The size shown on all products in our catalog is the horizontal extent or width, in millimeters, of each of the lenses, as seen in the following scheme (for "lens").
There is no right size is a matter of personal taste. Everyone has their preferences and style of their glasses as they should be or feel comfortable with them. In addition, many models are manufactured in only one size (UNIQUE). Having said that, we present the criteria used in the standard choice.
In OnlyLens we recommend the choice of the medium size, that is closest to the height 57.5 mm, taking into account the normal lens widths are between 45mm and 70mm. But it depends on your face dimensions and shape and of course on your personal preferences.
There are two factors involved in choosing the size of a sunglasses:
- Shape of face
- Head size
Therefore, for a face or head size more appropriate one size larger and a smaller size stylized faces.
What sunglasses shape to choose
The best size of sunglasses for each face shape can vary depending on personal preference, but generally speaking, there are some guidelines that can help you choose the right size of sunglasses for your face shape.
For round face shapes, it is best to choose sunglasses that are wider than the broadest part of the face, such as square or rectangular frames. These frames will help to elongate the face and make it appear more balanced.
For square face shapes, it is best to choose sunglasses that are slightly wider than the face, such as rounded or oval frames. These frames will help to soften the angles of the face and create a more balanced look.
For oblong face shapes, which are considered the most balanced and versatile face shape, any size of sunglasses can typically look good. However, it is best to avoid sunglasses that are too small, as they can make the face appear too small, and to avoid sunglasses that are too large, as they can overpower the face.
For triangle face shapes, it is best to choose sunglasses that are slightly wider than the face, such as rounded or oval frames. These frames will help to balance out the narrow chin and forehead and create a more balanced look.
Ultimately, the best size of sunglasses for you will depend on your personal style and the shape of your face. It is always a good idea to try on a few different sizes and styles of sunglasses before making a purchase to ensure that you find a pair that you love and that looks great on you.
