Presbyopia

It is a condition in which the lens of the eye loses its ability to focus. This makes it difficult to see nearby objects. Presbyopia is a visual problem caused by aging that we usually notice from the age of forty. The oldest and simplest solution is the glasses, or the multifocal contact lenses. Through surgery there are temporary solutions, but you can also operate presbyopia permanently

Reason

The lens of the eye needs to change its shape to focus on objects that are nearby. The ability of the lens to change shape is due to the elasticity of the lens, which is slowly lost as people get older. The result is a slow loss of the eye’s ability to focus on nearby objects.
