What is blue block lens? Anti-blue light lenses, also known as blue light blocking lenses, are specially designed eyewear lenses designed to filter or block some of the blue light emitted by digital screens, LED lights, and other artificial light sources. Blue light has a short wavelength and high energy, and exposure to blue light, especially at night, can disrupt the body's natural sleep-wake cycle. Blue light lenses help reduce the potential negative effects of prolonged exposure to blue light, such as digital eye strain, headaches, and sleep disturbances. These lenses come with varying levels of blue light filtering, from nearly clear to darker options. Some blue block lenses also feature anti-reflective coatings to further reduce glare and improve visual comfort during screen use. They are growing in popularity as more people spend a lot of time using digital devices and look for ways to mitigate the potential effects of blue light on their eyes and overall health. Can anyone wear blue light blocking glasses?Yes, anyone can wear blue light blocking glasses, regardless of age or vision. These specialty lenses can benefit anyone who spends a lot of time in front of digital screens or under artificial lighting. Whether you're a student, a professional or just someone who enjoys using electronic devices, blue light blocking glasses can help reduce eye strain and potential disruption to your sleep cycle caused by overexposure to blue light. Many people find they help improve visual comfort during screen time and promote healthier sleep patterns. Always consult an eye care professional to determine which lens option is best for your specific needs and ensure proper fit and vision correction if needed. Is it bad to wear blue light glasses all day?Wearing blue light glasses throughout the day is generally not harmful if used as intended and prescribed. These glasses are designed to filter out some of the blue light emitted by digital screens, artificial lighting and other sources, which can help reduce eye strain and potentially minimize disruption to sleep-wake cycles. However, it is important to ensure that the lenses are of high quality and prescribed by an eye care professional. Wearing glasses that are not designed for all-day use or that are incorrectly prescribed can cause discomfort or even worsen vision problems. Be sure to follow the advice and instructions provided by your eye care professional to ensure you are using blue light glasses safely and effectively. If you're concerned about wearing blue light glasses all day, it's best to talk to an eye care professional. Do blue blocker glasses really work?Anti-blue light glasses, also known as blue light glasses, are designed to filter out some of the blue light emitted by screens, artificial lighting, and other light sources. Potential benefits of wearing blue light-blocking glasses include reducing eye fatigue, minimizing disruption to sleep-wake cycles, and improving overall visual comfort, especially when using digital devices for extended periods of time. While personal experiences may vary, many people report feeling more comfortable and experiencing less eye strain when using blue light blocking glasses. However, scientific research on the effectiveness of blue light blocking glasses has produced mixed results. Some studies suggest that wearing these glasses may not significantly affect sleep quality or eye strain, while other studies support their potential benefits. Ultimately, whether blue light glasses are right for an individual may depend on a variety of factors, including their specific use of digital devices, the quality of the glasses, and their overall eye health. If you are considering wearing blue light blocking glasses, be sure to consult with an eye care professional to determine the best method for your specific needs.

According to authoritative statistics: the rate of traffic accidents at night is 1.5 times higher than during the day, and more than 60% of major traffic accidents occur at night! And 30-40% of accidents at night are caused by misuse of high beams! Therefore, high beams are the first killer of eyes and night driving safety! In everyday driving, in addition to high beams at night, the glare reflected off the tarmac can be visually fatiguing, and one of the factors contributing to these visual disturbances is - glare. What is glare? Due to the inappropriate brightness distribution or brightness range, or the existence of extreme brightness contrast, causing uncomfortable visual feelings or reducing the visual phenomenon of observation details, collectively referred to as glare. When we are exposed to glare, the human eye will feel stimulated and tense, and working under such conditions for a long time will produce feelings of boredom, impatience and fatigue, which will have a great impact on life. Why is there glare? The most common glare in daily life is reflected light from sunlight on various surfaces. The light wave of sunlight has wave-particle duality, that is, the vibration direction of sunlight as an electromagnetic wave is perpendicular to the propagation direction. The vibration of the electromagnetic wave will be like a rope jitter, and it can be biased in all directions, forming a variety of polarization. light1 When light strikes a smooth surface, it is reflected, and the vibration of the reflected light in the same direction as the reflecting surface is intensified. For example, when sunlight strikes a wet pavement, the light is reflected and polarized by the smooth surface, and this reflected light creates an uncomfortable dazzling effect (glare) for the human eye. This glare can cause some problems: White reflections cover the object's color, making it difficult to see the object as it is. High-brightness reflections can cause eye discomfort and visual fatigue. How do I stay out of the glare? Choose our anti-glare lens-The best for outdoor and driving people 1. Aspheric design reduces the peripheral aberration of the lens, compared with ordinary spherical lenses, the vision is more realistic and lifelike, especially for high number of wearers, the imaging effect will be more obvious; at the same time, the lens is lighter, thinner and flatter. Aspheric design1 2. Uses a dual-color film layer to filter UV rays, giving your eyes an extra layer of protection. 3.

The foreign body sensation after wearing the lens did not improve after removing the protein;3. In the morning after wearing the lens, the eyes often have more secretions or even inflammation without any reason;4. In the case of wearing glasses normally, the naked eye vision in the daytime for several days is obviously decreased 3, How to deal with wear and tearRegular review is a good way to avoid serious wear and tear, when it is not serious, can be polished to restore the condition of the lens.However, there is one caveat! Polishing grinding is bound to affect the design of the lens, so wear often probability has influence on the wearing effect after (such as shaping effect, comfortable degree and vision during the day, etc.), so it is a necessity to practice, were it not for the lens and cornea of the fit status also needs to be modified, otherwise, and not as a universal method of repair! And when the wear is very serious, the above 4 kinds of conditions, often even polishing and polishing can not save the lens, can only stop wearing change processing, so be sure to wear the mirror review on time! 4, How to prevent itThe prevention method is mainly in the cleaning step, keep hands soft and clean, nails short and smooth, finger abdomen and palm without dead skin and calluses.

If the convex side is up, gently suck directly with the suction rod.
