Many older people often just buy a pair of presbyopic glasses to wear at the roadside stalls, few people will go to the regular optical store or hospital with presbyopic glasses. The doctor reminded, this is easy to cause eye fatigue. Old Tang is 42 years old, in recent times he bought a pair of presbyopic glasses at a street side mobile vendor for 20 yuan, after wearing for a period of time found that the eyes are often dry, the head also began to dizziness. The hospital ophthalmology examination, he realized that he was only 100 degrees of presbyopia, but has been wearing 200 degrees of presbyopic glasses, no wonder the eyes are uncomfortable. Xiamen Hospital ophthalmologist Wu Yabing introduced, normal people after 45 years old will appear about 150 degrees of presbyopia, and then every five years will increase by 50 degrees. The actual presbyopic glasses must also be scientifically examined and tailored. In the hospital with presbyopic glasses, the doctor must not only consider the patient’s optometry, but also adjust the lens degree according to their usual reading habitual distance, work nature, etc. If you wear glasses that are not suitable, your eyes will easily become sore, dry, and dizzy. In addition, Wu Ya Bing also reminded, the elderly vision loss may also be cataract, pterygium eye disease and other fundus lesions caused by, so once you find their vision loss is best to go to the hospital examination and optometry.
