Separating facts from prejudice is crucial at all times. Let's address some common misconceptions about vision.

Before dismissing them, it's important to keep two things in mind: first, protecting your eyesight is vital; and second, some of these beliefs, though not directly related to vision, may impact other aspects of your health.

Myth 1: Don't wear glasses if you're nearsighted; you can't take them off!

Explanation: Glasses serve the sole purpose of making your eyes see clearly. Scientific research and clinical experience have shown that wearing glasses does not harm our eyes. In fact, without glasses, myopia may progress faster.

Myth 2: There are many ways to treat myopia; treatment is good!

Explanation: Myopia cannot be cured. If you come across advertisements claiming otherwise, do not believe them."

Myth 3: Myopia is not high; paying attention to eye habits will make it better!

Explanation: Myopia is irreversible, especially in the physical development of children. Once myopia sets in, without specific intervention methods, it not only won't decrease but will likely continue to increase.

Myth 4: Wearing eyeglasses will make your eyes more convex.

Explanation: High myopia may result in a slight convexity, but it's not significant—only about 0.94 millimeters more convex than normal. It's mostly a visual illusion, as the eye seen through a concave lens appears normal-sized.

Myth 5: Myopia glasses are always worn if they are not broken.

Explanation: Lenses need replacement with any change in prescription. Over time, glasses develop scratches and age, affecting vision quality and leading to visual fatigue.

Myth 6: Myopia and astigmatism.

Explanation: Most astigmatism is related to the cornea's shape. For those without astigmatism, the cornea resembles a basketball; for those with astigmatism, it's more like a rugby ball. Astigmatism is generally innate and does not continue to increase.

Myth 7: Don't give so much prescription; just make up for it!

Explanation: Prescription strength depends on the wearer's eye function, comfort, and correction needs. Arbitrary increases or decreases can lead to faster myopia progression, especially in children.

Myth 8: Glasses can be worn when looking at a distance but not when looking at a near distance.

Explanation: While eyes can be lazy without glasses for myopia, long-term lazy eye function will decline. It's recommended to wear glasses for both near and far vision, except under special circumstances.

Myth 9: Contact lenses cannot be worn; they will hurt the eyes.

Explanation: Contact lenses are a tool for myopia correction. Handling them incorrectly may damage the cornea. However, following the doctor's instructions ensures their safe use. The doctor must screen for any poor fit or other conditions before fitting.

Myth 10: Dilated pupils are harmful to the eyes.

Explanation: Pupil dilation may cause photophobia and vision difficulties, which are normal phenomena. Parents need not worry; simply avoid bright light exposure after dilation and refrain from close-range eye use. The normal dosage of dilated pupil medicine seldom produces side effects, but consult a doctor if any symptoms arise.
