She doesn't need to see an ophthalmologist, who is an M.D. who specializes in eye diseases. You need to find an optometrist, who provides routine eye care and gives you a glasses prescription. He/She will also screen for a medical problem that could be involved and would tell you if you need to see an ophthalmologist. If you don't have vision coverage through insurance, I would call around to find out prices in your area. Places like Costco, Target, JCPenney and Walmart have optometrists working in their stores (although they are separate providers, not employees of those companies); in general, I think they are a little less expensive. Most optometrists are used to seeing a lot of children, and as far as I know, optometrists don't usually specialize in children. None of them would be considered "pediatric" since that is a medical term associated with MDs. I think the greater cost will probably be the glasses themselves, so again, look for coupons or specials to different optical shops. Most of them send their glasses out to labs to be made, so there shouldn't be an issue with quality of manufacture, just perhaps with frame prices if you go to a lower cost center like Walmart or Target. Despite their advertising, I have always found Lens Crafters to be on the expensive side. They carry very few reasonable frames. Age 9 is a common age to see vision changes, so I wouldn't worry too much. BTW, I worked for an ophthalmologist for years, have 3 out of 4 kids who wear glasses and have worn them myself since age 7. One recommendation, pick frames that have springs on the hinges so they bend out as well as in---much less likely to get broken. Good luck! One more thing---eye strain does not cause eye damage or contribute to changes in strength of prescription. It literally just makes your eyes tired and could make them watery or dry. So no worries about time spent reading or watching TV.
