Hi there . A cylindrical refractive error causes visual distortion and some patients resort to things they believe would improve vision. However, the appropriate treatment is spectacle correction and if the power and axis is correct there should be no subsequent problems. A 5 year old child is a difficult candidate for vision assessment and the power has to be confirmed with the help of dilating drops. Ask your child and try to observe yourself if she seems to be experiencing any double vision, abnormal head position like a tilt or turn or any squint that is visible. This is to check if she has any muscle imbalance. Observe her while she touches her right eye. Is she occluding her eye as if she is trying to eliminate the image from the right eye? If none of the above apply to her she may be doing that out of a force of habit that continues even after correction of vision with glasses and you will have to tell her she should stop, perhaps by holding her hand and showing her how the vision is normal now.
