Not enough information is given but my mom is in the medical feild and she says that a condition common with age is presbyopia. It causes the leanses in your eye to become less flexable and less able to thicken therefore less able to focus on near by objects. Another is catteracts which I assume you already know about so I will not explain.
The lens of your eye also hardens with age, which can lead to age-related farsightedness, called presbyopia. As the lens becomes more rigid, focusing on the retina directly is more difficult. This leads to blurred vision and trouble seeing things clearly close up

When a person faints it's usually temporary & the person can be revived within minutes.Somrone who is unconscious won't respond to attempts to revive him.
