Update on contact lenses

In short, I gave up.

In the first post I mentioned that I felt OK with the single vision lenses but that I hadn’t tried driving with them in. As soon as I did, I started to notice problems.

The main one was that I couldn;t focus on vehicles following behind using the internal mirror: it just stayed blurred. The other, more troubling, artifact was dazzling at night and coronas around car lights. The first time out at night I had to pull over and take them out. It was downright dangerous.

After a further consultation it became apparent that I am actually left eye dominant whereas the optician (and I) previously thought I was right eye dominant. That explained the problem with the mirror: the left eye had a distance vision lense. After some discussion, we moved to varifocal toric lenses. However these were monthly’s and took 10 days to obtain.

I really tried to get on with these, but the night vision problems remained and my vision just wasn’t as good as with glasses. Eventually I admitted defeat until something new comes along.

Day One with contact lenses

My close up vision has been deteriorating for about 16-17 years though. I moved over to Varifocals years agoContinue Reading

“Perpetual” motion, maybe?

I know “perpetual” is over egging it, so don't shoot me down. However, this is a fascinating example of how long a well balanced object can oscillate. I've always been fascinated by those instances where simple objects can oscillate for ages with no external input of energy. I've seen it with a bunch of keys;Continue Reading

iPhone 5S? – No thanks

It’s time to get off the continual upgrade treadmill for a while For as long as I’ve had a mobile phone, I’ve always been on a contract. In the past this has been great as it meant that I’ve been entitled to a regular upgrade. However, this entitlement has come at a cost and I’veContinue Reading

Day one on Nokomis

Day one on Nokomis

Adventures on the river For some time now, my brother in law’s friend has been suggesting that Varina and I take Nokomis away for a few days. Nokomis, named after Hiawatha’s grandmother, is a 49 foot narrow boat based on the River Nene near Wellingborough. It used to be a house boat but now sitsContinue Reading

Goodbye Posterous

Well, that was an interesting interlude. As most will be aware, Posterous is closing down at the end of April. As a result, I’m back here for a while. I suspect I won’t be here long as the hosted version of WordPress is too restrictive: I can’t add plugins. However , it will do untilContinue Reading
