stigmatism is a widespread ametropia. However,
it is often very weak, so that no correction is necessary. If the cornea is slightly curved, spherical contact lenses are sufficient. You swim on a tear film.
It adapts to the curvature of the cornea and thus assumes a toric shape. If the astigmatism is less than 0.5 diopters, it does not matter whether spherical or toric contact lenses are worn.
The difference between the two variants is the shape. The former are ordinary contact lenses with a simple round curve, while the toric variants are more complex.

toric contact lenses
compensate for astigmatism approximately up to a corneal curvature of 0.75 diopters,
hard lenses up to 2.50 diopters. If the corneal curvature is more pronounced, spherical lenses are not sufficient. Here toric contact lenses are necessary to ensure optimal compensation. In particularly severe cases, you may not be able to correct the visual defect. Soft spherical contact
