Have you ever had the experience of holding up your phone and gradually moving it away from your line of sight, extending your arms longer and longer; Do you prefer a brighter background light when reading, or do you take off your nearsighted glasses and get closer to see clearly and comfortably? The above situation is actually a visual signal sent to us by the eyes - presbyopia. Presbyopia, commonly known as "presbyopia" or "presbyopia," refers to a phenomenon in which the ciliary muscle strength of the eye weakens and the crystalline lens hardens with age, leading to physiological decline in eye regulation and resulting in close range eye problems. In daily life, there are still some misconceptions about presbyopia, such as "wearing reading glasses will increase the degree" and "sudden reduction of presbyopia is a sign of eye improvement". Below, we will take you through the truth one by one. Misconception 1: Presbyopia can be cured. The truth is that presbyopia is a physiological aging that cannot be "cured" or reversed at present. All corrective measures are aimed at "compensating" for the loss of eye adjustment ability, making it relatively comfortable to use, and improving the quality of life. Any method claiming to 'cure' presbyopia is unscientific. Misconception 2: People with myopia will not experience presbyopia. The truth is that myopia and presbyopia are two different types of visual problems, and there is no direct causal relationship between the two. People with myopia can also experience presbyopia, but when using their eyes at close range, the degree of myopia (negative lenses) partially offsets the degree of presbyopia (positive lenses), allowing them to see clearly without wearing glasses; However, when looking at a distance, myopic individuals also need to wear nearsighted glasses. Misconception 3: Just buy a pair of reading glasses. The truth is that reading glasses need to be customized according to personal visual needs, close range, and pupil distance. Randomly purchasing or sharing reading glasses with others may result in mismatched prescription and inappropriate pupil distance. Long term use can easily cause dizziness, eye swelling, and fatigue. I suggest everyone standardize the fitting of reading glasses. Misconception 4: After wearing reading glasses, the degree of presbyopia will increase. The truth is that the degree of presbyopia will slowly deepen with age and generally stabilize between the ages of 60 and 65. The development of presbyopia is not related to the wearing of presbyopia glasses themselves. Wearing appropriate reading glasses is to enhance visual effects and alleviate visual fatigue. Regular check ups and timely replacement of reading glasses are crucial. Misconception 5: It is a misconception to wait until the age of 50-60, when you can't see clearly, and then wear reading glasses to reveal the truth. Once symptoms of near vision fatigue appear, proactive correction should be taken. Delaying or forcefully not wearing reading glasses not only affects work efficiency and quality of life, but also forces the eyes to be in a long-term state of excessive adjustment and tension. Pay more attention to fatigue, and may even trigger or worsen other eye problems. Misconception 6: The sudden reduction of presbyopia is due to the improvement of the eyes. The truth is that presbyopia itself does not decrease. It may be due to the hardening and opacity of the lens nucleus, which deepens myopia and offsets some presbyopia. This is not true visual recovery, but may be an illusion caused by cataracts. In addition, the fluctuation of blood sugar in diabetes patients may also temporarily affect the lens diopter. In this case, you should seek medical advice in time to check eye and systemic diseases. (New Society)
