Many older people are complaining that they are becoming more and more dizzy and have difficulty reading newspapers. Presbyopia is medically known as presbyopia and is mostly seen in middle-aged and older people over the age of 40. Presbyopia is the result of hardening of the lens, weakening of the elasticity, and reduced contraction of the ciliary muscle, resulting in reduced adjustment and distant shift of the near point, which leads to difficulties in seeing things at close range. People with presbyopia often feel blurred when looking at fine print and often involuntarily move the target farther away to reduce the adjustment burden and eliminate blurred vision and eye fatigue. In the case of presbyopia without glasses, even if you can barely see the near target, it is mostly due to forced adjustment and excessive contraction of the ciliary muscle, which can produce various phenomena of visual fatigue, such as headache, brow drop, heavy eyelids, sore eyes, blurred vision, etc. Presbyopia is irreversible, and the better the vision, the more pronounced the symptoms of presbyopia tend to be. An effective way to treat presbyopia is to compensate for the patient’s lack of adjusting power with appropriate convex lenses. If you already have presbyopia, it is unwise to force yourself to not wear presbyopic glasses, which can lead to excessive ciliary muscle fatigue, aggravate reading difficulties, and produce many symptoms such as dizziness and eye swelling, affecting your life and work. Therefore, presbyopia glasses when the match that do not delay. After growing older, the original presbyopic glasses are not enough, and should be replaced in time. The presbyopia glasses should also be professionally examined first.
