Semiconductor-Based 650nm Class I Laser Eye Protector

Abstract

Eye health is essential to national health and involves all age groups throughout the lifespan. Visual impairment seriously affects people’s physical and mental health and quality of life, increases the burden on families and society, and is a public health and social problem involving people’s well-being. Our method of combining acupuncture and physiotherapy to stimulate acupoints was found to relieve eye muscle fatigue and reduce eye tendon contracture and blood stasis. It also causes bio-stimulation within the tissues and improves local blood circulation. On this basis, using a laser instead of a silver needle was improved to stimulate the acupoints. The laser is low-intensity laser irradiation through the laser beam deep inside the tissue, which can play the proper bio-thermal effect and does not damage the body’s normal biological tissues.
