Yes it can: If the double vision is seen with either eye closed, then it may be caused by a cataract whicfh is affected by ambient lighting. If the double vision is elimitated with covering either eye then this is true diplopia. In some patients, when the eye turns outward ambient light can cause glare.

It is possible: Double vision is related either to misalignment of the two eyes, where each eye is looking at a slightly different object; or when one eye's vision is partially blocked by a cataract, for example. If you have double vision and are straining to see in dim light, it may cause your eyes to further misalign, temporarily worsening the condition. Bright light may cause the worse double vision also.
