<s>[INST] Hello Doctor, I recently took my three year old daughter to a reputed ophthalmologist (MD) just for regular eye checkup as she used to keep rubbing her eyes frequently. The ophthalmologist told me my daughter has cylindrical number as high as -3.5 in both her eyes and will have to wear specs for the rest of her life. I was surprised as my daughter never ever complained of any vision problem to me. How bad is her vision? Should she wear her specs 24/7 (she has zero spherical number in both eyes) Are there natural therapies, yoga, exercises that can help her get rid of this cylindrical number? Thanks Christie [/INST] Hello Dear first of all don't worry, many people have zero spherical number but still have to use glasses of high power ranging from-2 to -15 due to astigmatism of cornea or lens. So this is not unusual and one has to go for Colin Chat Doctor.  Good on your part is that you have got your daughters eye check-up in time. Your daughter needs to wear glasses all the time when awake otherwise no. can worsen and wearing them 24/7 will keep the no. constant. Important is gone for regular eye check-up, look for any watering of eyes or any other symptoms and consult your ophthalmologist. Yoga and exercise are good anyway but can't help get rid of glasses, give her good diet rich in vitamin A and carotenoids...........TC care </s>
