QUARANTINE: A KEY MOMENT
Whether you have always had good distance vision without glasses, whether you are nearsighted, farsighted or astigmatic , around the age of forty no one escapes presbyopia !
Often, the first discomfort is felt after returning from vacation, when the light decreases, after summer or following a bout of fatigue. Suddenly, we can no longer read the newspaper, restaurant cards or notices. These small characters only become readable by holding them at arm's length in strong lighting.
Don't panic, it's normal and natural!
Why do we become presbyopic?
It all starts at birth with the lens, this intraocular lens essential for vision.
This strange organ that is the lens begins to age from birth. While it was vascularized during uterine life, it ceases to be so when the child lets out its first cry...
Subsequently, this lens behaves like a “tree trunk”. Over time, layers build up so that the lens thickens and stiffens . By losing its flexibility, it no longer bulges sufficiently and adjusts (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 his clear vision will be from 7 cm. A young adult of twenty years old will see clearly from 10 cm; at forty years old, he will see clearly from 30 cm; at fifty years old
50 cm then at 70 years old at 2 meters! The normal and comfortable reading distance is 33 cm, we understand that between 40 and 45 years old the arms give the impression of becoming too short!
In France, almost 30 million presbyopes are experiencing this difficult moment...
Presbyopia may occur earlier for people living at altitude or in hot countries.
In Africa and the Himalayas, we meet young presbyopes aged 35 years old. The culprits are heat and the amount of UV rays. This is why it is important to protect your eyes well from the sun, even in our latitudes.
How to recover your near vision:
Correcting presbyopia is, in principle, very simple. Since only near vision is disturbed, power must be restored to the eye only for close objects. The lens having lost its capacity for accommodation, we use an “optical addition” for this: reading glasses equipped with “magnifying” lenses (converging lenses) or fitted with digressive lenses for clear and clear near and intermediate vision. Varionet offers reading glasses with decreasing lenses from €39.00, frame and lenses included.
