Our eyes are the windows to the soul. We see the world through them. They are precious to us. But, everyone doesn’t see the world the same way.
It would be great if vision were perfect and 20/20 were the only way that you could see but that is not the case. Some people are born with less than perfect vision and need correction to see in 20/20. As we age, visual acuity lessens and we don’t see as well as we used to.
