Refractive errors are mainly characterized by blurred vision during distance and/or near vision. Sometimes, hypertonic ciliary muscle may cause headache symptoms. Occasionally, prolonged staring may cause dry eye surfaces, causing eye irritation, eye itching, visual fatigue, foreign body sensation, and red eyes. <br><br>Children's refractive errors are mainly characterized by frowning and excessive blinking or rubbing while reading. <br><br>Correction of myopia needs to wear a concave lens of appropriate power to make the parallel rays diverge before entering the eye and focus on the retina after passing through the refractive system of the eye. <br><br>In the same way, correcting presbyopia needs to wear a convex lens of appropriate power, and correcting astigmatism needs to wear a cylindrical or spherical lens. <br><br>People with astigmatism should wear corrective glasses, even if they have a mild degree, if they have decreased vision or symptoms of asthenopia. <br><br>People with high astigmatism or irregular astigmatism can consider wearing rigid contact lenses or undergoing excimer laser surgery when the lenses cannot be corrected. <br><br>Warm reminder: The pictures contained in this report are all distributed in order to cooperate with the text and cannot be used for secondary diagnosis or any other medical judgment purposes. <br>Radiology

Responsion is mainly indicative of far-sightedness and/or ambiguity of near-sightedness. Sometimes, high lash muscle dystatics can cause headache symptoms. Occasionally, prolonged gaze can cause dry eye surfaces, causing eye irritation, itchy eyes, visual fatigue, foreign body feeling, and redness.<br><br>Children's relegation is mainly indicative of frowning and over-blinking or rubbing their eyes while reading.<br><br>The treatment of myopia eye needs to be accompanied by a concave lens of the appropriate degree, so that parallel light disperses before entering the eye and focuses on the retina after the eye retractation system.<br><br>Similarly, the treatment of far-sighted eyes needs to be accompanied by a suitable degree of convex lens, the treatment of astrology needs to be accompanied by a column mirror or cylindrical mirror.<br><br>People with astres eyes should wear corrective glasses even if the degree is very light, if their vision is impaired, or if they experience symptoms of visual fatigue.<br><br>People with high or irregular astration eyes may consider wearing hard contact lenses or quasi-molecular laser surgery when the lenses are incurable.<br><br>Tip: The images contained in this report are issued in conjunction with the text and cannot be used for secondary diagnosis or any other medical judgment purposes.<br>Radiology

The main characteristics of ametropia are blurred vision at distance and / or near. Sometimes, too much tension in the ciliary muscles can cause headaches. Occasionally, long gaze may cause dry eye surface, eye irritation, itching, visual fatigue, foreign body sensation and redness.<br>Children's ametropia is mainly characterized by frowning and excessive blinking or eye rubbing.<br>It is necessary to wear a concave lens with appropriate degree to make the parallel light diverge before entering the eye and focus on the retina after passing through the refractive system.<br>In the same way, the correction of hyperopia needs to wear appropriate degree convex lens, and the correction of astigmatism needs to wear cylindrical lens or spherical lens.<br>People with astigmatism, even if the degree is very light, should also wear corrective glasses, if there is a loss of vision, or visual fatigue symptoms.<br>People with high astigmatism or irregular astigmatism, when the lens can not be corrected, can consider wearing rigid contact lenses or excimer laser surgery.<br>Warm tips: all the pictures in this report are for the purpose of matching with the words, and can not be used for secondary diagnosis or any other medical judgment purposes.<br>Radiology Department<br>
