It could be due to dryness or early fatiquability due to nutritional deficiency or myasthenia gr avis.
Pl ease take ink or tab methyl cobalamine 1500iu on alternate for 3wks .and put lubricant eye drops e.g. teardrop 2to3 times daily.
If still the problem persists then consult an ophthalmologist or a neurologist.
