Abstract: suffering from ametropia, the most important performance is the decline of vision. Due to the obvious decline of vision, patients can’t see and blur a lot of things, which leads to the decline of quality of life, learning and work efficiency, and it will be very inconvenient to participate in various social activities.
eye problems, regardless of size, must be taken seriously! The occurrence of ametropia is due to many reasons. Of course, it will also cause many diseases. Therefore, treatment and prevention are comprehensive! Then follow Xiaobian to understand the hazards, preventive measures and treatment of ametropia, and better participate in eye protection!
1. You should often do eye exercises, press your temples, or close your eyes and refresh your mind. Closing your eyes and refresh your mind can not only give your eyes a full rest, but also rest your brain.
2. Don’t lie down and read while walking, and don’t read when taking the bus. Generally, when reading, get up and move every hour, cover your eyes with your palms, gently massage, and then look away. The farther you look, the better. It’s best to look at green plants, because green plants can absorb ultraviolet rays in strong light, Reduce or eliminate the harmful effects of ultraviolet rays on human eyes and give eyes a comfortable feeling.
the harm of ametropia
harm 1: vision loss
suffer from ametropia, the most important performance is vision loss. Due to the obvious decline of vision, patients can’t see and blur a lot of things, which leads to the decline of quality of life, learning and work efficiency, and it will be very inconvenient to participate in various social activities.
harm 2: strabismus prone
people suffering from ametropia should not only wear glasses, but also prone to strabismus. Strabismus mainly occurs in people with moderate or severe hyperopia in both eyes.
harm 3: Amblyopia
amblyopia is a serious eye disease. Once it is not treated in time, it may lead to blindness. Amblyopia often occurs in people with moderate or severe astigmatism in both eyes. Harm 4 of
: visual function of eyes is impaired.
suffer from ametropia, which will damage the visual function of both eyes, that is, there is no accurate stereoscopic function or complete loss of stereoscopic function, resulting in the patient being unable to engage in and competent for the work requiring accurate positioning and fine operation.
mild and moderate myopia, can be combined with moderate concave lens to correct vision. High myopia often feels too small, dizzy and difficult to see near objects after wearing glasses. Its degree should be reduced as appropriate, or wear corneal contact lenses, but if the latter is not handled properly, it can cause a series of corneal complications.
radial keratotomy; Making 8 ~ 16 radial incisions around the cornea (outside the pupil area) can flatten the center of the cornea, reduce the diopter of the eye and achieve the purpose of correcting myopia. Generally, the correction effect of 2 ~ 8D myopia is good. The correction effect is related to the depth of incision, the number of radial corneal incision and the size of central transparent area. However, this kind of operation causes certain damage to the cornea. Improper treatment can lead to serious complications such as corneal perforation, endothelial decompensation and infection, and the long-term effect has not been fully determined, so we should take a cautious attitude towards this operation.
hyperopia, if the visual acuity is normal and there are no conscious symptoms, it does not need to be treated. If there are visual fatigue symptoms or visual acuity has been affected, wear appropriate convex lens for correction. Children with high degree of hyperopia, especially those with esotropia, should be equipped with glasses as soon as possible. With the development of eyeballs, the degree of hyperopia of children tends to decline gradually. Therefore, it is necessary to check once a year in order to adjust the degree of glasses at any time. In addition to wearing convex glasses, corneal contact lenses can also be used for correction.
are generally mild and asymptomatic, otherwise they should be corrected with cylindrical transparent lenses, concave cylindrical lenses for myopia astigmatism and convex cylindrical lenses for hyperopia astigmatism.
