Ophthalmology knowledge: will myopia continue to deepen in adulthood!

Abstract: if you are in the state of fatigue for a long time and can not be relieved and adjusted, it is easy to lead to ciliary muscle spasm. The continuous contraction time of ciliary muscle is too long, which makes the eyes in the state of fatigue myopia for a long time, and regulatory myopia, namely pseudomyopia, will occur.

many myopia friends are very concerned: will adult myopia deepen? According to experts, this problem varies from person to person. Generally speaking, with the growth of age and the reduction of long-term eye use time in adulthood, vision will tend to be stable, and the degree of glasses will no longer increase. However, some diseases can also deepen myopia, which is worthy of attention.

visual fatigue

at present, the emergence of more and more people with “visual fatigue” is the manifestation of the change of modern lifestyle. Long time close reading, reading too small words, long computer operation time, etc. will overuse the eye adjustment ability, which can cause visual fatigue symptoms such as eye swelling and pain, dry hair, blurred vision, heavy eyelids, and even headache, orbital pain, and even nausea and vomiting.

and

if they are in the state of fatigue for a long time and can not be relieved and adjusted, it is easy to lead to ciliary muscle spasm. The continuous contraction time of ciliary muscle is too long, which makes the eyes in the state of fatigue myopia for a long time, and regulatory myopia, namely pseudomyopia, will occur. For regulatory myopia, if it is not treated early, it will become true myopia.

pathological myopia

pathological myopia, its diopter exceeds 1000 degrees, up to 3000 degrees. Pathological myopia is a kind of high myopia, which does serious harm to visual function. Pathological myopia is mainly caused by genetic factors. Therefore, although some people are not engaged in the work of close vision, they will still get sick, and can have serious complications such as retinal degeneration, hole, retinal detachment, macular hemorrhage and so on.

diabetes

and

, when the blood glucose level of diabetics increases to a certain extent, the sugar content in the eyeball will also increase, causing the aqueous humor osmotic pressure to decrease in the eyes, and the lens may be in relative “hypertonic” state due to the increase of glucose content, resulting in edema, resulting in increased refractive power and myopia symptoms. When the diabetes is effectively treated and the blood sugar is controlled at a normal level for a period of time, the myopia symptoms will gradually reduce to disappear, and the patients will be able to return to normal vision.

cataracts

myopia friends may also have the phenomenon of increasing myopia when senile cataracts are formed, while friends without myopia do not need to use presbyopia glasses to read because of the occurrence of senile cataracts. The degree of presbyopia is improved, just like rejuvenate. Some people jokingly call this phenomenon “the second spring of vision”. For friends with high myopia, if they find that their glasses suddenly deepen or their old flowers suddenly reduce at the age of 50, it is likely to be a manifestation of cataract and must be prevented as soon as possible.

glaucoma

when talking about glaucoma, many people often “talk about cyanosis”. Because glaucoma is an eye disease that seriously threatens vision and visual function, it is mainly related to the increase of intraocular pressure after the block of “aqueous humor” circulation. If effective treatment measures are not taken, high intraocular pressure will compress the optic nerve, resulting in the gradual atrophy of the optic nerve, and the visual field will be gradually lost or even blind.
