Presbyopia is a typical part of the aging process. [4] It occurs due to age related changes in the lens (decreased elasticity and increased hardness) and ciliary muscle (decreased strength and ability to move the lens), causing the eye to focus right behind rather than on the retina when looking at close objects.

The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye. Contact lenses are worn directly on the surface of the eye.
When refractive errors in children are not treated, the child may be at risk of developing ambylopia, where vision may remain permanently blurry.

Far-sightedness primarily affects young children, with rates of 8% at 6 years old and 1% at 15 years old. [9] It then becomes more common again after the age of 40, known as presbyopia, affecting about half of people. [4] The best treatment option to correct hypermetropia due to aphakia is IOL implantation. [2]
