Anti-blue light glasses cannot prevent myopia, and there is currently no scientific basis to suggest that 'anti-blue light glasses can prevent myopia'. Blue light is divided into harmful blue light (with wavelengths ranging from 400nm to 450nm) and beneficial blue light (with wavelengths ranging from 450nm to 500nm). Harmful blue light is ubiquitous in daily life, and the main prevention is these harmful blue lights with wavelengths ranging from 400nm to 450nm!

Both high and low blue light barrier rates can cause discomfort to the eyes. The recommended barrier rate for a pair of anti-blue light glasses is between 60% and 70%. If the barrier rate is too high and the lenses are dark, it will affect the color distortion rate and cause discomfort to the eyes. A low blue light barrier rate results in a poor anti-blue light effect and a less obvious protective effect. Generally, legitimate merchants will indicate the barrier rate of their products.
