Mobile device usage temporarily affecting eye sharpness

I'm a huge fan of mobile devices... I've got a Sony PSP, Apple iTouch, and Nintendo DS which were gifts from previous employers and currently use a BlackBerry Bold and an HTC Google G1 phone which I unlocked to use here in Canada. The great thing about devices with built in wireless Internet is how connected you always are to things.

The other night after a busy work day I was at practice, and like many others I'm usually never really disconnected from the office. I was busy reading and writing emails on my phone and noticed when I got back to the line to practice my eye's weren't focusing on the front sights as easily. I didn't think much of it at the time... heck... the same thing can happen from eating really spicy food. Hah.

rest your eyes while shooting... turn the mobile devices off

What I found is that it's not actually the mobile device that causes any blurriness, it's that I'm targetting visual focus to such a small area for prolonged amounts of time. Eyes get tired. So the combination of practice and focusing on a small area (front sight), coming off the line to rest and picking up a phone to focus on a small area puts a huge strain on one's eyes. The actual difference in sharpness is minimal and not quite on par with Guitar Hero vision, but it's enough that it can make it difficult to focus; especially when trying to hit an area smaller than a dime at 30'.

What I have started to do with more discipline while I'm at the range is to turn the phone off. Disconnect. I'm there to shoot 10s not extend my office hours any longer than I need to. I'll need to find someone to send out Tweets during Finals at Nationals on my behalf. ;)

2 weeks until the 2009 BC Handgun Provincials in Campbell River, BC!
