Actually, no. You'd probably be disappointed to know that what your mother told you about carrots is just an urban legend. Lack of Vitamin A (contained in carrots) can cause poor vision, which can be repaired by adding more Vitamin A to the diet. However, carrots cannot make your normal vision better.

The truth behind their success was actually the discovery of radar technologies.
