The relationship between age and presbyopia generally follows the following rules:
That is, for every 5 years of age, the power of reading glasses increases by 50 degrees. Generally, presbyopia will stop increasing around the age of 70, so the height of reading glasses should not exceed 400 degrees.
Why presbyopia? Will it get darker the more I wear it?
Presbyopia is caused by the gradual decrease of the elasticity of the lens in the eye as the age increases, and the muscle strength of the ciliary body gradually weakens. When looking at near objects, the lens cannot become convex, causing the image of near objects to fall behind the retina. Generally, for people over 45 years old, if their vision used to be normal when seeing near and far, but now they see distant objects clearly but close objects become unclear, when reading, they should hold the book further away or use more lighting. You can only see it clearly when you are older. In this case, you have presbyopia. Why does presbyopia occur early in some people and later in others? This is because some people are myopic and have longer eyeballs. When looking at distant objects, the image falls in front of the retina and they cannot see clearly. When looking at nearby objects, they have to hold the object closer to see clearly. , such people will develop presbyopia later, and some people originally have hyperopia, and their eyeballs are short. The image of distant objects falls behind the retina, and they need to move the object farther away to see clearly. Such people will have presbyopia. Will be sooner. In order to avoid worsening the degree of presbyopia, some people hesitate to wear reading glasses. In fact, this will fatigue the eyesight, cause headaches, and dizziness, which is detrimental to health in the long run. Whether you wear it or not, the degree will always increase with age. This is an objective law. Therefore, when presbyopia occurs, it is still necessary to wear spectacles with appropriate prescription to facilitate life and work and prevent the prescription from deepening too quickly.
