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.
And if one eye is covered by a blue filter, and the other eyes is covered by the red filter, the healthy person sees both colors simultaneously and separately. The left eye sees 20% of the image, and the right eye sees 80% of the image. With age, these rhythms get broken.
