LENS: TINTS
As you will have noticed light is transmitted through the lens of a pair of sunglasses. The amount of light that a specific lens allows
to pass through it is called its transmission ability.
In the previous section you learned that lenses can be specially coated to influence the amount of light that passes through them,
ranging from a mirror coating which reflects some of the light hitting it, to a gradient lens which allows differing amounts of light
to pass through, to a fully polarised coating which blocks out the glare. You also learned about photochromatic lenses which adjust
to light conditions, becoming darker in bright conditions and lighter in dull or overcast conditions.
The underlying principle we can observe in all of these examples is that the colour of the lens influences the extent to which it
allows light to pass through it and the associated quality of visual acuity. Sunglass designers have tapped into this knowledge and
now offer you and your customers a whole range of tints to choose from.
While each of the colours offers unique functional benefits which we will outline for you, collectively they also allow the
fashionistas to have lots of fun colour coordinating their sunglasses to match their fashion selections each season.
The table below highlights the functional features and applications of each of the tints or colours. Get to know these well so that
you can guide your customer on what’s best for his/her specific functional requirements.
