I went in recently for a followup from my lasik surgery. It usually takes a few months for your vision to settle following the surgery while the flap heals up. From about week 1, my vision was registering in at 20/15 which is obviously above average and a hell of a lot better than whatever blindness I was previously. A lot of people seem to be confused about what exactly 20/20 means.
Here is a quick explanation:
If you have 20/20 vision, it means that when you stand 20 feet away from the chart you can see what the “normal” human being can see. In other words, your vision is “normal” — most people can see what you see at 20 feet.
If you have 20/40 vision, it means that when you stand 20 feet away from the chart you can see what a normal human can see when standing 40 feet from the chart.
You can also have vision that is better than the norm. A person with 20/10 vision can see at 20 feet what a normal person can see when standing 10 feet away from the chart.
Obviously, I was quite pleased to be free from my contacts and slightly above normal vision. But the last checkup, I got an even better surprise! I tested at 20/10 – which is something that only about 1:1000 people achieve with LASIK. Hells yes! I thank Mr. Glenn Carp at the London Vision Clinic for making this happen! Whoop.
I have also gone on a couple of diving trips and sailing and can say that it has made such an awesome difference in my life to not fiddle with contact lenses. My only regret is that I didn’t do it sooner.
