Before buying a pair of sunglasses, it is important to know some technical terms of the different components. The various parts that make up the anatomy of your sunglasses influence the way they adapt to your face. Bridge – It is the part between the lenses of the sunglasses that passes over the nose and supports the weight of the frame. It plays a significant role in determining the fit of the frame. Nose pads – These are the two plastic bits attached to the inside of the frame. Even though they are the smallest visible component of your sunglasses, they are important for keeping them in place and ensuring the right level of comfort. In quality models it is possible to adjust them to guarantee a perfect fit. Frame – The frame “frames” the lenses and is the first thing you look for when choosing a pair of sunglasses, because it determines your visual style. Temples – The temples of the sunglasses run along the sides of the face and are fixed above the ears. They keep the glasses in place. The end of the temples, i.e. the temple tips in contact with the ears, guarantee comfort and relieve the pressure of the sunglasses resting on the upper part of the ears. They also prevent sunglasses from falling by keeping them in the correct position. Hinges – These small mechanisms do a lot to ensure maximum comfort in the fit of your sunglasses. They connect the ends of the temples and allow you to widen them according to the size of the face and to bend the temples inwards when the glasses are not used.
