Progressive Lens

Standard progressive lenses are multifocal lenses with three observation areas, farsightedness, intermediate vision, and nearsightedness. Unlike bifocals, there are no visible lines between each viewing area. They have a seamless, invisible design, where the optical power changes 'gradually' throughout the lens. Many people confuse 'bifocal' or 'trifocal' with 'progressive' but remember that bifocals and trifocals have visible lines in the lens, while progressive lenses do not. Because progressive lenses have no lines in the lens, they are more popular multifocal lenses than bifocal lenses.

The main observation area of the progressive lens is a far distance, the smaller area at the bottom of the lens is used for myopia, and the middle area in the middle is smaller. Standard progressive glasses are very suitable for general purpose glasses, focusing on hyperopia activities (such as driving and walking) and sufficient area in the lenses for nearsighted activities (such as reading and computer use). The left and right sides or 'convex corners' of the lens are deliberately blurred to achieve an invisible design. The clearest line of sight in the gradual process is from the center to the top of the lens.


What are prism glasses?

What is a prism? A prism is a solid object with a cross-section along its entire length. If you cut across something, you'll come across a section that's been cut, and that's a cross-section. The upward section is a prism. If you have double vision, you can add a prism prescription to the lens to form prism glasses. It can help keep your eyes focused and greatly improve your vision. In most glasses, prisms are used primarily to change double vision and are useful for image correction. They can aid in position correction.



Disadvantages of carbon fiber glasses frames

One disadvantage of carbon fiber materials is that they are more brittle, so spectacle frames will break after being bent to a certain extent, which is not as tough as metal. Carbon fiber materials are more complex to process, so carbon fiber spectacle frames are better than conventional spectacle frames. Also, it is much more expensive. If there are too cheap ones, you need to carefully consider its authenticity. In addition, the carbon fiber spectacle frames are difficult to repair once damaged.

At present, carbon fiber material has been used by many high-end eyewear brands, which shows that it has a very good effect on the improvement of product quality. The popularization of carbon fiber as an excellent material in daily necessities has a positive effect on the improvement of people's quality of life.

Is it necessary to repair the glasses that are badly damaged?

If your glasses are badly damaged, think about getting a new pair. Maintenance is maintenance, not a replacement, so there are some traces of maintenance. The repair cost is far more than or can buy a new pair of glasses, so there is no need to repair them. For the kind of alloy that's used for cheap glasses and the kind of alloy that's used for high-end glasses, the texture of the welding is so different. There are differences in intensity. In order to make the cheap glasses strong after welding, it will definitely increase the welding marks (solder repair, etc.), so the marks will be obvious.
