Several products help shift the body clock to wake up early.

Portable light boxes

If you need to seek light when it is dark outside, a portable light box will help. Light boxes shine bright light (around 10,000 lux) that can shift the body clock.


blue-bocker sunglasses

If you need to see clearly (e.g., to drive) when you should be avoiding light, wear blue-blocker sunglasses. They block the blue light that has the strongest effect on the body clock.

Recommended are the pictured Uvex Bandit glasses which effectively block blue light and are inexpensive. Other sunglasses by Cocoon (with amber lenses) fit over prescription frames.
