      My glasses and contacts correct this. If I look at my rifle sight without, the dot is a star. With correction, perfect dot.

        For some people with mild astigmatism the coating can help as it reduces the glare enough to make it manageable.

        However astigmatism is when the eyeball itself is misshapen. More like a barrel than a sphere. If it’s bad enough then anti glare won’t help even with the correct prescription. Then toric contacts, implants or laser correction is needed. The best solution depends on how bad it is and what is the person’s primary aim. Freedom from glasses, rock solid distance viewing or something else
