Everything about Lime :

Lime extracts and essential oils are frequently used inperfumes, cleaning products, and aromatherapy. Lime is also used occasionally to enhance vision by many Asian martial artists. It is done by squeezing a drop or two on the inside corner of the eye. An initial stinging sensation is felt but subsides, this should not be done on a daily/routine basis.

Lime juice can be used to make your hair become lighter with sun exposure, however it can make your skin darker with sunlight.
