Alternating hot and cold compresses on the eyes can be helpful in relieving fatigue and other discomforts of myopia, and can only relieve some of the discomfort, but it does not help with the loss of distance vision, as true myopia is irreversible. Myopia is a type of refractive error, meaning that parallel light rays focus behind the retina causing blurred vision. When swelling and pain occur in myopic eyes, appropriate cold compresses can shrink the blood vessels and pores in the eyes, which can reduce swelling and stop pain. Secondly, myopia often occurs vision fatigue, appropriate and timely hot compresses can improve blood circulation, relieve eye soreness, foreign body sensation and other discomforts. However, myopia is mainly manifested as a loss of distance vision, so, hot and cold compresses have no therapeutic effect on myopia, and need to wear framed glasses or corneal contact lenses for correction, or through surgical correction. It is recommended that myopic people develop good eye habits, timely and scientific glasses to correct vision and prevent deterioration.
