老人随着年事增高,肌体衰弱,患眼病也较普遍,易患以下几种眼病:1.老花眼老花眼是一种“能远怯近”的疾病,是由老年性晶状体硬化与睫状肌调节功能减弱所致。常有眼疲劳、视远清晰、视近模糊等症状。对于这种现象,需用凸形的球镜片来补偿调节视力的不足,可根据个人的具体情况验光配镜。2.青光眼青光眼是一种失明率极高的严重眼病。它的发生与年龄的增长成平行关系。由于老年人晶状体体积及重量的增加,束膜的增厚,前房变浅,常可形成生理性瞳孔阻滞,导致房水的循环不畅,加上某些外界的不良刺激,如疲劳、情绪过度激动等原因使青光眼更易发生。它一般起病较急,有头痛、眼珠胀痛、呕吐、视力明显下降、视野缺损等症状,最后引起眼底视神经不可逆性损害而失明。对于这种眼科急症,要争取 Elderly with age, increased body weakness, eye disease is also more common, susceptible to the following types of eye disease: 1. Presbyopia Presbyopia is a “far scared to death,” the disease is caused by senile lens sclerosis and ciliary muscle regulation Due to weakening function. Often eye fatigue, as far as clear, as nearly fuzzy and other symptoms. For this phenomenon, the need to use convex spherical lens to compensate for the lack of vision adjustment, according to the specific circumstances of individual optometry. 2. Glaucoma Glaucoma is a serious eye disease with a high rate of blindness. It happens in parallel with the growth of the age. Due to the increase of the volume and weight of the lens in the elderly, the thickening of the tunica albuginea and the shallow anterior chamber may often form physiological pupillary block, resulting in poor circulation of the aqueous humor, plus some adverse stimuli such as fatigue, Excessive emotional excitement and other reasons make glaucoma more likely. It is generally more acute onset, headache, eye pain, vomiting, decreased visual acuity, visual field defects and other symptoms, and finally caused irreversible damage to the fundus optic nerve blindness. For this eye emergency, to fight
