Tunnel Vision

so, when i look at the computer screen,
i can only see a circle about 2 inches in diameter.

this is true.

i have retinitis pigmentosa,
which is the fancy name for tunnel vision.

the rest of my vision is patchy--
that is, i don't know where i can see
and where i can't.
there are blind spots,
and mostly-blind spots.

i smile.

i've had this condition all my life,
but i didn't know it
until three and a half years ago.

i thought everybody saw like i did.

i was so good at compensating,
no one knew.

but there were odd things.

people just thought i had great concentration.

that's how blind spots are.
you think everyone sees just like you do.

but they may see more,
or they may see less.

may our merciful Lord grant us understanding and increased wisdom.
