A lot of people who “can see” often only get their eyes checked when they need a driver’s license or when it’s required for work. People generally judge the health of their eyes using the “clarity” of their vision, and this is often very misleading, here’s why:
1. Our vision is subjective, so unless you compare what you see to what someone else sees, you may believe your vision is good, even when it’s not.
2. A lot of vision-threatening eye diseases (Glaucoma for example) slowly take away your vision, without you noticing, and by the time you do, it’s usually too late.
3. Eye strain and headaches may be signs of conditions such as astigmatism and hyperopia (far-sightedness), which may not necessarily affect your vision.
A lot of systemic diseases can also be detected during an eye exam so schedule yours to make sure there’s nothing to worry about.
