“What treatment do you recommend for amblyopic eye?”

Amblyopia has "a window of opportunity" for any improvement to occur. The earlier that amblyopia is diagnosed, a better the may occur. Patching, glasses, and contact lenses are usual therapies. If the amblyopia was a result of an eye turn or strabismus, muscle surgery may help the cosmetic issue.
I would strongly suggest that an eye doctor become involved in order to determine what the actual corrected visual acuity is with the amblyopic eye. And a plan needs to be implemented to determine if any improvement may occur at this time with lenses, patching, surgery, or other combined therapies. One factor to be aware of, there may be a depth perception or binocular vision problem that exists. So safety first, always. In order to protect the "better seeing" eye, safety lenses worn full time should be considered. These lenses are polycarbonate or trivex plastic material.

It’s important to wear her corrective glasses or contacts to ensure that her eye with amblyopia will have the best possible vision. I usually remind patients to buy safety lenses in their glasses to protect the good eye from hazards. Some Optometrists recommend eye patching to work and try to improve the amblyopic eye and the times depend on many factors. There are patching schedules of 30 minutes all the way up to 4 hours per day while watching TV. Discuss those schedules with her optometrist. 

Amlyopia needs to be properly managed by an eyecare professional. If a correction is needed, then glasses need to be prescribed. Patching the better seeing eye can force the weaker eye to work. A vision therapist can evaluate the eye to see if therapy will work to strengthen the eye.

I would seek out a developmental optometrist. Go to covd.org to find a specialist near you.

Depends on the severity, and on the cause. If glasses are needed I would absolutely have her wear full time. Also, though not always successful at that age I would have her try and patch her good eye part time to try and get weaker eye to improve.

I would recommend visiting an optometrist specializing in vision therapy to properly assess the severity of your daughter's amblyopic eye, and possible treatment options.

I recommend an evaluation with a skilled eyecare professional. There are many different causes of Amblyopia, an astute provider could create realistic goals. Without knowing your daughters specific visual needs, I couldn't provide specific advice.

Patching the good eye 4 hours a day, 5 days a week and follow-up in 8 weeks with the eye doctor. Other cases require strabismus surgery.
