What Do the Numbers on Glasses Mean?
In this section, we will show you the glasses numbers meaning. These numbers on glasses frames are the measurements that indicate and describe the size of your eyeglasses frames, specifically:
- The eye size number (it is the size of the lenses on your frame).
- The bridge size number (the distance between the lenses).
- The temple length number (it is the size of that part of your eyeglasses frame, which rests upon your ears).
The three numbers mentioned above are the key measurements that describe the glasses measurements of the frames in eyeglasses. For example, you will see three numbers like 51-17-145 at the temple of your glasses. These numbers help the optician to choose the best-fitted frame for your head size and facial features.
All of these three numbers are measured in millimeters. These variations in frame numbers are fitted by a skilled optician so that it should be best fitted, be comfortable and look good on the appearance.
How to repair rimless glasses?
First, insert the wire into a small hole in the glasses near the bridge. Pass it in and out near the bridge, then repeat the process on the other side near the temple. Once you have the thread locked, you can place the lens. Insert it into the frame and place the wire in the built-in groove. Tighten the wire so it holds the lens perfectly, then trim it to the left. Reinsert the lens into the rimless glasses. Do not try to force it back in. The best way is to cut the wires completely and replace them with new ones. Use the same process as replacing wires. To prevent glasses from popping out, tighten the wires regularly.
How to protect your contact lenses?
When wearing contact lenses, do not drop any eye drops, and only use a special moistening solution for contact lenses. In daily life, we recommend that dry eyes can be relieved with lubricating fluid, but we do not advocate frequent use of lubricating fluid, so as not to make the eyes become dependent on lubricating fluid. The right way is to do blink training. The ingredients contained in the eye drops will remain in the lenses, which will cause certain damage to the eyes and pollute the lenses. Some eye drops can make the lenses tinted after use, which will affect the transmittance and a refractive number of the lenses and make the vision blurred. Ladies who need to make up should wear contact lenses before making up. When removing makeup, remove contact lenses before removing makeup, to avoid the makeup sticking to the lens and damaging the lens and eyes. Lenses should not be lent to others to avoid cross-infection of eye diseases. You can't wear contact lenses while swimming or bathing.
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.
What are the advantages and disadvantages of bifocal reading glasses?
The advantage of bifocal reading glasses is a large field of vision, and they can be used with the same pair of glasses to see far, near. The cost is lower. But different areas have obvious intervals, and the appearance is not beautiful. The middle distance is fuzzy. They need to adapt to the period. Bifocal reading glasses lens is divided into two parts, and the degree of the two parts is not the same. The upper part is the mother of the flat area to see far, and the next part is the child of the reading area to see near. There is an obvious interval. The appearance is not beautiful. There is no transition area between two different areas, so its vision is fuzzy, easy to produce a 'jump image'. Long-term wearing will make people dizzy or fall down when climbing stairs.
Lions Club
Lions Club is a service organization with over 1 million members worldwide. Known for the work to improve the lives of the visually impaired and prevent avoidable blindness, they are proud to serve their ongoing efforts by providing unique and influential programs and grants. One of their missions, Lions Recycle for Sight, helps those who desperately need eye care and glasses that they either can't afford or don't have access to. The Lions Club accepts donated prescription glasses, sunglasses, and card readers, but only sunglasses and card readers can be distributed in the U.S. All other donations go to help individuals in developing countries.
Price positioning
In terms of positioning, it should conform to students' purchasing behavior, that is, the middle and low-grade products are mainly used, and the appearance requirements are stylish and novel. In addition, you can be properly supplemented with a small number of high-end products, because your market is not only the school but many residents around.
