Is there any literature available on how to care for glasses with Anti-Reflection Coatings?
Some lens manufacturers will send out leaflets to optical practices containing advic on ho to care for their lenses so you ask at your local Opticians. The main thing to remember if you have anti-reflective lenses is that they should never be cleaned with soap, washing-up liquid or any other kind of detergent. This can break down the coatings on the lens. Ideally you should use a specialised lens cleaner (available from most optical practices) but be sure to check that it is suitable for anti-reflective lenses. Spray both sides of the lenses and gently rub dry with a lint free cloth. If you don't have lens cleaner, use water. Under a running tap, rub the lenses with your fingers and gently dry with a lint free cloth. Never use your clothes to wipe your lenses. As with all lenses, they will scratch if left lens-down on a surface and you should always keep you glasses in a case to protect them when you're not wearing them.

More expensive lenses usually have more durable construction needed by busy pros and wider / faster apertures (e.g. f:1.4 pro lens maximum aperture vs F:3.5 in consumer lenses).
