Presbyopia is a physiological phenomenon that is neither a pathological condition nor a refractive error. It is a visual problem that inevitably occurs when people enter the middle and old age. As we age, the ability to adjust our eyes gradually declines, making it difficult for patients to be near-sighted to work in close quarters. After presbyopia appears, we need to prepare presbyopic glasses in time to reduce the impact on life and work, but are you also confused about how to choose half frame reading glasses, half eye reading glasses, round reading glasses, rimless reading glasses? Let us understand how to choose reading glasses.
1. Do not choose reading glasses at will
The survey found that many middle-aged and elderly people often buy a pair of reading glasses casually after they have symptoms, and feel that it is okay to see clearly. Some citizens said that the elderly buy the reading glasses only occasionally, there is no need to spend energy and time to check the optometry. According to the hospital's ophthalmologist, "most of the patients who come for optometry every day are teenagers, and the elderly are equipped with reading glasses for optometry, which only accounts for a small amount of outpatient visits."
Experts remind that buying and wearing presbyopic glasses at will can harm eye health. "A dozen yuan of reading glasses sold on the stalls seem cheaper but the quality is difficult to guarantee." A shop assistant at a chain of eyewear stores said, "If consumers wear reading glasses with quality problems for a long time, it will cause irreversible damage to the eyes. "
2. Check the fitting reading glasses beforehand
Before choosing reading glasses, go to the hospital for a comprehensive eye examination, including distance vision, near vision, intraocular pressure and fundus examination. Only after excluding cataracts, glaucoma and some fundus diseases can the degree of optometry be determined. Presbyopic power changes with age, so it is best to go for optometry every three to five years.
3. Reading glasses cannot be worn all the time
As the elderly increase in age, presbyopia will deepen. Once the reading glasses are not suitable, they must be replaced in time, otherwise it will cause a lot of inconvenience to the life of the elderly, and will also accelerate the degree of presbyopia. At the same time, the life of presbyopic lenses is limited. If they are used for a long time, the lenses will have scratches, aging and other phenomena, resulting in a decline in light flux and affecting the imaging quality of the lenses.
4. Wear reading glasses on appropriate occasions
Round reading glasses are only suitable for looking at objects at close range, and should not be worn when looking at distant or normal things. It is advisable to wear reading glasses for a long time regardless of time, which will cause dizziness, blurred vision, decreased eye adjustment and other problems.
5. Do not use magnifying glass to replace presbyopia
Old people often use magnifying glasses instead of reading glasses. The magnifying glass folded into a reading glasses is equivalent to 1000-2000 degrees, so "pampering" the eyes for a long time, it is difficult to find the right degree when you add the reading glasses.
6. Choose a reading glasses that can filter ultraviolet rays
The elderly should wear a pair of glasses that can effectively filter ultraviolet rays and have a protective function, which can prevent senile eye diseases such as cataracts and macular degeneration of the fundus. The finished mirrors sold at this stage are all processed in strict accordance with national standards. And there is a certificate of qualification and a range of applicable pupil distances.
