Crushing of the dermis
The eye can be bruised or squeezed by a mechanical force from outside, such as a fist punch, a ball, a stone throw, etc. or by a storm. It is possible that the eye carries a serious injury of it, which can affect the eyelid, conjunctiva, cornea and sclera.
Usually a bruise is visible from the outside, as the eyelid is usually affected and swells, making it difficult to open the eye. However, this symptom known as “violet” does not say anything about the severity of the injury to the sclera, which is why an ophthalmologist should be consulted if necessary.
