Metal Eyeglasses

Whether you like classic looks or prefer rectangular and functional things, all metals will look new in 2021. Combining the trend of super large frames, you get a big round metal frame. These styles are not heavy and fit all face shapes, from round to square, and anything in between.


Advantages of progressive lenses

1. The appearance of the lens is like a single vision lens, and the dividing line of the degree change cannot be seen. Not only is the appearance beautiful, but more importantly, it protects the age privacy of the wearer. There is no need to worry about leaking the age secret due to wearing glasses.(https://www.koalaeye.com/collections/progressive-glasses)

2. Since the change of lens power is gradual, there will be no image jump. It is comfortable to wear and easy to adapt.

3. Because the degree is gradual, the replacement of the adjustment effect is gradually increased according to the shortening of the short distance. There is no adjustment fluctuation, and it is not easy to cause visual fatigue.

4. Clear vision can be obtained at all distances in the visual range. A pair of glasses meet the use of long-distance, near use, and various distances in between. It is especially good for teachers, doctors, music workers, and computer operators because these people not only need to see far and near objects clearly, but most of the time they also need to be able to see objects at intermediate distances such as blackboards, piano scores, and computer screens. This is not possible with lenses other than progressive lenses.

5. At present, both internal and external ophthalmologists agree that young people should wear low-degree convex lenses when reading and writing to reduce near-use adjustment, thereby alleviating or preventing the occurrence and development of myopia. This gives the progressive multifocal lens a new meaning and mission. Physiology found that excessive use of the eyeball adjustment function can form 'accommodative spasm' or pseudo myopia. Continued development can produce longitudinal eye axis elongation and induce 'true myopia' or axial myopia. The external luminosity of the progressive lens can be artificially added to the progressive luminosity. The upper is used for looking far, and the below is used for looking near, which makes the eyeball relax and over-adjust. The ever-changing luminosity of the lens replaces the 'accommodative power' that should have been activated, blocking the vicious circle of adjusting the eye axis elongation, making the eye not easy to fatigue, and slowing the development of myopia.



Is it expensive to fix glasses?

Many optician shops can fix a broken pair of frames for less than $50. Some retailers, like LensCrafters, provide glasses with a one-year extended warranty for as low as $35. If you have such a warranty, you can have your glasses repaired for a fraction of the cost. Is it expensive to fix glasses? It depends on the specific situation. World Optic, for example, has led the eyeglass repair industry since 1972. World Optic combines over 90 years of eyeglass repair experience and uses cutting-edge technology to create a complete science of the process of repairing broken glasses and sunglasses from start to finish. We have to see that for every single repair, there is a specific quote for different degrees of repair and for different parts.


What Is Anti Reflective Coating?

Anti reflective coating, also known as AR, anti-glare, no-glare, or glare-free coating, can provide benefits to your vision. Anti reflective coating is added to lenses to reduce glare caused by light hitting the back of the lenses to improve your vision and make your eyeglasses more visually attractive.

Anti reflective coating will eliminate all reflections from the front and back surfaces of your lenses. Hence, more light is able to pass through your lenses which improves your vision. At the same time, fewer distractions are visible and the lenses are hardly noticeable, especially in the dark. So, is anti glare worth it? Most people agree that.



What kind of frames can working women choose?

If you are a heart-shaped face, the selection of the frames is different. Of course, to look relatively stable and mature, you can choose some simple frames, like square frames. You can choose gold or black gold, black silver line. Or the kind of slightly Japanese style of small round one, looking more literary and young. The frame can choose pure titanium, relatively light and quality will be better. The choice of the frame should be carried out according to the different working environments. If you are a teacher or doctor, you should choose low-key, elegant frames. If you're a freelancer who needs to show off your personality, you can pick up trendy frames.


When do you need prism glasses?

If you experience symptoms of headache, dizziness, and nausea, then these symptoms may be caused by a subtle disorder between the eyes. This situation is called Binocular Vision Dysfunction(BVD). Double vision occurs in the situation that light enters the eye at the wrong angle and sends two different images to the brain. Some people have diplopia, where they can see only one image, and flat images are often blurry. Prism glasses can help to change visual deformities. Prism lenses can be helpful to prevent myopia and farsightedness in both eyes. If vision deteriorates in one eye, the eye muscle can use an external corrective prism to prevent blindness. Standard glasses are made of a combination of prisms that can correct the focal length errors and corneal curvature. The prism moves the image up and down or left and right to form an overall view.



Why do nose pads turn green?

Because there are copper accessories in glasses. And the copper and sweat mix for a long time, so it will corrode and rust. The greenness is the mixture of copper salt (copper rust) produced by the copper element in the coating and inorganic salt in sweat and grease dust. The color of copper is green, so is the dirt. If you sweat a lot and the lens bracket is metal, the nasal bracket silica gel is easy to turn green. This is usually due to oxidation caused by the combination of nickel with the natural oils in the skin. Your nose is usually the oily part of your body. The oil in the nose mixes with sweat and then oxidizes the metal. Glass frames are usually made of a kind of copper called Monel. Monel is an easily corroded metal that does not react to many chemicals. It's skin-friendly. The only downside is that it turns green when it rusts.
