Myopia and treatment
The main symptom of myopia is much decreased vision and near vision to normal, that fuzzy look far to see near objects clearly. To see distant objects will be dispersed aperture. Some people often squint to see things, because it will narrow the palpebral fissure, so that pupils narrow to enhance vision. Often blind eye, the eye muscles inside and outside the transition stress, prone to visual fatigue. Sometimes in order to see objects near the front of the Oakley Sunglasses move, the result will be caused by fatigue due to increased regulation, decreased vision.
The treatment of myopia
1, with glasses: negative lens to correct myopia with to achieve normal vision (1.0), is one of the most common and most economical way
2, the contact lenses: for anisometropia, high myopia, keratoconus, or some occupation.
3, surgical treatment: the current domestic excimer laser (PRK), radial keratotomy (RK) scleral reinforcement, etc., for more than 18 years of age, degree of stability of the patient.
What formal steps optometry points?
Objective is divided into regular optometry optometry, subjective refraction, tried on three steps.
Objective optometry: a retinoscopy (doctors see patients through the eyes mirror retinoscopy to determine the degree), computer optometry, provide the approximate degree of refractive patients.
Subjective refraction: the adjustment to relax, red and green test, eyes balanced, composed of many steps in order to find the exact prescription.
Try them: look through the objective and subjective refraction results so that patients try them, if necessary, make some adjustments, so that patients can see clearly, to see lasting, comfortable seen so far.
How to prevent myopia
1. Note that eye health
2. Insist on doing eye exercises
3. Work and rest, adequate sleep
4. Attention to nutrition, exercise, enhance physical fitness
5. Regularly to professional visual acuity optical company, found that reduction should be corrected in time to prevent myopia
Read and write, “second,” “Six Do not”
“Second, we must”: to be read and write correct posture, keeping “one foot one inch punch”, that the eyes from the book goes, the Armani Sunglasses body punch from the edge of the table, fingers an inch from the tip continuous reading for about an hour to break .
“Six Do not”: Do not read lying down do not walk to read do not travel read not to read in direct sunlight Do not read under dim light not tilted his head to write.
Avoid wearing glasses
Dirty lens: lenses get dirty if it will affect the light to pass through, depending on the material increase in burden.
Frame twist: this would not work is the lens optical center hole of Ke, easy to produce prism effect, damage eyesight.
Far and near universal: general mild myopia, glasses should be worn when in use as much, depending on the time that is nearly removed, or the regulation of ciliary muscle would increase the burden, deepen myopia.
By wearing glasses: this practice, as other people’s glasses with himself in refractive error, Ke distance optical center and the axial deviation of astigmatism, often have an extremely harmful visual impact.
Not accustomed to the phenomenon of early glasses
l, “glasses” when first worn, far from clear to see and feel things smaller, narrow and not used to see the immediate cause, and dizziness phenomenon.
2, “farsightedness glasses” when first worn, almost clear to see, feel what magnification to see much anti-sense fuzzy and head hair up phenomenon.
3, “astigmatism glasses” beginning to wear, the visual distortion, uneven walk that ground, and head up the phenomenon of dizziness.
4, “the old optical glasses,” people over four years old, wearing glasses can use this in less than a foot away from work and reading, can not wear away.
These are not used to the phenomenon, often worn around l-2 weeks, will gradually normal up, and must always wear (except for the old optical glasses.)
Glasses also decreased visual acuity
General may have the following reasons:
l, with the glasses was considered perfectly safe to ignore with eye health, resulting in increased myopia
2, some of convenience or Chanel Sunglasses greed will be declared, the preparation of the glasses are not suitable for their own long period of time, eye fatigue, eye drops
3, some young people to wear glasses as a burden or that affect the appearance, sometimes wearing, and sometimes do not wear, so that the regulation of the eye in an unstable state, but also will enhance the degree
4, there are those with high myopia, the degree to deepen and wearing glasses nothing to do with the family heredity.
