Progressive multifocal glasses are gradual lenses, which gradually increase from flat light or low degree to high degree to realize the far, middle and near space vision function under the condition of central gaze. As the added value continuously increases gradually in the gradient area, the wearer can obtain continuous clear vision from far point to near point through lenses at appropriate eye positions. This design conforms to physiological optics and has good adaptability. Both sides of the lens are astigmatic obstacle areas. You need to turn your head and eyes to see the objects on both sides clearly. If you squint at these areas, your vision may be distorted and you will feel uncomfortable. Because these areas are mixed together, there will be obvious but expected blurring when viewing the lens edge. It is not suitable for driving. Magnification Choice The top of the lens can clearly see the distance. The middle of the lens can be used to watch TV and computer. The bottom of the lens can be used for reading. You can adjust your vision by moving your eyes up and down as needed. What is Blu ray? The blue light wavelength in the visible spectrum is very short (380-500 nm), and the energy is the highest in all visible light. It can be found in the sun. It is a necessary condition to maintain our vitality and sobriety, and it can also regulate our circadian rhythm. However, problems arise when a large amount of blue light comes from artificial light sources. In addition, the popularity of electronic products with screens and energy-saving lighting increases the possibility of exposure to blue wavelengths The cornea and lens of the naked eye cannot block this harmful light. This is why blue tinting glasses become very important. When facing the digital screen, reduce eye fatigue and sensitivity to light. This is the right choice for office workers or anyone who has to watch the screen all day. Protect your eyes from daily life, minimize headaches caused by blue light, and enjoy digital time\u003c\/p\u003e\u003cp\u003eFrom the brand HIYANJN progressive \/ bifocal reading glasses for women \/ men Fashion reading glasses The style of glasses is easy to match, retro and simple.
