Test for visual impairment

What is your visual acuity at distances? Try it out!


Download our model and print it out.


Fasten the page to an empty wall at eye level and step back 4 metres (5 steps).


Try to see in what direction the circular opening is pointing. Take note of the row that you can read clearly without any problems.


In which row were you no longer able to recognise the circular opening? The corresponding value describes your visual acuity (visus) for distance.

Visual acuity 1.2 to 1.5:

Congratulations! You have the proverbial „eagle eyes„. Nevertheless, you should not forget to visit your optician, ophthalmologist and optometrist regularly in order to monitor your outstanding vision.

Visual acuity 1.0:

Most likely, you do not need glasses. However, eyes can change over time and vision can decrease. Therefore regular examinations are advisable.

Visual acuity 0.8:

This is the limit for safe car driving. Nevertheless, you should have your eyes checked by a doctor or optician. Keep in mind that in the night or if there is glare, visual acuity is less than during daylight.

Visual acuity 0.4 to 0.6:

Your visual acuity seems to be alarmingly low. Have your eyes checked professionally as soon as possible. You need glasses, especially for driving a car.


Near- and farsightedness

If you notice that you cannot see well up close or at a distance, then it is likely that you have a visual impairment.

Nearsightedness or myopia

If you are nearsighted, then you can see well at short distances without glasses, but everything is blurry and unclear in the distance. The most frequent cause of this is an eyeball that is too long (longitudinal myopia) so that the image is created in front of the retina, and for that reason you cannot see it clearly.

Nearsightedness is measured in dioptres. It can be compensated for optimally with Rodenstock lenses with a minus effect – and you can once again fully utilise your vision potential.

Farsightedness or hyperopia

Farsightedness occurs in most cases by an eyeball that is too short (longitudinal hyperopia). The image is created behind the retina and is not sharp. Vision in the distance can usually be compensated for some time, but vision is unclear up close.

Just like nearsightedness, farsightedness is also measured in dioptres. It can also be corrected optimally with Rodenstock single vision glasses; however the lenses have a plus effect in contrast to nearsightedness.
