Presbyopia
Presbyopia develops with aging and it is the difficulty in seeing close objects. In young people, the lens of the eye is elastic and adapts easily, providing a clear view of nearby objects. With age, this elasticity decreases and near vision becomes difficult. Therefore, similar to hyperopia, rays from nearby objects are focused behind the retina. It begins at the age of 35 to 40 and generally progresses until the age of 60. Glasses or contact lenses can be used in some patients. There is also the possibility of refractive surgery for presbyopia. Especially in hyperopia and astigmatism, when there is a high difference between the two eyes, one eye may have a permanently low vision level because the eye that is healthier tolerates the other for an extended period of time and thus the visual impairment is noticed late. This is called amblyopia, or lazy eye.
