The duration of the anti-reflective treatment on eyeglass lenses depends on various factors, but in general, the treatment can last from 1 to 3 years.
Here are some factors that influence the duration:
Care and maintenance: The duration of the treatment is significantly influenced by the care you give your glasses. Cleaning them regularly with suitable products and cloths, avoiding abrasive detergents and rough surfaces, helps maintain the effectiveness of the treatment.
Daily Use: Heavy and frequent use of glasses can cause the anti-reflective coating to wear out more quickly. Exposure to factors such as sun, humidity and chemicals can affect the lifespan.
Lens Quality: High-quality anti-reflective coated lenses often include additional protective layers that can extend the life of the coating.
Frame Type: Some frames can put pressure or friction on the lenses, affecting the life of the anti-reflective coating.
