The poor eyesight that developed cataracts can cause a person to suffer from can, in some cases, cause disequilibrium. However, it isn’t known to cause vertigo.
Disequilibrium is a loss of the body’s equilibrium, a feeling of unsteadiness or imbalance; effecting a person’s depth perception, that’s often accompanied by a general sense of spatial disorientation. It can often leave sufferers feeling like they’re about to fall. Some people describe it as a feeling that the floor is tilted and balance is difficult to achieve as the spatial awareness to know where the floor is, is lacking. Sometimes it can also leave a sufferer feeling a little like they’re floating.
Vertigo, on the other hand, is an abnormal sense of motion, the main symptom of which is usually to feel that everything around you is spinning. It can also give a sufferer the impression that everything is moving around them. Sometimes leading to vomiting and loss of hearing, vertigo is usually caused by problems with your inner ear; often caused by infection. Attacks can last from a few seconds to several hours, or, in severe cases, even days or months.
The NHS advises that most cases of vertigo will get better and go away without needing any treatment(1).
Cataracts are not a known cause of vertigo as it isn’t a condition that is related to the eyes.
