The lightly-pigmented irises of blue eyes, in comparison to brown or black eyes, admit far more photons into the eyes. Many SAD sufferers are blue-eyed. (Think Scandinavia!) Because of this sensitivity, you may find that a light therapy dose less than 10,000 lux is fully effective. That simply requires sitting at further distance from a light box rated at 10,000 lux. Photophobia may result primarily from the short-wavelength component of white light, whether outdoors or from fluorescent sources.
Apparatuses Which May Help
It is worth trying inexpensive wrap-around filters to see if they alleviate the problem. For example, NoIR sells an ultraviolet- and blue-blocking filter (www.noir-medical.com/uv_yellow.htm) which, at the 65% rating, maximizes light transmission above the short wavelengths. Another therapeutic alternative is dawn simulation (see //www.cet.org/store/), which is based on low-intensity incrementing light delivered toward the end of sleep. Even then, however, blue-eyed people often need to adjust the light level below that used by their dark-eyed counterparts.
