Blue light blocking glasses lenses and common glasses lenses have different colors.
The real blue-light-blocking glasses should be yellow. Based on the primary principles of optics, the light reflected from the lens is the light that resists the same color as it. As the name indicates, blue light is to prevent the reflection of blue light. Remove blue light, and all the red, yellow, blue, and green in visible light is yellow.
Aluminum Night Driving Glasses
These night vision glasses feature advanced HD technology. The aluminum frame is lightweight, allowing you to comfortably wear your driving glasses and reduce glare for safe driving. Because the lenses are yellow, these glasses act as night vision goggles to reduce glare, reflections, and their negative effects, while improving and brightening the visual area. Polarized lenses have a special anti-reflective coating that eliminates intense reflected light and reduces glare and scattered reflections. They can double as day and night glasses, improving clarity around the clock.
In terms of positioning, it should conform to students' purchasing behavior, that is, the middle and low-grade products are mainly used, and the appearance requirements are stylish and novel. In addition, you can be properly supplemented with a small number of high-end products, because your market is not only the school but many residents around.
How To Use Contact Lens Correctly?
A periodic review is necessary. In the process of wearing contact lenses, the eyes may change due to the existence of contact lenses. At the same time, in the process of wearing contact lenses, the lens may be polluted, damaged, and have other changes. This is to check regularly to prevent damage to the eyes. Usually, the recommended review period is one week, one month, three months, half a year, and once every half a year after wearing it.
Ralph Lauren has a strong American flavor. It has created a world of high-quality fashion sales and continues to promote the prestige of the designer Ralph Lauren and the brand Ralph Lauren. All the details are structured on a value that is timeless. The glasses are selected by pressing and grinding metal materials to emphasize the three-dimensional changes on the line of the temples. The simple and introverted design style is more conducive to collocation clothing, a fusion of plate massiness and metal texture. They use high elastic material, super-tough without deformation. Both clothing and furniture cater to customers' yearning for a perfect life in the upper class.
BLUPOND night driving glasses
TAC Semi-polarized Blue light goggles are designed to change your perspective to yellow with computer blue light polarization. Anti-glare high-definition vision blue-blocking glasses protect eyes from blue light and reduce the contrast of bright blue/white glare and flash. The anti-glare night glasses limit distortion. In addition to polarized driving glasses, you can receive a night vision glasses accessory set, with the EVA glasses hard case, screwdriver, sunglasses bag, microfiber cleaning cloth, glasses clip, and night driving glasses gift box.
Testing of aspheric lens
The optical axis of the optical center just overlaps with the visual axis of the eye, which is the most ideal state. Because the light from the edge cannot form a focus on the optical axis, when the optical axis does not overlap with the visual axis (the difference is greater than 2mm), such unclear and scattered imaging results will occur. When choosing frames and aspheric lenses, you need to ensure that they fit correctly, to achieve the best visual and decorative effects. Simply put, due to the special design of the lens, we found through a calculation that the optical center should move down 1mm higher than the pupil for every 2° increase in front inclination angle. Otherwise, the wrong pupil height will cause the lens to look like astigmatism, and cause discomfort. For glasses with aspheric lenses, there must be an inclination angle after wearing. The specific angle varies from person to person.
