Heart-shaped face with angular glasses
The heart-shaped face is also a common face shape in daily life. This face shape is somewhat similar to the inverted triangle face shape. Generally, the chin is a relatively sharp face shape. For this type of face, the most important thing is to modify the cheekbones above the nose to highlight the slenderness of the chin. Therefore, it is better to wear a pair of angular glasses, which can effectively modify the facial lines and look more perfect.
Different Types of Progressive Lenses
The ground-view progressive lenses are designed for people who enjoy the outdoors. These lenses are supposed to provide a natural feel to your vision and reduce lens distortion. Ground-view progressive lenses allow better vision through the sides and bottom of the lens, so they give you improved vision when driving, using computers and looking downwards.
The standard progressive lenses are exactly what they sound like. They offer a wide reading area and have a longer drop between prescriptions and require a larger frame. However, they are less specialized than other lenses.
Can I use my prescription for contact lenses?
You cannot and should not use your glasses prescription to calculate your contact lens prescription. It's important to note that not everyone who needs glasses can wear contact lenses, and it's important to check them separately. Some people have sensitive corneas or other eye complications and never get used to wearing contact lenses.
Computer Protective Glasses
With the popularity of televisions and computers, electromagnetic radiation has become the No.1 killer of vision. The invention of radiation protection glasses is even more popular, and its market is also widely optimistic.
The lens design of the computer protective glasses has no side effects on vision. Refined with a high-tech vacuum ion coating, it can block 0% electromagnetic waves. The lens contains anti-radiation substances and has the function of absorbing positive charges. It can absorb low-frequency radiation microwaves and avoid potential eye fever, headache, fatigue, dryness, and other adverse symptoms caused by electromagnetic wave radiation. The penetration and absorption function of different light can resist radiation and glare, and the user will obviously feel clear and natural vision after wearing it. At present, there are mainly anti-blue lenses and anti-fatigue lenses, which can effectively prevent blue light radiation and relieve eye fatigue.
Disadvantages of bifocal glasses
The disadvantage of bifocal glasses is that the different areas are clearly spaced and the appearance is not beautiful. The medium distance is fuzzy, and the adaptation period is needed, there is a prismatic jumping phenomenon. The focal distance between the upper and lower lenses is different, with a clear dividing line. The main disadvantage is that when the line of sight moves from far to near, there will be interference like jumping, and the middle distance object image is blurred. Students can adapt to sitting still in a class by wearing bifocal glasses, but they can only wear glasses when they are in class or studying because of the inconvenience and even danger caused by the interruption of the glasses.
Advantages of Plastic Frames
Plastic frame material is mainly various types of plastic polymer materials. With the characteristics of impact resistance, suitable for athletes to wear. The plastic used to make the frames can usually soften under the condition of the heating, and some plastic frames can be fine-tuned without heating. The plastic frames are not allergic and lightweight, making them suitable for children and people of all ages. And because the color is rich, and there are many styles. They become the choice of fashionable sunglasses. Plastic frame cost is low, and the process is simple. Because of its lightweight, plastic glasses frame is not easy to allergy. Because of its color and material characteristics, they become the fashion personage sunglasses or decoration choice.
Why are titanium glasses expensive?
One reason is that the current titanium raw material cost is too high. The other reason is that the production of titanium frames is very complex. The production of titanium glasses requires special processing equipment, special welding technology, and electroplating technology, and many difficult and different processes, so it has a high production cost.
With the emergence of new titanium glasses production equipment and the improvement of production and processing technology in the industry, the price of titanium glasses will become lower and be available to a wider range of people.
