Near-sightedness (myopia)

A near-sighted person can see close objects very well. However, distant objects are blurry. The cause is an excessive refraction power of the cornea or lens in relation to the length of the eye.


Usually, the near-sighted eye has an above average length, so the sharp image does not reach the retina but is in front of the retina.

Far-sightedness (hyperopia)

Unlike near-sightedness, from an anatomical perspective the far-sighted eye is constructed slightly too short. The sharp image is only represented behind the retina.


Distance viewing is usually relatively good however, close objects are blurry.


Up to a certain age, far-sightedness can be compensated by consciously focusing (“accommodation"). But especially in children, this can result in strabismus.

Corneal irregularity (astigmatism)

Corneal irregularity can appear as an individual form of defective vision or along with near-sightedness and far-sightedness.


Instead of being perfectly round (ball-shaped), the cornea has a slight oval shape. Images are seen displaced or distorted (e.g. a dot is seen as a line or circles are perceived as ovals).


In the case of mild corneal irregularity the brain is still able to correct the distortion, so that initially, it is only perceived as a general inaccurate visual acuity.

Presbyopic eye, Vista Alpina Eye Center Valais


The ability to accommodate deteriorates, i.e. focusing on close objects declines. This visual impairment develops progressively starting at the age of 40.


The typical sign of presbyopia is the need to hold objects (book, watch) farther and farther away, to see them clearly.


As a person ages, this distance increases. Presbyopia can usually be compensated with suitable reading glasses.
