Understand the impact of frame selection on the lens
Frame size is an important consideration when using progressive lenses because some progressive lenses work better in frames of different sizes. Since progressive lenses allow you to see at all distances, it's important that the whole range of vision fits within the frame. Therefore, very short lenses and larger lenses are not suitable for progressive lenses.
Why are titanium glasses so expensive?
Pure titanium can guide the electron wave to produce ions so that the current tends to ionize, and positive and negative ions can reduce the harmful effects of the body's biological current chaos caused by electromagnetic waves. To the human body, it has a great health care role. It avoids fatigue, muscle stiffness, soreness, and other symptoms or problems.
Recycling glasses is one of the projects.
Eyewear recycling is one of the Lions Club's most high-profile and well-known programs. Lions Club has been collecting eyeglasses for over 80 years and Vision Recycling has been the official program of Lions Clubs International since 1994. Refractive errors can be easily corrected by wearing glasses, but millions of people in developing countries still do not have this basic eye care. Lions' collection of glasses enabled many people in these countries to see clearly for the first time. Lions also collect used hearing AIDS!
The clear frame is paired with wire glasses.
Compared to traditional chunky glasses, gold-rimmed glasses have less color saturation, so they are almost skin-neutral. Gold-rimmed glasses and clear frames are similar in style but more decorative. The geeky-chic style has become popular since the Gucci fashion show, which started with large frames. Who says you can't be stylish with glasses?
Production technology of progressive lenses
In addition to the evolution in design, the production technology of progressive lenses is also constantly improving: the most representative one is the free-form technology. The emergence of free-form surface technology makes the production more flexible and rapid and can realize a more personalized design. For now, progressive lens design is done on the inside surface of the lens by a computer-controlled lathe, as if a master engraver could carve a piece of stone into a work of art.
Glasses for heart-shaped faces
This type of face has a wide forehead, broad cheekbones, and a pointed chin. It is called a heart-shaped face. The upper part of the heart-shaped face is relatively wide and flat, and the lower part of the line is uniform and smooth. The facial line, the proportion is very soft, giving a person an intimate intuitive feeling. Wearing longer or rimless glasses for this face shape will make you look cute.
Can you wear blue light glasses while driving?
The damage of blue light has a cumulative effect. The longer the exposure time is, the more serious the damage of retinal cells will be, which will eventually lead to irreversible damage of the structure and function of the retina. Once the retina has permanent damage, degeneration will directly affect the metabolism and function of photoreceptor cells, resulting in vision loss. It depends on the glasses you're wearing. The function of anti-blue light glasses depends on the material of the glasses. Some blue light glasses have a special anti-reflective coating, which can reduce glare. These glasses are definitely helpful when driving at night.
