A clear frame leads the way.
Clear glasses are almost always dominated by large frames. The big frame is an acceptable frame for any face shape. clear rimmed glasses are on the rise, so buy a pair before they hit the streets. Some are full of clean feeling, and the lens frame is slender and elegant. Some models are simple and versatile, suitable for all kinds of fashion styling. Light and fashionable, the collocation of clear frame and aureate glasses frame, is rich high-quality goods feeling.
How can I measure the frame size?
Use a ruler to measure the glasses you used to wear comfortably and record the width of the frame and the total width in front of the frame. And compared with the frame width of the selected frame and the total front width of the frame. Frame width size difference of one or two millimeters does not matter, and the total front width of four millimeters does not matter. You can use a ruler to measure the approximate distance between the temples. Usually, the width of the inner side of the frame is the same as the temple value or about 3MM larger than the temple value.
What difference do mono-focal glasses and multi-focal glasses have?
A mono-focal lens is a lens with one focal point. Usually, the myopic far-sighted presbyopia that we see belongs to mono-focal glasses. There is only one diopter on one lens, and this is the single focal point. Multi-focal glasses are lenses that have multiple focal points, that is, multiple diopters. Both mono-focal glasses and multi-focal glasses are visual correction tools, but mono-focal glasses can meet basic vision needs, like fatigue relief, control of depth of diopters, and focus on different distances such as the need to see far and near.But because there are many different diopters on a multi-focal glasses lens, so the elderly can not only see far after wearing. When they see close distance, they do not need to take off glasses or wear reading glasses. Wearing multi-focal glasses is not easy to fatigue.
Understand blue light correctly.
Blue light has been shown to affect the body's circadian rhythms, with too much exposure to it late at night from gadgets such as mobile phones disrupting a person's ability to fall asleep. Therefore, it is recommended that people limit screen time two to three hours before bedtime and set their devices to night mode to reduce glare, relieve eye fatigue and minimize blue light at night. However, as we learn more about blue light, not all of it is bad for us. Blue light has been found to play an important role in maintaining health, such as regulating the secretion of hormones in living organisms. Blue light helps prevent reduced night vision and has been shown to benefit refractive development in adolescents and minors.
Are the glasses purchased online of good quality?
Always, there are some people who question online shopping, whether the quality of the glasses purchased online is up to standard. Then I have to ask, is the quality of the glasses bought in the physical store good? Most people do not have the ability to judge the quality of glasses. It can be said that they decide which to buy based on an inexplicable idea. Therefore, for those who do not understand glasses, the quality of the glasses purchased online is not a question we should consider. In my personal experience, there has been no quality problem with the glasses purchased online, and for the same price, the glasses purchased in physical stores are much worse than those purchased online.
The glasses slid up your nose.
Although glasses often slide up your nose and pushing them up can be annoying, it's easy to pull them tight. If your nose frame is metal, use your thumb to shrink the nose pad until the frame no longer slides. If you have plastic frames, soak the arm in warm water for 30-60 seconds, then apply slight downward pressure to the end of the arm. This will make it fit more behind the ears, which will tighten the overall fit and prevent slippage. If tightening the frame doesn't work, try using eyeglass wax to stop it from slipping.
How to Tell If Your Progressive Lenses Are Correct?
When you can’t read with your progressive glasses, you can try this way. Hold something you want to read in your hands and lower your look with your eyes. But please note do not move your chin down as you look down. Then look down at something to read but do not lower your chin. Look at something you want to read. Rotate your head to the left and right and right with one eye at a time. If you can read in a rotated position, the reading zone is out of place. If you can’t read at all, the progressive glasses may be wrong.
