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.
Most people have a dominant eye, or one eye that works a little bit harder than the other. Even though you use both eyes to look at an object, you use your dominant eye more. Eye dominance is important for certain sports which require accurate aim. If you are considering monovision correction to reduce the need for reading glasses or bifocals, your eye dominance will need to be considered.
