Presbyopia is a normal physiological process, and the degree of presbyopia is related to age. For example, at the age of 45, presbyopia is 150 degrees.

If you insist on not wearing reading glasses, you will not be able to adjust the exhaustion of the ciliary muscles. It will definitely aggravate reading difficulties, produce dizziness and many other symptoms, which will affect your life and work. This is very unwise. Therefore, the presbyopic glasses are ready to be matched immediately, don't delay.

As the elderly age, the degree of presbyopia will also increase. Once the reading glasses are not suitable, they must be replaced in time, otherwise it will bring a lot of inconvenience to the life for the elderly, and will accelerate the degree of presbyopia. At the same time, presbyopic lenses have a limited life span. If they are used for a long time, the lenses will suffer from scratches and aging, which will reduce the amount of light passing and affect the imaging quality of the lenses.

Reading glasses are only suitable for looking at close objects, and should not be worn when looking at distant or normal objects. It is advisable to wear reading glasses for a long time regardless of time, which may cause problems such as blurred vision, dizziness, and decreased eye accommodation.
