In the Star Wars D20 books says the following about it:

Miraluka are blind to all wavelengths of light. However, their ability to see through the Force allows them to sense their surroundings as though they could see normally, allowing them to attack and make skill checks without suffering penalties for blindness.
And the see force check says the following:
See Force detects the relative strength of the Force in a place or person, or reveals the presence of other Force-Users. Your See Force check is opposed by the Force Stealth check of another Force-User. If there is someone or something to detect, you spot a glowing line for energy in the Force, more brilliant than the presence of non-Force-users, and mentally follow it to its source.
You can use this skill on a specific target within your sphere of influence (a radius in meters equal to 100 x your Force-user level). On a successful check, the GM reveals whether or not the target is a Force-user (if the target has the Force-Sensitive feat, the target is a Force-user) and, if so, the relative strength of the target’s Force-using ability compared to your own. (If the target has more levels in Force-using classes than you do, the target is more powerful than you are.) You don’t have to be able to see your target, but you should have a general idea that someone’s there. (For instance, you could use See Force on an enemy pilot, even if you couldn’t see him, as long as he was within range.)
You can also use See Force to examine currents and emanations in the Force to reveal the presence of other Force-users within your sphere of influence (which is 100 meters x your Force-user level). Darth Vader used this application to sense Obi-Wan Kenobi on the Death Star in A New Hope.
If there is no Force Stealth check to oppose your See Force check, the DC is 25 minus the Force-user level of the target that could be sensed (you sense the closest target with the first check, and subsequent checks reveal other targets, if there are any, ranging out from there).
