1. Can myopia and presbyopia offset each other?
and
some people say that myopia will not cause presbyopia, and myopia and presbyopia will offset each other! This can make many myopic people happy. When we are old, we will not be presbyopia. Then it will be your turn for people who are not short-sighted to wear reading glasses. Is that really the case?
truth
presbyopia can occur in myopia, hyperopia and astigmatism. But when people with myopia look close, they can relatively reduce the degree of presbyopic convex lens or just take off their myopia glasses. The problem of seeing close comes earlier for those who are far sighted or face up to their eyes. Many of them may have to wear reading glasses or binoculars after the age of 40.
2. Will wearing glasses for too long really deform your eyes?
anecdotal rumors: do not wear glasses for a long time, which will deform the glasses! The glasses family really can’t afford to hurt!
truth
wearing glasses is because of ametropia such as myopia or hyperopia. Refractive errors such as myopia or hyperopia can lead to eye deformation. If the same patient does not wear glasses, his eyes are also deformed.
3. Presbyopia and hyperopia are “twins”?
presbyopia and hyperopia are not the same concept, nor are they “twins”. Never confuse presbyopia with hyperopia!
truth
presbyopia is one of the types of ametropia. Everyone will suffer from presbyopia at a certain age (generally over 40). Hyperopia is due to the short axis of the eye. The parallel light enters the eye and falls on the retina through the refraction aggregation point, so that the external image cannot be clearly imaged on the retina. At this time, the eye often enhances the refractive power through adjustment, so that the parallel incoming light gathers on the retina to form a clear image.
4. Will night light color affect mood?
it is said that the color of night lights can not be ignored, which may affect your mood. Scientists found that blue light had the greatest negative impact on mood, followed by white light. Compared with blue light or white light, hamsters exposed to red light at night had the lightest depressive symptoms and changes in corresponding brain regions.
truth
restrict the lighting of computers, televisions and electronic devices used at night. If you must use light, you need to mind the color of the light. If you need a night light in your bathroom or bedroom, it’s best to use red light instead of 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 is easy to deepen.
truth
after myopia, you need to wear glasses, because the purpose of wearing glasses is not only to correct refraction and clear vision, but also to prevent the imbalance of eye adjustment and collection function.
6. look out! Can myopia surgery cause blindness?
myopia surgery is a conspiracy in the medical community. Myopia surgery will be blind, myopia surgery will cause cataract, and even “I don’t know about myopia surgery, but I just want to say it’s bad…” the truth of
myopia surgery generally improves vision by changing the cornea without damaging the fundus and retina, In other words, myopia surgery does not exist to make you blind.
7. Does wearing sunglasses outdoors affect children’s visual development?
and
babies also need cool sunglasses. Parents can rest assured to wear sunglasses for their children in summer. Wearing sunglasses purchased through formal channels will not affect their children’s visual development!
truth
infants have higher lens transparency than adults, which means that ultraviolet rays penetrate more. With age, the color of the lens gradually turns yellow, and the ultraviolet light reaching the retina gradually decreases. The lens actually plays the role of intraocular sunglasses. If you don’t wear sunglasses for your child, the child’s lens will be forced to absorb more ultraviolet rays.
8. “Correct” myopia is to cure myopia?
many people think that “correcting” myopia is to cure myopia? Myopia, hurry to “correct” it, and the problem will be solved. Is that true?
truth
is limited to people’s understanding and the current situation of basic and clinical research. At present, the treatment of ametropia is still limited to correction, there is no really effective treatment, and it is impossible to fundamentally cure myopia and hyperopia.
9. After amblyopia is cured, you can take off your glassesAre you?
in the later stage of children’s amblyopia treatment, many parents often ask the same question with great expectation – “can my child remove his glasses after amblyopia is cured?” Some parents even take off their glasses after being told that their children’s amblyopia has been cured. Is this really possible?
truth
whether glasses can be removed does not depend on anyone’s wishes or preferences, but on whether they can meet the healthy visual standards after removing glasses. The goal of amblyopia treatment is to further establish and restore binocular visual function on the basis of improving amblyopia visual acuity, rather than “take off the glasses”.
10. Is reading in dim light harmful to your eyes?
and
are so dark that reading is bad for your eyes. Turn on the light quickly and be careful of myopia. You can use your eyes to ensure sufficient light. Reading in dim light is not good for your eyes. Is this true?
truth
for middle-aged and elderly patients with angle closure glaucoma or susceptible people (short people with family history, short limbs and short fingers), the lights must be turned on when reading, reading newspapers and watching TV at night to ensure that the indoor light is bright. Because the pupil will expand under the dim light, it is easy to induce the attack of angle closure glaucoma. The risk of angle closure glaucoma in myopic people is very small. It’s OK to look at the mobile phone before going to bed. The only disadvantage is that it will lead to eye fatigue and dry eye.
