LED vision care lamp for relieving ciliary muscle fatigue by virtue of stroboflash

Abstract

The invention provides an LED vision care lamp for relieving ciliary muscle fatigue by virtue of stroboflash to relieve the ciliary muscle fatigue. The LED vision care lamp mainly comprises a base; a lampshade is movably connected to the base; a lighting power light source and a control circuit used for regulating and controlling the lighting power light source are arranged in the lampshade; the LED vision care lamp further comprises a flashing device for emitting multiple flashing to a background environment; the control circuit is connected with the flashing device to control the flashing device; a brightness regulating circuit is further arranged between the flashing device and the control circuit; the brightness regulating circuit is used for amplifying the current or the voltage of the flashing device. When eyes are stimulated by instantaneous flashing, due to no visual object of a fixed focus before the eyes, the optic nerve unconsciously forms distant-view illusion, the ciliary muscle and the crystalline lens naturally stretch and relax, and the ciliary muscle fatigue or spasm due to being frozen in a state for a long time and the resulting descending of the regulation function of the ciliary muscle are avoided; as a result, the eye fatigue is effectively relieved and the purpose of vision care is achieved.

Description

technical field [0001] The invention relates to an eye-protecting and health-care lamp, in particular to an LED vision-care lamp for effectively relieving eyelash muscle fatigue through stroboscopic flashing. Background technique [0002] Myopia refers to the fact that the external light, after being refracted by the refractive system of the eyeball (mainly the cornea and lens), does not focus precisely on the retina, but falls in front of the retina. Although there are many factors that cause myopia, the myopia caused by the eye's ciliary muscle being in a state of fatigue for a long time is particularly common. This is because the lens is thickened by contraction of the eye ciliary muscles in order to make the vision clear when looking at close up. If this happens for a long time, the eye ciliary muscles are too tense and easy to fatigue, which in turn leads to a decline in the ability to adjust and affects vision.
