MWei (F/11) came for follow up, existing glasses made with us 11 months ago, with complaints of blurry far vision looking at whiteboard/projector screen at school. She wears her glasses to school only. When prompted whether or not she feels removing glasses to see near is more comfortable, her mother said that she has asked her to not wear her glasses always. Mother also reported that she will hold her phone very close to see.
