Contact lenses for astigmatism
An astigmatism is a common visual impairment. Depending on the severity, this leads to blurred or distorted vision. Astigmatisms are unrelated to age and in many cases occur in conjunction with short- or long-sightedness. An astigmatism can be corrected with contact lenses.
What is an astigmatism?
Normally, the curvature of the cornea is even – similar to a sphere. In an astigmatism, the shape is distorted – it is egg-shaped. Due to the misshapen surface of the cornea, the incoming rays of light are no longer all broken to the same extent. The light rays no longer meet at a single point, but rather form a bar or rod on the retina. In German, this is therefore also referred to as ‘rod-sightedness’.
Our eyes cannot compensate for an astigmatism independently. An astigmatism can be corrected with a pair of glasses or contact lenses. In the case of severe or irregular astigmatisms in particular, good vision can be achieved once more with a contact lens – often even better than with a pair of glasses. Various lenses can be used to correct an astigmatism – for example, toric lenses.
Spherical lenses correct short- and long-sightedness. It is also possible, however, to correct astigmatisms using soft or hard (rigid) toric lenses.
Custom-made contact lenses
The human cornea is like a fingerprint – it is unique. Custom-made contact lenses not only meet the needs of this uniqueness, but also the responsibility for the health of your eyes. Custom-made contact lenses ensure especially long-term compatibility and healthy eyes.
