What is presbyopia?
Presbyopia is caused by the loss of elasticity of the crystalline lens, which is the lens that allows us to focus on objects for near vision. As it becomes stiffer, we lose the ability to see objects at close range and have to move them farther away in order to see them clearly.
Can eyestrain increase if I don’t wear glasses?
No, wearing glasses or not, neither stops nor increases the progression of presbyopia.
It is a slow but irremediably progressive process.
Is it preferable to wear glasses?
The use of glasses is preferable whenever the patient has limitations to perform their activities.
The person will be much more comfortable and will avoid problems derived from the effort to see up close (headache, dry eye due to lack of blinking, blepharitis, etc.).
Can presbyopia be prevented?
It cannot be prevented. Everyone gets presbyopia.
The age range is very variable, from 40 to 45 years old, there may be patients with a lot of functional reserve of accommodation who may get it later, but that is exceptional.
Is it hereditary?
It is not hereditary. It is a consequence of the aging of the crystalline lens, it is not due to a genetic problem that can be transmitted from parents to children.
