+☆ may under-correct by +1.00 to +3.00\\
+★ give full plus\\
+♠ Threshold for correction of anisometropia should be lower if the child has strabismus\\
+♦ Defined as >15 degrees from 90 or 180 meridian\\
+  * These values are based on consensus of expert opinion (see AAO source below)
+  * For children 4 years and older: prescriptions should be based on visual acuity measurements and visual functioning when at all possible
+===== School-Aged Children =====
+==== General guidelines: ====
+  - Glasses should be prescribed based on visual acuity testing at distance and near.
+  - An appropriate screening history should include questions about difficulty with near reading vision and distance vision
+==== Myopia: ====
+Prescribe glasses for children with distance vision worse than 20/30
+==== Astigmatism: ====
+Prescribe glasses for children with distance or near vision worse than 20/30
+==== Hyperopia without Esotropia: ====
+  - Prescribe glasses for children with vision worse than 20/30 at near or distance
+  - Prescribing glasses for children with 20/20 vision may be appropriate if vision is worse at near viewing or significant reading difficulty that appears to be related to poor accommodative effort.
+  - Glasses should have less than the full amount of hyperopia.
+    - The amount of under-correction can be based on the amount of hyperopia that improves vision
+    - The amount of under-correction can be from 1 to 3 diopters to help encourage glasses wear.
+==== Hyperopia with Esotropia: ====
+Prescribe full cycloplegic refraction
+==== Anisometropia: ====
+  - Correct the difference between the two eyes to within 1 diopter
+  - If one eye is hyperopic and one is myopic it may be appropriate to undercorrect the hyperopic eye by 0.5 to 1 diopter.
+  - When the child has reached visual maturity, glasses may be discontinued if desired by the family.
