Which lenses’ shape is right for you: toric lenses.

Snow goggles come in all shapes and sizes, but lenses only ever come in three shapes.

ylindrical, spherical, or toric: what are the differences between these lenses’ shapes, and what is the best one for you?

Toric lenses are a mix between spherical and cylindrical. The lens is curved both horizontally and vertically, but with two different radiuses. The horizontal curvature is higher to follow the shape of the face, while the vertical one is lower to avoid some of the limitations spherical lenses have.

Field of view: 
Toric lenses really allow to have huge fields of view because they can mix the high horizontal curvature with a slight vertical one, providing great performance both vertically and horizontally. 
Yet, the shape of the lens is only one of the many components that influence the field of view, like the pantoscopic angle or, obviously, the frame construction.

Ventilation: 
Toric lenses are great for ventilation as they tend to leave a more constant space at the bottom around the nose and at the top of the forehead so they usually offer good ventilation.

Optical clarity: 
High-quality lenses are “optically corrected,” which means that the lens’ thickness is calibrated to eliminate or avoid distortions. 
Plus, lenses work best when the light passes through them perpendicularly, so in toric lenses, if corrected, the optical clarity is great.

The shape of the lens is an important component to consider when getting new goggles, but it is only a component. 
It’s always important, when choosing, to try them on to see if, apart from the lens shape, you like what you see.
