1.Can myopia and presbyopia cancel each other out? Some people say that myopia does not cause presbyopia, myopia and presbyopia will cancel each other out! This can make many nearsighted people happy. When we are old, we will not have presbyopia, and then it will be your turn to wear presbyopic glasses for those who are not nearsighted. The truth is that both myopia, farsightedness and astigmatism will have presbyopia. It’s just that people who are nearsighted can relatively reduce the number of convex lenses in their presbyopes or simply remove the glasses they wear for nearsightedness. The farsighted or orthoptically sighted people will have problems looking closer earlier, and many of them may have to wear presbyopia or bifocals after the age of 40. 2, wear glasses for too long will really make the eyes deformed? Anecdotal evidence: don’t wear glasses for a long time, this will make them deformed! The glasses family can not really hurt ah! The truth is that wearing glasses because of myopia or farsightedness and other refractive errors. Myopia or farsightedness and other refractive disorders can lead to eye deformation, if the same patient does not wear glasses, then his eyes are also deformed. 3. Are presbyopia and hyperopia “twins”? Presbyopia and hyperopia are not the same concept, nor are they “twins”. Don’t confuse presbyopia with hyperopia! The truth is that presbyopia is one type of refractive error. Everyone who reaches a certain age (generally over 40 years old) will suffer from presbyopia more or less severely. Farsightedness is due to the short axis of the eye, parallel light into the eye, after refraction gathering point on the retina, so that the external image can not be clearly imaged on the retina, then the eye is often adjusted to strengthen the refractive power, so that parallel light gathered on the retina to form a clear image. 4.Does the color of the night light affect the mood? It is said that the color of the night light can not be ignored, it may affect your mood. Scientists have found that blue light has the greatest negative impact on mood, followed closely by white light. Hamsters exposed to red lighting at night had the mildest depression-like symptoms and changes in corresponding areas of the brain compared to blue or white lighting. Truth Limit the lighting of computers, televisions and electronic devices used at night. If you must use lights, you need to be mindful of the color of the lights. If you need a night light in your bathroom or bedroom, it is better to have red light rather than white. 5, children with mild myopia do not need to wear glasses? Some parents believe that children with mild myopia do not need to wear glasses and can slowly adjust to normal vision. After wearing glasses, the degree of myopia will easily deepen. Truth With myopia, it is necessary to wear glasses, because the purpose of wearing glasses is not only to correct refraction and clear vision, but also to prevent the loss of balance in the adjustment and collection function of the eyes. 7. Wearing sunglasses outdoors does not affect your child’s vision development? Babies also need cool sunglasses, parents please feel free to give their children to wear sunglasses in the summer, wear through the regular channels to buy sunglasses will not affect the development of children’s vision! Truth: The lens of infants is more transparent than that of adults, which means more UV light penetrates. The lens gradually becomes more yellow as they get older, and the amount of UV light reaching the retina only gradually decreases. The lens actually plays the role of a sunglass inside the eye, and if you don’t give your child sunglasses, the child’s lens will be forced to absorb more UV light. 8, “correct” myopia, is to cure myopia? Many people think that “correcting” myopia is to cure myopia? Myopia, hurry up and “correct” the problem will be solved. Is this really true? The truth is that due to people’s awareness and the current state of basic and clinical research, the treatment of refractive errors is still limited to correction, there is no real effective treatment, and it is impossible to fundamentally cure myopia and hyperopia. 9. Can I take off my glasses once my amblyopia is cured? In the later stages of amblyopia treatment for children, many parents often ask the same question with great expectation – “Can my child take off his glasses once he is cured of amblyopia?” Some parents even remove their glasses on their own after being told that their child’s amblyopia has been cured. Is this really possible? Truth Whether or not glasses can be removed does not depend on anyone’s desire or preference, but rather on whether or not healthy vision standards can be achieved with the glasses removed. The goal of amblyopia treatment is to build and restore binocular vision based on improving the vision of the amblyopic eye, not to “take off the glasses”. 10. Is reading in dim light harmful to the eyes? So dark, reading is not good for the eyes, hurry to turn on the lights, careful eyes myopia. With the eyes can ensure adequate light, dim light reading is bad for the eyes, is this true? Truth For middle-aged and elderly patients with closed-angle glaucoma or susceptible people (short people with family history, short limbs, short fingers), reading newspapers and watching TV at night must be turned on to ensure that the room is brightly lit. Because the pupil will dilate in dim light, it is easy to trigger the onset of closed-angle glaucoma. The risk of closed-angle glaucoma in near-sighted people is very small, and it’s okay to look at the phone before bed, but the only drawback is that it can lead to eye strain and dry eyes.
