No color or tinting. Explanation: Means "clear", with no color or tinting. -------------------------------------------------- Note added at 2005-01-22 23:25:14 (GMT) -------------------------------------------------- Yes, \"formula\" means \"chemical compound\" or \"mixture\". -------------------------------------------------- Note added at 2005-01-23 00:35:41 (GMT) -------------------------------------------------- So, what you have here is a formula (chemical compound) that you dissolve in water and apply to the lenses to absorb ultraviolet radiation. This keeps the UV from passing through the lenses into your eyes and causing damage. |
