#1813: LugLag

It seems that shining a bright light into someone’s ears can alleviate the symptoms of seasonal affective disorder. There are light sensitive cells inside the head which react to changes in illumination, apparently.

Today’s invention uses this discovery to help overcome jetlag.

A pair of sunglasses has a daylight-frequencies lamp located on each of the legs. These are mounted in earphone-like cans, so that the effects of ambient light level changes can be excluded by positioning the cans over the ears.

The light levels emitted by the lamps are gradually varied during a long flight so that the body is fooled into arriving at the destination already attuned to local time.
