QUARANTINE: A KEY MOMENT
Whether you have always had good vision from afar without glasses, whether you are nearsighted, farsighted or have mild astigmatism , around forty no one escapes presbyopia !
Often, the first discomfort is felt when returning from vacation: when the light decreases, after summer or following a sudden fatigue. Suddenly, you can no longer read the newspaper, restaurant menus or notices just by holding them at arm's length.
Don't panic, it's normal and natural!
Why do we become presbyopic?
It all starts the very moment we come into the world with the crystalline lens, the intraocular lens essential to vision.
This strange organ that is the lens began to age from our birth. While it was vascularized during uterine life, it ceases to be so when the child utters its first cry...
Subsequently, this lens behaves like a tree trunk. Over time, layers build up causing the lens to thicken and stiffen . By losing its flexibility, it no longer bulges sufficiently and accommodates (focusing) with difficulty: we see less and less well up close.
Thus, a two-year-old child sees clearly from 5 cm, at six years old his clear vision will be from 7 cm. A young adult of twenty will see clearly from 10 cm; at forty, he will see clearly from 30 cm; at fifty years old
50 cm then at 70 years at 2 meters! The normal and comfortable reading distance being 33 cm, we understand that between 40 and 45 years the arms give the impression of becoming too short!
In France, almost 30 million presbyopes are going through this difficult time...
Presbyopia can be earlier for people living at altitude or in hot countries.
In Africa and in the Himalayas, one meets young presbyopes aged 35 years. The culprits are the heat and the amount of UV. This is why it is important to protect your eyes well from the sun, even in our latitudes.
How to recover near vision:
The correction of presbyopia is, in principle, very simple. Since only near vision is disturbed, it is necessary to restore its power to the eye only for near objects . Since the lens has lost its ability to accommodate, an “optical addition” is used for this: reading glasses fitted with “magnifying” lenses (converging lenses) or fitted with degressive lenses for clear and sharp near and intermediate vision. Varionet offers reading glasses with degressive lenses from €39.00 frame and lenses included.
