Brightening your home can brighten your life. In fact, improved lighting can even save you a trip to the eye-doctor. The shorter days of winter require brighter interior lighting to ward off tired eyes and if you're over 30, you may need to amp up the light in your home just to do the same tasks you did when you were younger.
Even though you've gotten a bit older, it's not necessarily true that you need stronger glasses (though a doctor has the last word). Sometimes, the lighting in your home is the problem.
