Contact lenses up to 40 years old
Primary and middle school students are in a period of vigorous growth and development, and the visual axis of the eyeball has not yet been shaped. If contact lenses are worn prematurely, corneal hypoxia and physiological metabolic disorders are likely to occur. If the labyrinth of the lens does not match the cornea, it can also cause corneal abrasion, which can lead to corneal ulceration or perforation. Therefore, unless there is a special need, it is best for primary and secondary school students to wear spectacles. After the age of 40, there will be obvious degenerative changes in the eye tissue, and the ability of the eyeball to withstand hypoxia will decrease. If a lens is worn on the surface of the eyeball, it will cause hypoxia of the eyeball, thereby inducing corneal infection. Complications such as ulcers. Therefore, people over the age of 40 are best not to wear contact lenses. Young people wear contact lenses. Once they feel foreign body sensation, dryness, congestion, abnormal secretions, burning pain, etc., they should stop wearing them immediately and go to the hospital. Other situations in which contact lenses are not suitable include eyelids, conjunctiva, corneal inflammation, blisters, and dacryocystitis.
