Reading glasses are one of the most frustrating additions to our wardrobe that you can think of! They are one of the solutions to the only disease that affects 100% of the human population, "presbyopia". And to add insult to injury, that word means "aging vision"! Everyone eventually realizes that they cannot see well when they bring things close to their eyes, and begin to hold objects and reading material further away to see them clearly. The only problem is that, eventually, our arms are not long enough and the print on the page is too small if we hold things too far away.

20/20 vision has always been considered "perfect vision" by most people. And of course we have all heard nearsighted individuals call themselves blind! But it is hard to know what '20/20 vision' means, and we all know that nearsighted people are not truly blind.
The term '20/20 vision' became known as perfect vision because eye doctors used examining rooms, known as 'lanes' that were 20 feet long! If a patient could see normal sized letters at 20 feet, this was perfect vision. If they needed letters that were twice normal size, they had 20/40 vision, meaning that they were still 20 feet from the letters, but someone with perfect vision could stand 40 feet away and still see the letters.
Blindness is defined as 20/200 vision or worse in both eyes WITH corrective lenses or contact lenses. For this reason, as long as they wear their proper correction, nearsighted patients are not truly blind!
