Ultraviolet light. Light therapy boxes should be designed to filter out harmful ultraviolet (UV) light, but some may not filter it all out. UV light can cause skin and eye damage.

The reason behind it has to do with the pretty, little planet called Venus. She will be entering her rare retrograde phase on July 25 th, 2015. Astrologically, a Venus Retrograde period is one of the most important times for matters of love. It happens every 18 months to two years and every time Venus does her backwards dance, relationships end up being the topic on everyoneâs minds. Karma also plays into this period, which makes it all the more special.
At an obliquity of zero, these lines point in the same direction i.e. the rotational axis is perpendicular to the orbital plane. Axial tilt differs from inclination. Because the planet Venus has an axial tilt of 177Â° its rotation can be considered retrograde, opposite that of most of the other planets.arth 's orbital plane is known as the ecliptic plane, and Earth's tilt is known to astronomers as the obliquity of the ecliptic, being the angle between the ecliptic and the celestial equator on the celestial sphere. It is denoted by the Greek letter Îµ. Earth currently has an axial tilt of about 23.4Â°.
