As for what is available in the U.S., the list starts off with the Chrysler 200S V6, which is the only car on the list with less than 300 hp. The midsize sedan might be getting the axe soon, but it is one of the most powerful front-drivers available today.
Amblyopia is a childhood problem that happens when one eye is weaker than the other. The brain chooses to take in images from the stronger eye and ignore images from the weaker eye. This means that your child uses the strong eye more than the weak eye. If the weak eye doesn't have to work, it isn't able to develop good vision.
Close one eye and then the other. When you close one eye, the object will be stationary. When you close the other eye, the object should disappear from the hole or jump to one side. If the object does not move when you cover one eye, then that eye is dominant. The eye that sees the object and does not move is the dominant eye.
