🔍 “I heard that people with myopia won’t develop presbyopia as they age, and that the two can cancel each other out?”

No, they cannot!

Myopia and presbyopia are two different vision problems and cannot cancel each other out. Myopia and hyperopia are “refractive errors,” meaning the eye cannot accurately focus distant images on the retina, affecting the clarity of viewing distant objects. Presbyopia, on the other hand, occurs due to a decline in the eye’s focusing “accommodative ability” as we age, leading to difficulty focusing on nearby objects and resulting in a “blurry” vision. It typically begins to appear after the age of 40.

👀 “Why does myopia sometimes seem to offset presbyopia?”
Many people have heard the saying that “myopia can offset presbyopia,” but this is actually a common misconception. In the early stages of mild presbyopia, if a person also has mild myopia, both conditions affect near vision, which may create the illusion that they are “canceling each other out.”

However, as age increases, the degree of presbyopia gradually worsens to moderate or even severe levels, while the degree of myopia may not increase at the same rate. At this point, the vision problems caused by the two conditions can no longer “offset each other.” The older a person gets, the more apparent the difference in severity between myopia and presbyopia becomes, making it even less likely for them to correct each other.

💡 Important Facts:
✅ Presbyopia is a natural degenerative process: Whether you have myopia, hyperopia, astigmatism, or normal vision, presbyopia is unavoidable. The only difference is that people with originally normal vision or hyperopia tend to notice the symptoms of presbyopia more easily.
✅ Besides presbyopia, many other conditions can cause vision problems, such as cataracts, glaucoma, and diabetic retinopathy. Regular eye examinations are crucial!
✅ Instead of ignoring it, take proactive steps: Many people, resistant to aging, mistakenly believe that “wearing presbyopic glasses will worsen their vision.” They would rather endure eye fatigue, pain, and discomfort than address their presbyopia. This mindset not only fails to improve vision but may also affect daily life. If vision problems are already causing difficulties in daily activities, seeking professional help and choosing appropriate corrective methods is the best solution.
