Some tints are more suitable than others to different situations. A polarised lens for instance will be excellent for looking through the surface of water because it cuts out multiple reflections, however the same lens will largely wipe out a digital display (especially in a car).
We will generally ask you what you will be using them for and advise you what will work best for you. Conventional fashion frames will be the right choice for some people while others will require something with greater protection from peripheral light, such as fishermen and pilots.
As always please ask us if you have any questions or require them for a special purpose.
