Blue light is harmful to eyes mainly in myopia, cataract, and macular disease.

1, harmful band of blue light energy can penetrate the lens directly to the retina, causing retinal pigment epithelial cell atrophy and even death, cell death will lead to visual decline, and this damage is irreversible!

2. Due to the short wavelength of blue light, the focus of blue light in the glasses will be before the retina. In order to see clearly, the eyeball must be in a state of tension.

3. Blue light can inhibit the secretion of melatonin, which is an important hormone affecting sleep. This is also the reason why playing mobile phone or computer before bed can cause poor sleep quality or insomnia.
