Eyewear size guide

 

	Lens Width  It indicates the diameter of the lens, that is its amplitude at the maximum point; it is used to understand how big a lens is, and what the effect of the glasses will be once worn. IS an aesthetic and functional parameter: a small diameter (eg 47-49) identifies glasses with small lenses, suitable for small or women's faces, or to contain lenses with high diopters; a larger diameter (e.g. 53-55-59) is instead more suitable for glasses with a masculine cut, for large faces or for eyeglasses of the teardrop type, here you can apply lenses of medium-low diopters for do not let the thickness of the edges stand out too much.
	Bridge Width Indicates the distance between the two lenses; it is a very important parameter, because it defines how the glasses will fit on the nasal septum, if it will be comfortable at the right point, tight or perhaps too big. To understand which value is more suitable for you, take a soft centimeter and place it in the point of your nose where you usually wear your glasses, and measure the upper part (the support surface of the glasses).
	Temple Lenght  Measure an imaginary horizontal line that goes from the frame to the back of the ears; this parameter is important but not absolute, because in the case of slightly short temples you can work on the curvature of the temples to adapt the fit, or vice versa.
	Frame Width  Indicates the overall width of the glasses, including the frame, from temple to temple.
