Eyeglasses are the most essential part of a shortsighted person. Without it is like living without an important piece of you. However, often while ordering eyeglasses, especially online, it can be hard to order one with the right measurements. Some glasses tend to slip off or do not sit right on the face. Hence, the right thing to do is to properly measure them and then order as every eye is unique and demand a correct fit for them. If not measured properly it can result in the glasses slipping off many times, not having the correct alignment especially in bifocal lenses, and sometimes putting too much pressure just because of the wrong fit of the frame. Buying eyeglasses is not something done regularly, so it is important to get the right one for yourself. Here are some important steps to look into and follow when ordering a frame for yourself. They will ensure the right eyeglasses for you.
Choosing the Correct Frame Size According to Eye Size
It is essential to pick the right frame size, especially when ordering glasses online. The correct measurement for different eye sizes are as follows: for small eye sizes, it is recommended for the frame size to be 40-48 mm. For medium eye sizes, it is recommended for the frame size to be 49-54 mm. It is recommended for a large eye size the frame should be 55-58 mm. Lastly, extra-large eyes frames should be above 58 mm.
Measuring the Lens Height
It is extremely important when choosing the right glasses to measure the lens height, excluding the frame. It is measured from top to bottom of the lens. The longest vertical distance is essential for bifocal lenses. Bifocal lenses contain two different prescriptions. A distant and close up. On the frame, there is a line in the middle for which the top part is for the distant vision and the bottom for the close-up focus. So it is necessary to have the correct measurements for that so one can conveniently use both with correct alignment.
Measuring the Bridge size
The bridge size is the distance between the two lenses. It is from the top of the inner frame to its bottom. It usually is 14 mm to 24 mm. This is also important when making bifocal lenses as it gives a correct measurement of where to transition to the other prescription.
Measuring the Bend of the Glasses or Nose Bridge Area
This if not chosen correctly, can prove to be a very big problem for people. An incorrect bridge fit, for example, a tight one will set the frame height as well as pinch at the nose, adding pressure to the eyes. Whereas a too loose bridge fit can result in glasses slipping too often hence resulting in uneasiness as well as discomfort. Thus it should be just the correct fit so that it does not add pressure which sometimes can lead to headaches.
Measuring the Temple Length
It should be measured fully from one temple length to the other, including the nose bridge bend as well. It is measured from the hinges to the end in a straight line. The length typically should be ranging from 120 mm to 150 mm.
Measuring the Frame Width and Height
The horizontal width and vertical height are to be measured from the outermost side of the frame.
Lastly, it is extremely important to align the glasses properly; they should be at the centre of your eyes. This means the lens of the eyeglasses should be at the exact centre opposite to the eyes. It mainly helps in letting you see without any extra pressure on the eyes.
One of the easiest ways to order glasses online is to use your previous glasses for measurements. It will allow for absolute accuracy. In many instances, the measurements are written inside your glasses. Typically in the temples. If your previous eyeglasses are a 100% perfect fit for you, then it will be very easy to compare the measurements. It is usually written in 3 pairs of numbers, for example, 48-20-130. This means that the eye size is 57, the bridge size is 20 and the temple size is 130, some glasses even have the lens height written. As a result, you will have all the information to order the glasses. Just like this, the nose bridge size can be modified to your desire if you own a very large or smaller nose frame and suffer from very tight or loose glasses.
These tips and suggestions for measuring your eyeglasses will surely prove to be very helpful and will help in ordering glasses even if one wants to place an online order.
