Do you have a 20/20 vision? When you see things or objects that are 20 feet away from you, then you have a 20/20 vision. However, understand that keeping your eyesight as crisp as when you are younger is difficult. Why? Several risk factors in your environment can affect your eye health.
Apart from having refractive errors, including astigmatism, farsightedness, and nearsightedness, you may suffer from serious vision problems. These problems are often undiagnosed, causing more trouble.
If you are not sure whether you already have a problem with your eyesight, observe the changes in your sight. If you experience any of the following, it is probably time to see your eye doctor.
Difficulty concentrating
Problems in reading comprehension
Having a short attention span
Frequent headaches
Neck strain
Dizziness
Double vision
Poor depth perception
Frequent eye rubbing
Frequent blinking
These problems, if left unaddressed, may lead to a more chronic case that needs urgent medical attention.
