Who is suitable to wear progressive lenses
Progressive multifocal glasses are suitable for people with presbyopia or visual fatigue, especially teachers, physicians, musicians, computer operators, etc. They not only need to see far and near objects, but also most of the time, need to see objects at intermediate distances such as blackboards, piano scores, and computer screens. A pair of scientifically customized progressive multifocal glasses can simultaneously meet the needs of distance use, near use, and various distances in between. Some special young myopia patients wearing progressive multifocal glasses can also be used to correct the refractive power and effectively relieve eye fatigue.
How to Choose Glasses for Long Face?
Bold shapes and eyeglasses with decorative details are also a smart choice since they help draw attention to your eyes and can add width to your face. Be sure to avoid narrow or rectangular shapes, which can make your face appear longer.
Square glasses: if you have a long face, you can try square glasses whose sharper corners can help to balance out the length of your face and complement your narrow features. Choose frames that are slightly wider than your cheekbones to make your face appear broader.
Two-toned glasses: if you have a long face shape, the two-toned glasses would be a good choice. The color-top frames create an optical illusion that draws focus upward toward your eyes rather than to the length of your face.
Figure out the categories of driving glasses
Driving glasses are usually divided into daily and night glasses. Daily use refers to the glasses with anti-glare function and darker colors like gray, brown and gray-green, and other colors. Daily lens transmittance is over 8%. Night type usually refers to the glasses that can prevent glare from headlights of opposite vehicles and increase brightness at the same time. That is, it can prevent lights and not block the road, and can brighten and increase the visual scope. Night lenses have a transmittance of more than 75%.
Why should children be more vigilant about harmful blue lights?
The amount of light transmitted to the retina through media such as the cornea, lens, and vitreous is age-related. Blue light poses the greatest risk and damage to the eyes during adolescence. As our eyes' refractive media naturally yellows, more blue light is absorbed, preventing it from reaching the retina. The lens transmittance of children under the age of 10 is more than six times higher than that of adults. It is important to prevent the damage of blue light to children's visual health.
Advantages of aspheric lenses
In reality, aspheric lenses were originally born to improve the marginalized optical properties of spherical lenses. The aspheric lens with special coating treatment has perfect visual performance, with a clearer, more comfortable visual effect. You can hardly feel the presence of aspheric lenses when you put them on. So you can enjoy the ease brought by aspheric lenses. They are more natural and more realistic, having less visual distortion. The aspheric lens can be designed with a flatter base arc, which not only makes the appearance beautiful but reduces the peripheral magnification so that when others look at the eyes of the people who wear glasses, the size will not change much.
Glasses donation is also a form of recycling.

It is mainly aimed at orphans, left-behind children, single-parent families, and adolescents with mental retardation in poor mountainous areas. It lets the children who can not afford glasses really feel the care and warmth brought by people from all walks of life. Encourage them to take good care of their eyesight, study happily and grow healthily. And it can enhance the self-health care consciousness of young students.
