Loss of focus is a natural part of the aging process when it comes to the eyes and is generally not cause for concern (via University of Utah Health). Over time, the lens of our eyeball loses flexibility, making it difficult to focus on objects at close range (via UCI Health). This is a health condition known as presbyopia, which is so common that most people need reading glasses after their mid-40s or 50s.

注意力不集中是眼睛老化过程的一个自然部分，通常不会引起关注。随着时间的推移，我们眼球的晶状体失去了灵活性，使得近距离的物体很难聚焦。这是一种被称为老花眼的健康状况，这种现象非常普遍，以至于大多数人在四五十岁以后都需要戴老花镜。

Additionally, as we age, our eyes often don't stay as hydrated as they once were. Stress, sunlight, and wind are just a few of many things that can place wear on the eye, causing them to progressively dry out (via UCI Health). Without being able to produce as many tears as we once did, burning or stinging sensations are not uncommon for those over the age of 50.

此外，随着年龄的增长，我们的眼睛往往不像以前那样保持水分充足。压力、阳光和风只是导致眼睛逐渐干涸的众多因素中的一小部分。由于不能像我们曾经那样流下那么多的眼泪，50岁以上的人会有灼热或刺痛的感觉并不少见。

As you approach your 60s, it's also not uncommon to experience "floaters." Experts say these floating flecks are a result of the gradual breaking down of fluid behind the lens of the eye (via UCI Health). However, should you experience additional symptoms such as flashes of light, be sure to seek prompt medical care from an eye doctor.

当你接近60岁时，“飞蚊症”也很常见。专家表示，这些漂浮的斑点是眼球晶状体后液体逐渐分解的结果。然而，如果您遇到其他症状，如闪光，一定要立即寻求眼科医生的医疗照顾。

While there are many changes your eyes may undergo as you age, experts at the University of Utah stress the importance of getting regular eye exams so you can be sure your eyes are operating just as they should be.

随着年龄的增长，你的眼睛可能会发生很多变化，犹他大学的专家强调定期检查眼睛的重要性，以确保你的眼睛可以正常工作。
