Vanity light mirrors are generally larger in size, covering greater areas allowing you to see more. Often unframed mirrors hang in your bathroom or another location in your house with adequate lighting above or to the sides of the mirror so as to evenly spread light and give a much smoother, more even look.
Many mirrors are available to suit environment and atmosphere when it comes to bedroom mirrors and many styles and sizes can be found to fit most any bathroom imaginable. The choice of mount and style of lighting can affect and in turn be used to achieve an attractive compliment to any room. Vanity mirrors should be set appropriately to where you will be using them.
Desk Mirrors mounted on top are useful because they allow you to sit and rest, while wall mounted mirrors should be at eye level so that you're not contorting yourself to see into them.
Be sure when selecting a vanity mirror that the room it's in will be well lit and, in the least, that there is enough room to set up lights to make you more visible. You shouldn't have to strain your eyes looking for yourself in the mirror so it is important to light yourself and the area around your vanity mirrors so that there is an evenly distributed coverage of light.
