When people with high myopia wear glasses, everyone hopes that the lenses are very thin, but there should be a certain thickness for any degree. The reduction in thickness caused by the increase in refractive index is also based on the thickness of the lens itself. Even a 1.74 lens will definitely be thicker than a lens with a lower refractive index.
How should people with high myopia wear glasses to achieve the best effect
Everyone knows that the center of the lens is thicker while the edges are thinner. If you want thinner lenses, choosing 1.74 lenses is definitely not a problem. But how can a better effect be achieved? I will summarize several methods for you. 1. Data method: If you really want to buy a pair of glasses with good effects, don't rely solely on the refractive index of the lenses. This is far from enough. What we need to do is to try to grind off the thicker parts of the lens as much as possible, so that the lens will naturally appear thinner.
Calculation formula: [(lens width + nasal bridge width) - interpupillary distance]/2= cardiac displacement. The smaller or even negative the cardiac displacement is, the thinner the lens will be. The interpupillary distance here is the true interpupillary distance. If the center of the lens corresponds to that of the pupil, there will be more areas of the lens that can be cut. The corresponding thickness will naturally become thinner.
The thicker the frame of the metal plate is, the greater the thickness it can cover. It looks a little thin. Besides, because the lenses are too heavy, the wooden frame will not press against the bridge of the nose.
3. Frame color selection: The frame color should be similar to that of the lenses, suitable for customers with high requirements for prescriptions. For example, transparent colors. When the lenses are polished and brightened, the color of the lenses and frames can be confusing. It can also make people look slimmer.
4. Choosing smaller frames will make the entire pair of glasses look thinner. Because the middle of the lenses is thinner and the edges are thicker, a smaller frame will make the glasses look thinner.
5. Processing method: During the processing, we always make a small cutting edge to reduce the thickness of the lens. If this Angle is cut too much, it may cause the white circle to enlarge. If it is cut too little, the thinning effect cannot be achieved. You can decide based on your personal preferences and tell the processor that you can do so.
