As people age, the elasticity of the lens decreases and the ability of the eye to focus also diminishes, leading to presbyopia. According to the largest portal website in South Korea, "naver", there are 7 symptoms that indicate presbyopia. If you have 3 or more of these symptoms, you should be cautious.
1. It is difficult to see the buttons or text on a smartphone without glasses.
2. It takes longer to focus when looking at objects at different distances.
3. It is easy to feel drowsy when reading.
4. Headaches occur when working at a close distance from objects.
5. Mistakes are frequently made when doing detailed work.
6. Squinting is necessary to see clearly at a close distance.
7. Books or phones need to be held far away to see the words clearly.
Some bad habits can accelerate the development of presbyopia. For example, staring at a phone or computer for a long time reduces the blink rate, causing eye fatigue and making focusing more difficult. This leads to excessive tension in the lens and eye muscles, and insufficient lubrication of the tear film. This can generate reactive oxygen species, which can damage normal eye cells and accelerate the development of presbyopia.
