Plastic
An almost limitless range of plastic colour are available as single colour, graduated colour or rainbow (multi-colour) tints.

Polycarbonate
Dark brown and dark grey sunglass tints are now available for polycarbonate lenses. They are applied using Silint's vacuum coating skills to provided the ultimate, light-weight sunglass lens.

Glass
Siltint has 8 standard glass colour coatings, 9 special colour coatings and 5 graduated coatings in brown and grey. Rainbow and colour combinations are available. As glass colour coatings are applied in high vacuum to a fixed and specific control pattern governing the machine cycle, it is not possible to provide 'in-between' shades, as is possible in plastic tints.
