Nose guards for glasses are important because they help enhance comfort and protect the nose from injuries. Nose guards often keep the weight of the glasses on the nose, notes the Perfect Eyeglasses Guide.
Nose guards for glasses can be made from various types of materials including rubber, silicone, plastic and glass. They generally help in making the lower edge of the glasses soft and comfortable. They may also guard against injury in case the wearer is involved in an accident. They are available in different shapes including round, oval and elongated, notes the Perfect Eyeglasses Guide.
