It's Like a Donut

I have an astigmatism.  I found this out today.

I've been struggling with distance vision attached with contact lenses for a couple years.  Near vision is no problem, but distance has been legible, but fuzzy.

Today, I got a bit of an explanation, and new contacts.

I was told they were toric lenses.  I asked if that was based off of torus, and she just repeated that they were toric.  It just goes to show that simply because you're a doctor does not mean you've learned everything there is to know about topology (and going by my Chrome spellchecker, neither do the people at Google).

Clarification for those who didn't keep up with three dimensional figures in math, go here.

The lenses are not cut from a sphere, so they have a definite up and down.  When I put them in, while there is no specifically different feel, my distance vision si still fuzzy.  But as I blink and the lenses settle into position, distance clarified.

So my eyes are almost the same prescription, but they require a different bit of toroidal (another word Chrome doesn't recognize) section to fix my sight.

Various Repairs and Maintenance

So a few things have gotten accomplished this week.

Wednesday, the guy from the fireplace company came out and installed the replacement receiver/controller for the gas fireplace.  He got it installed (nice fire and heat; truly a source of infrared radiation), and then I asked him about getting the heat upstairs.  He said that was an optional attachment.  I said that it was the installation of that blower that had caused the problem in the first place.  In talking on speakerphone with the property manager, we found that there is supposed to be a switch somewhere that turns on the fan to pump the air upstairs.  I told him I know where all of the switches are and what they do.  So we'll see what the future holds with that.

Today, I went for an eye exam.  I found out that my eyes haven't changed since the last time I had them checked.  it sure is nice to have some contacts again.  Plus maybe I can get some new glasses.  I'm very careful with the ones I have, but I think these are closing in on 8 years old, so even with great care, there are scratches showing up.

Now my appointment was at 5:30 in Richmond.  Today was also the day for my replacement stereo for my car to arrive via UPS.  Usually they come between 5:00 and 6:00, but on Friday's with traffic and other circumstances they're usually after 6:00.  I got out of the eye appointment right at 6:00, and checked the iPhone app, and saw there hadn't been a delivery attempt yet, so I kept saying all the way home that I wanted him to arrive at 6:30.  Even allowing for the traffic (I used the wonderful frontage road along the Emeryville Mudflats) I got home in 15 minutes.  Then I raced upstairs hoping he wouldn't arrive while I was en route.  And right at 6:30 the doorbell rang.

So tomorrow, I'll go by SoundSource in Oakland, and see if they can do the work, or if they'll have to talk to the insurance company about full compensation.  And if they have to talk to the insurance company, I'll have to wait for them to do the work on Monday.

My Eyes, Let Me Show You Them

Yesterday we got rained out at the excavation. We're ready to backfill after getting all of our confirmation samples coming back below detection levels. However with the rain, the last slot looked like a muddy bath tub. Yesterday we had 6 to 8 inches of water in it. This morning we had about a foot. Hopefully, it will have time to percolate away, and we can get the hole backfilled tomorrow.

So with a free afternoon yesterday, I called to get an eye check-up. They had an opening at 4:00 so, I hurried on over.

I got the exam, and it turned out that my previous exam (at the Costco in Concord) had given me too strong a prescription. By 0.5 (right eye) and 0.75 (left eye) too strong. So today I'm wearing new contacts that are the next generation of silicone called something like Opti-Infinity. They're more gas permeable, and are half the price of he Night & Day I've had for the past two years.

A nice turnout all around.
