Anti-reflective (AR) coating reduces glare and reflections on eyeglass lenses, which can improve clarity during night driving and screen use. It is often worth the extra cost for people who spend time under artificial lights, drive after dark, or want lenses that look nearly invisible in photographs. However, it adds to the price, requires gentler cleaning, and may not be the best choice for very young children, extremely active lifestyles, or tight budgets. An optician or eye care professional can help you match the coating to your daily routines and lens type.
