Blepharospasm is often associated with dry eyes, but the causal mechanism is still not clear. [16] [8] Research in New York and Italy suggests that increased blinking (which may be triggered by dry eyes) leads to blepharospasm. [24] [25] A case control study in China found that blepharospasm aggravated dry eyes. [26]
Spasm of accommodation is frequently resistant to treatment. However, some patients do find relief through the use of daily eye dilation with cycloplegic drops. One side effect of cycloplegic drops is that they often have BAK as a preservative ingredient, which, with daily use, can erode the tear shield:
Tardive dyskinesia is characterized by repetitive, involuntary movements, which occurs following treatment with medication (hence the term tardive). [9] Some examples of these types of involuntary movements include: [10] Grimacing; Tongue movements; Lip smacking; Lip puckering; Pursing of the lips; Excessive eye blinking
Studies suggest [26] that adults can learn to maintain a healthy blinking rate while reading or looking at a computer screen using biofeedback. Eye blinking can be a criterion for diagnosing medical conditions. For example, excessive blinking may help to indicate the onset of Tourette syndrome, strokes or disorders of the nervous system.

Accommodative excess has traditionally been defined as accommodation that is persistently higher than expected for the ...
Nowhere near as often as we do. Humans tend to blink between 15-20 times a minute, and as we've already mentioned, it's an essential thing we do automatically to keep our eyes in good condition.
Mild conjunctivochalasis can be asymptomatic and in such cases does not require treatment. Lubricating eye drops may be tried but are often ineffective. [8] If discomfort persists after standard dry eye treatment and anti-inflammatory therapy, surgery may be undertaken to remove the conjunctival folds and restore a smooth tear film.
