Blue light is not the unique light emitted by electronic products, but the visible light that exists in natural light, usually with a wavelength of about 400-500nm. The blue light in the entire waveband can be subdivided into two parts. One part will cause optical damage to the retina of the eye and accelerate the oxidative senescence of cells in the macular area of the retina. Usually, the wavelength of this part of blue light is between 415-450nm, and its damage to the eyes is gradually accumulated and formed.

Consider possible uncertainties after the lens is installed.

Usually, in-store frames are made of plastic samples rather than actual lenses, so they weigh slightly less. However, it is necessary to consider the approximate weight of the lens in advance according to its own degree when trying it on, in case the weight is not suitable for real wearing. If the pupil distance is too small, it is not suitable to wear a wider frame. The machinist should strictly follow the left and right pupil distance instead of taking the average, otherwise, there will be pupil distance error in the left and right eyes, which will cause discomfort in wearing.
