【英语单词high myopia的用法讲解】

High myopia is an eye disorder in which the eyeball is longer than normal. It is a kind of refractive error of the eye, which means that images focusing onto the retina are out of focus. People with high myopia have difficulty seeing far away objects clearly, even when corrective lenses are worn. It can also be accompanied by other eye disorders, such as retinal detachment, glaucoma and cataracts, which further impair a person’s vision.

High myopia is typically diagnosed in childhood and can worsen over time, especially if left untreated. The exact cause of high myopia is not known, although it is generally believed to be inherited. It can also be caused by environmental factors, such as extended exposure to computers, cell phones and other electronic devices.

Treatment for high myopia typically includes vision correction through eyeglasses, contact lenses or surgery. Surgery is usually the last resort and is used to correct more severe cases. Glasses or contact lenses are the most common solution. People with high myopia may also be prescribed bifocals or trifocals to improve their vision while also accommodating their need for magnification.

High myopia can be a debilitating condition if left untreated. It can limit a person’s ability to do everyday tasks, hinder their academic performance and lead to other serious eye disorders. With the right treatment, however, many people with high myopia have no significant visual impairment. Regular eye exams are important for people with high myopia to ensure that their vision is monitored and their prescriptions are up to date.
