Myopia is the most common refractive error today. To treat myopia, most patients will go to eye hospitals. People with myopia have difficulty seeing distant objects but can clearly see nearby objects. For example, you may not recognize a highway sign until you are only a few meters away. The condition can progress gradually or rapidly, often worsening in childhood and adolescence.
Causes of myopia include:
The axis of the eyeball in the eye is longer than normal Often looking too close The lens and cornea have too high focusing power Myopia includes some of the following types:
Simple myopia
This is the most common condition, usually occurring in children between the ages of 10-18. For people with simple myopia, myopia will be less than 6 diopters and is accompanied by astigmatism.
Eyes often have to work at close distances, causing the lens to swell and not collapse again, which is the cause of myopia. The disease is often caused by genetics and working mode. The disease will develop for a while and stop to a certain extent.
Secondary myopia
Here are some causes of secondary myopia, including:
Vitreous fibrosis Some prescription drugs cause side effects High blood sugar and others

Night myopia
A condition where vision is reduced at night or when the light is low, but the eye's vision is still normal during the day is called night myopia. For people with myopia at night, the pupil will adjust to dilate to capture more light, resulting in a distorted image when reaching the eye.
False myopia
False myopia is a condition in which the eyes increase accommodation, causing the ciliary bodies - in charge of adjusting the eye's ability to adjust - to stiffen, causing temporary impairment of distance vision.
After a period of rest, vision will recover. The signs of false myopia are the same as those of normal myopia.
Degenerative myopia
This is the most severe myopia condition, patients often have myopia of more than 6 diopters accompanied by degeneration of the posterior part of the eyeball. The eyeball's axis is continuously lengthened, causing the degree of myopia to continuously increase, the degenerative myopia condition will become more and more severe.
If people with degenerative myopia are not treated in time, it will cause dangerous diseases such as retinal degeneration, retinal detachment, glaucoma... seriously affecting the health of the eyes.
The disease is quite rare, usually develops at an early age, so it is necessary to regularly take the child to a reputable eye hospital.

Myopia usually occurs in people between the ages of 8 and 12. However, the disease can affect all subjects, all ages. The disease can be controlled by reducing risk factors.
Some factors increase the risk of myopia, such as:
Genetics: children whose parents are nearsighted often have a higher risk of developing the disease. Reading, watching TV, looking at the computer a lot Due to environmental conditions, such as spending less time playing outside

While eyeglasses, contact lenses, eye drops and refractive surgery can control the effects of nearsightedness and allow patients to see better at long distances. The aim of these treatments is to treat the symptoms of the condition, not to address the cause.
When the axis of the eyeball is longer than normal, the retinal tissue and the structures that support the optic nerve stretch and become thinner. This increases the risk of retinal detachment, cataracts, glaucoma, and even blindness. Myopia progresses rapidly, prescription glasses increase, the risk of these diseases is higher.
Children whose parents are nearsighted have a higher risk of developing myopia.
Researchers and clinical practice continue to search for more effective methods to prevent myopia from getting worse over time.
Correct prescription : It's important to make sure your child has the right prescription for their glasses or lenses, and more importantly, over-corrected lenses can actually contribute to progression of myopia. Atropine eye drops: Atropine eye drops are commonly used to dilate the pupils of the eyes as part of an eye exam or before and after eye surgery. In varying doses, depending on the individual case, Atropine eye drops can help slow the progression of nearsightedness. The exact mechanism for this effect is still poorly understood.

Spending time outside: Spending time outdoors during adolescence and early adulthood can help reduce the lifetime risk of nearsightedness. The researchers suggest that exposure to the sun's ultraviolet (UV) rays can change the molecular structure of the sclera and cornea, helping to maintain its normal shape. Dual-focus contact lenses: A new type of dual-focus contact lens has been shown to slow the progression of nearsightedness in children aged 8 to 12 years. Gas-permeable rigid contact lenses: With this method, you'll wear hard, gas-permeable contact lenses for several hours a day until the curvature of your eye is exposed. You then wear the lenses less often to maintain their new shape. If you stop this treatment, your eyes will return to their previous shape. Some studies show that this lens slows down the elongation of the eyeballs with myopia, reducing myopia. Here are a few numbers related to myopia:
66%: Myopia increased rate in the US from the early 1970s to the early 2000s 50%: The percentage of the world population will be nearsighted by 2050 4 out of 10: Percentage of adults in the US with myopia 1.25: Daily hours outdoors needed to reduce the chance of a child being nearsighted by 50% Vinmec International General Hospital offers customers Vision Package Refractive error control helps to screen for refractive errors (strabismus, nearsightedness, farsightedness, astigmatism, amblyopia) through general and normal eye exams, and periodic monitoring and management for 1 year for patients. have refractive errors.
