Until recently, I enjoyed an excellent vision and the pleasant condition of not having to put any visual aids in front of or in my eye. And even today, the skills to see the distance are excellent.
But that should not protect me from “presbyopia”.
On the one hand, this means “age-related long-sightedness” and on the other hand a detailed visual test for me.
In the past months I noticed that I had to stretch out my arms when reading something. That drove me into the arms of the local optician. Age-related long-sightedness should also be the diagnosis after an in-depth test. But what exactly is that?
Basically, it means no more than the close-up is no longer sharp.
Prerequisite for sharp vision is a picture that is projected onto the retina. If this does not work optimally, a blurred image is produced. In the best case the light strikes as a point on the retina.
The reason for this is the decreasing accommodation capacity of the eye in old age.
What is accommodation?
Our eye lens is flexible. It adjusts its shape to adjust the refractive power of the light at different viewing distances and to allow a “sharp image”.
As the age progresses, the lens loses its flexibility. The angle of refraction of the light can no longer be controlled as well, and the blurred vision arises. In addition, the ciliary muscles, to which the lens adheres, no longer have the force which they still had in times of youthfulness in order to move the lens sufficiently flexibly.
In the case of the slight age-related long-sightedness, which I had in my case, I left the local optician with a fashionable visual correction on my nose after a short time. This ensures more relaxation at work and when reading. For anything else wearing glasses is not necessary yet.
