How long does the hydrophobic layer of the Anti reflection last, the effectiveness of the coating? Does it differ from brand to brand based on the lens coating technology? I would generally assume at least one year.

Properly fabricated (shape, size, thickness, etc.), low chemical environment, no high heat, proper cleaning/very good care...four to five years on average for the best coatings.Originally Posted by Opticia_n
