Optiker oder nicht?

It is so that you should register with the ophthalmologist as up to 16. For the year of life, the pupils of a child should be wide-dip so that the natural accomodation of the ciliarmuscle is prevented. Your parents should accompany you to the appointment as you can see blurring until the next day. A sunglasses helps before glare.

This possibility does not exist in the optician, it measures the visual acuity, whereby the child can change the dioptrienzal due to the accomodation and this Nativ value is not the accurate Werrt for the glasses.

Would you try to measure the refraction (i.e. the dioptrics) of children without first expanding or expanding the pupils. to inhibit the lens play with it, one would possibly overlook very large deviations. Children can compensate up to 5 diopters for measurements without eye drops due to muscle work in the eye.

Compensate measurements without eye drops by muscle work in the eye.

Before examination with the skiascope (a slit-shaped light source) the eyes of the child are treated with eye drops, which extend the pupils and paralyze the ciliarmuscle. In the case of smaller children, the concentration of twice 0.5% cyclopentolate is chosen, and in the case of larger children the concentration of twice 1% cyclopentolate is chosen. After about 30 minutes of action after the second eye drops, the measurement can be started.

Cycloplegica are drugs that act on the nervous system and inhibit parasympathy, so that the accommodation is suppressed. The receptors of the ciliarmuscle and that of the pupil closer, the so-called musculus sphincter pupillae, are blocked (cycloplegia, mydriasis).
