Thank you so much:


Sudden constriction of left eye with no significant change in vision can be normal. Considering that you have uneven reaction of the pupil to light/night stimulation and focusing difficulty for few minutes in the dark, I would suggest that you follow-up with your eye doctor for closer evaluation under the slit-lamp, along with a complete neuro-ophthalmologic and dilated exam.


In the meantime, I suggest that you use over the counter preservative free tear drop such Genteal tears or Refresh plus 4 times daily. In general, unintentional eye rubbing or irritation can briefly affect the sensitivity of the iris nerves, and hence size of pupil ti light effect. However, slow re-adaptation (accommodation) in the dark can be due to aging iris or early eye lens changes, both of which are not harmful, but should be closely evaluated by your eye doctor.
