What are the right glasses for presbyopia?
As the years go by and as you get older, it is inevitable to reduce the elasticity of your eye lens, as a result of which your visual acuity decreases. This is how presbyopia is created.
What are the right glasses for presbyopia?
The multifocal lenses (crystal or organic) of the glasses achieve the smooth transition from distant, middle and then near vision having different degrees in only one lens. They therefore provide a clear picture at all these distances. The main idea of their operation is not complicated and is perfectly synchronized with the movements of your eyes. Multifocal glasses are therefore considered to be as close as possible to normal vision after the onset of presbyopia.
Their lens is divided into three zones.
The upper field of vision. It is responsible for your clear distant vision, suitable for walking, driving.
The intermediate field of vision, between 1 meter and 40 cm. Helps to clearly distinguish objects that are in the middle distance, suitable for the computer, cooking, etc.
The lower field of vision. Allows you to see close objects clearly, suitable for reading.
Multifocal eyeglasses change the power of the lens from top to bottom and have evolved in recent years so much that not only with a pair to ensure accurate vision at all distances, but also to successfully cover the aesthetic part, since no there is a dividing line between near and far focus.

What are the disadvantages of multifocal glasses?
Like regular eyeglasses, multifocal glasses have their drawbacks:
. There is a restriction on the free movement of the eyes. In some activities you have to make a small movement with the head in order to see clearly and not just to move your eyes.
. The fields of vision are smaller at long and short distances compared to those offered by single-focus lenses.
