescription glasses from reputable companies. It is a guarantee that they have the necessary protection and approvals and that they are healthy for your eyes.
