Just one more word...
Anti-reflection always consists of a hard coating & anti-reflection. Actually, you can clearly see whether or not your sunglasses have anti-reflective lenses. Anti-reflection always leaves reflex; the reflex is the soft color that covers your lenses.
If your coating breaks down, the problem is always the hard coating. It can crack or chip. optoVision can give you a 3-year warranty, because we have very few coating problems. There is a separate hardening liquid for each type of index (1.5; 1.6;...). The liquid that is made especially for index 1.5 lenses will not be absorbed as well in index 1.6 lenses or higher. However, many manufacturers follow this rule to keep costs down. That can result in premature cracks in your coating. optoVision gives you the guarantee that we will make 1.5 hardening fluid for 1.5 indexes, 1.6 fluid for 1.6 index and so forth.
All coatings are available for single-vision and multifocal lenses. Would you like to learn more about these lenses? Go to the single-vision and/or progressive lens section to see the difference between the various types of single-vision and multifocal lenses.
