Are Polarized Sunglasses Worth It?

What kind of glasses can people with round faces choose?

Always thought, like what has been said on the Internet, if you wear black frame glasses with large lenses, they can make you look small on the face. This is a mistake, because the black frames are too obvious, creating the wrong area on your face where the glasses are too small.

And for this kind of rimless glasses, because the bottom part is transparent, they will not destroy the partition, and you will feel the face is pretty sharp. For a man with a round face, the appropriate choice is a flat or pear-shaped frame. For a woman with a round face, in principle, she should avoid choosing any very obvious characteristics of the frame, and should not choose a too round or straight-line frame. Round faces are suitable for slender or square frames or pear-shaped frames. The human face of a round face is shorter, so, they had better match the slender glasses frame that takes curve slightly to reconcile the whole feeling. The square glasses or the frame with angle, are helpful for modifying the facial ministry line, highlighting the longitudinal line.


What is blue light?

To prevent blue light, we must first understand what blue light is. The visible light with a wavelength range of 400-500 nanometers is called blue light. The light sources used in daily LED lighting and display products, including mobile phones, flat panels, and TVs, are mostly LED light sources excited by blue light. However, not all blue light is harmful to the human body. The human eye has an extremely low tolerance to blue light radiation in the 400-440 nanometer range. When the light intensity enters this threshold, photochemical damage is likely to occur. However, blue light radiation in the range of 459-490 nanometers is essential for regulating the human body's circadian rhythm and can affect the secretion of human melatonin, which in turn has an impact on the body's biological clock, alertness, and mood.

Scientifically effective anti-blue light lenses must not only block harmful blue light but also cannot filter beneficial blue light. Most of the ineffective anti-blue light products on the market currently have two types of problems. One is that there is almost no protective effect on the blue light in the vulnerable zone of the human eye. The other is excessive protection, shielding the blue light spectrum in the beneficial band so that the blue light that is beneficial for physiological adjustment cannot enter the human eye. At the same time, the color of the lens is yellow, which is prone to color shift, aggravating visual fatigue, and even inducing the risk of myopia.
