清洁眼镜的最佳方式

Reflecting on the Problem

涂层问题

Lenses typically have some form of protective coating and should never come into contact with ammonia, bleach, vinegar or window cleaner. 'Those chemicals can break down the coating or just strip them,' says Dr. Geist. 'You know those bubbles you sometimes see on your lens? Those are caused by 'cleansing' solutions.' Avoid the problem by requesting anti-glare and UV coatings that are embedded within the lens, which can cost about $100 more than regular-coated lenses.

镜片通常有某种形式的防护涂层，因此不应接触氨、漂白剂、醋和窗户清洁剂。盖斯特博士说：“这些化学物质会破坏或者洗掉涂层。你知道有时在镜片上看到的泡泡印是怎么回事吗？那就是用‘清洁剂’导致的。”要求在镜片中加入防眩光和紫外线涂层可以避免这个问题，这种镜片的价格比普通涂层镜片高出约100美元。

Clean Lines

清洁产品

Natural oils from your hands, eyelashes and face can lead to a lot of buildup each day, reducing lenses' effectiveness. Leaving spectacles on a sink or vanity, where hair spray and perfume can fly through the air, adds to the residue. The AOA recommends washing glasses every morning, paying special attention to the frames and earpieces, where hair product and makeup tend to rub off. Whatever you do, don't use the most handy form of water to clean your lenses. 'Some people use spit, but don't,' urges Dr. Geist. Though dirty glasses won't cause an eye infection, saliva 'is not the best hygiene method, and it just won't work very well,' she says. Soap, warm water and a dry cloth are all you need, once a day, to keep glasses optimally clean and functional. 'I have had patients who say they can't see well, but it turns out it is just the scratches,' says Dr. Geist.
