For the first 47 years of my life I had an excellent vision. I could read a street sign from a block distance; a wall calendar from across the room, etc. But for the past six months my vision went down, and now I have to use glasses with a 1.00 increase in both eyes when reading.
In order to see easier and not having the frame of the glasses bugging me when looking around, I bought the biggest size glasses I could find, so they cover almost to my ears (well, not that much). That way I don’t see the frame and I can just move my eyes to see what’s on the sides, instead of having to move my head (And I got now a pretty cool 70’s look J ).
Then I realized…for most of my life I have been using my peripheral vision together with the central one…two sets of information at the same time to get to know what’s around: The central vision for what I’m working on, and the peripheral to remain aware of my surroundings.
Also, when in need of looking to something that’s within about 150 degrees I use peripheral and, when that’s not enough, just move the eyes slightly without moving the head, in order to save time in acquiring the needed information.
Now that I have to use glasses, if I move just the eyes, the vision jumps from looking through glasses to without glasses, unless such glasses are huge, like goggles (which I haven’t found yet)
All this got me thinking…does the use of prescription glasses have an influence in the way we think?
Let’s suppose for a moment the difference between someone who never used glasses (like me) and someone who always used glasses from a very early age.
The person who never used glasses might be accustomed to move the eye balls more than the person using glasses, who might be accustomed to move the head instead of the eye balls, so to keep the eyes within the surface of the glasses to retain the corrected vision.
Could this mean that someone who never used glasses might be used to get more information of the surroundings, compared to someone who always depended in corrected vision? And because of being accustomed to have more information, requires more of it to make any decision as a normal condition, compared to someone who is used to wear glasses that maybe take decisions based in less information?
When driving, I tend to keep the central vision on what’s immediately in front, and use the peripheral vision to “keep an eye” on the vehicles, streets and pedestrians by the sides. Maybe someone wearing prescription glasses doesn’t have all that information, unless moving the head from side to side all the time. Or simply goes by with less information about the surroundings when making a driving related decision?
Based on this, maybe there is a difference in the decision making process from people who never used prescription glasses to those who always wear them. Maybe those who need prescription glasses from an early age might be able to make faster decisions, since they are accustomed to deal with less information under the same conditions.
