Easements

Our neighbours a few years ago built an extension above their garage. The garage is directly on the border (not within their boundary). The extension has cut off natural light to the bathroom and kitchen. We naively did not object at the time as we simply did not consider the ramifications to us of the extension being built. For example, we now have to turn on lights during daytime hours when in the aforementioned rooms. This is both an inconvenience, an added cost and has a detrimental effect on the price of the property. Is there any way we can remedy this problem? Thank you.
