The good news: The most common diseases - age-related macular degeneration (ARMD), cataracts, glaucoma, and dry eye disease - are all preventable to some extent.
白内障：一种晶状体变得越来越混浊的眼病，导致视力受损，并最终导致失明；
Cataract: an eye disease where the lens becomes increasingly opaque, resulting in impaired vision and eventual blindness;
如果可能的话，最好能在决定是否行白内障手术之前对这些眼病进行适当的评估及治疗。
