Why are eyeglass frames are so expensive?
Good frames and bad frames are very different just in how they feel. The bigger the brand company, the more money it invests in the design, research and development, production equipment, and equipment of the lens frame every year, so as to improve the wearing comfort and improve the combination and precision of the lens. Even if for the general assembly line, the processing process is also very complicated. The most expensive things to make by hand are labor and time.
Reading Glasses
At present, there are two prescriptions for reading glasses. One is to adjust the power of glasses with clear objects at close range, plus 1/3 of the power for adjustment. The other is to use low power that can see close objects clearly. The practice of many elderly people has proved that the latter one is better between two methods.
Data obtained by computer optometry alone may not be accurate.
The first thing is to go to the optometry store, or the hospital to do a glasses degree test, namely to get single optometry. The precision computer optometry has errors, and computer optometry is only used to measure separately monocular degrees. What we need is the best visual effect of the binocular match, so the exact prescription needs to be carefully confirmed by comprehensive optometry. Optometrists will ask everyone to try on the insert lenses again, and even need to repeatedly try on several degrees of lenses, in order to finally determine which degree is the most appropriate, because even the professional optometry data is only a rough range, only based on the data of glasses is not necessarily suitable for their own. You can use a focometer to measure the actual parameters of the glasses you are wearing. If you are still unsure of your prescription, it is recommended to fax, mail, or mail your prescription to the merchant when placing your order.
The length of the temple is important.
The glasses should fit snugly over and behind the ears. If they clip behind the ear, mostly, the arm might be too short. The arms of your glasses should be straight back toward your ears, touching only the side of your head, just in front of your ears. If the temple bends too soon, it pushes the glasses under the nose, putting too much pressure on the bridge of the nose and causing a headache.
Glasses Size - Lens Width
Lens width is the width of a lens, measured in millimeters, from one side of a lens to the other side of that lens. This is the most important measurement to make sure the frame fits your eyes.
Choose blue light blocking glasses with guaranteed quality.
Because blue glasses is a kind of special care, which requires quality assurance. Wearing the unqualified glasses for a long time not only failed to protect his eyes against the blue glasses but can also lead to decreased vision. In severe cases, physical disorders can occur, causing dizziness, headache, and so on. So choose a big brand, guaranteed blue light blocking glasses, which can truly protect your eyes.
Why do people like wearing rimless glasses?
Rimless glasses are not heavy in weight, so they are suitable for all skin types. Even if you have oily skin, because the glasses themselves are not heavy in weight, they are not easy to slip off. Since rimless glasses have no frames and are made of memory titanium alloy, they are not heavy, which greatly alleviates the pressure on the bridge of the nose and eyes and makes them more comfortable to wear. And because there are no frames, the wearer has a wider field of view.
