GLASSES AND CHILDREN |

Why does my child have glasses?
Children usually inherit glasses from their parents. If either parent has glasses, then there is a fair chance that at least some of your children will get it. If both parents have glasses, chances are that all children will have them too. But sometimes parents do not have glasses, apparently neither does anyone in the family, yet kids get it. This is also a possibility as heredity is not the only causative factor.. |

How do glasses help see clearly?
Rays of light form a point of focus on the retina, (sensitive part of eye) and the eye can see clearly without any aid. But in a myopic eye (short sightedness), the axial length of the eye is larger than normal thus rays of light do not form a point focus on the fovea, and thus objects are seen blurred. When we put a concave lens (minus number lens) in front of the eye, the rays of light falling on the eye, make a point focus on the retina thus enabling the eye to see clearly.
In a hypermetropic eye (long sightedness) the axial length of the eye is smaller hence rays of light falling on the retina do not form a point focus on the retina (fovea). But when a convex lens (plus number glasses) is placed in front of the eye, the eye can see clearly. |

What is Astigmatism?
The cornea has 2 radii of curvature – horizontal and vertical. When these 2 are not balanced, i.e. one meridian is steeper than other, the condition is called astigmatism. The patient perceives seeing shadows around objects or straight lines appear slanting. This is remedied by adding “Cylindrical lenses” which have power only in one meridian. |

Will my child’s number reduce if he/she wears glasses all the time?
Usually does not disappear only because the child has been wearing glasses all the time. As illustrated earlier, having glasses is an optical phenomenon, related to the length of the eyeball. As the child grows his eye balls also increases in length and hence till he/she is 18 years (in some cases 21 years), the number does not stabilize |

My child watches TV too much, does not eat carrots and vegetables properly. Is that why he/she has glasses today?
This is the most commonly asked questions. Just watching TV for long hour’s everyday cannot include a number in that eye. Similarly, vegetables, carrots, though contain vitamins and essential nutrients do not contribute towards needing glasses or otherwise. Similarly even if a child with glasses eats carrots regularly, the number will not disappear only because of this. |

Is it necessary for my child to wear glasses, though he/she is not complaining of eye strain or headache?
Yes. Depending upon the power of glasses whether plus or minus, your doctor will advice you regarding the wearing schedule. Remember, even by wearing glasses only some types of lazy eye can be prevented/cured. |

How can I get rid of my child’s glasses?
When the number stabilizes by 18-21 years (that is, there is no change in power atleast for a year or so) laser can be utilized to get rid of glasses. It is a very safe and effective method to get rid of glasses permanently.
