Seeing - myopia, presbyopia, astigmatism - why can't children get new lenses?

 Seeing is an essential part of being

Being able to see matters. If we can't see, we are unable to take a full part in normal human activities. Replacing our natural lenses with plastic lenses is an amazingly effective way of restoring sight to people with myopia, presbyopia and astigmatism, but it is usually only used when people have cataracts.

I have been short-sighted (myopic) all my life - before my lens replacement, I was measured as being -12 diopters in terms of my myopia, my astigmatism was extreme, and, beyond that, I was able to see things less clearly, and differentiate colours badly, because of my presbyopia (old-age related vision decline) and my cataracts (that were clouding my vision).

This is not a sob-story about me. Many people are in just this position, and, often, when much younger than I was when my lenses were replaced.

When I was very young, my myopia was diagnosed, and I was prescribed the usual thick bottle-bottom lenses. I thought these were a huge improvement.

Later in life, I heard about Lasik, laser surgery to improve vision. So, I went for it. It was one of the most painful experiences of my life. As the laser cut away my eye, I could smell the burning. I was unable to be exposed to any bright lights, without pain, for three days afterwards. It took me several weeks to recover. I still felt pleased, after that, that I had done it, because I thought that my vision was so much better. I still needed glasses to read, and I still couldn't see things as other people saw them, but I didn't know that, so I thought it was a brilliant improvement.

Several years later, my optician examined my eyes, and said that I was developing cataracts. He referred me to a surgeon. This was a major turning point in my life.

The surgeon arranged for an operation to replace my lenses with plastic lenses - not the lenses in my glasses, the lenses in my eyes. I was quite apprehensive about this, because the lasik surgery had been so horribly painful for so long.

I need not have worried. My lens replacement surgery was completely painless - I really mean that, I had no discomfort whatsoever, none at all.

I could not believe the difference! Suddenly, colours were bright and I could see a huge range of colours. I could also see features far away, on the mountain, so clearly that I thought they might be artificial. When I went to the supermarket, for the first time, I could read all the signs, above the aisles, saying what was being sold there - before, I'd thought it was some sort of joke to expect people to read them, unless they were immediately below them, and I wondered why they bothered... Now I could see that the far aisle was for pickles and pasta - it was a revelation!

Yes, I still need reading glasses to see something close up. Yes, years, now, after the operation, the unbelievable brilliance of colour that I saw after my operation has settled down - our brain accommodates to things and they seem less exceptional. Still, my experience of the world is so rich and varied, and clear, compared to what it was during the first fifty years of my life that it continues to amaze me. Just this afternoon, I was looking at a tree at the bottom of the garden, and marvelling at how I could see all the leaves, not a a blur, but as leaves, and I could see the bright blue of the sky and the many different greens of the tree - for most of my life, this has been impossible.

So, with all this wonder, and improvement, what is my point?

Why can't we offer young children, with bad myopia and bad astigmatism, lens replacement? Why should they wait until they are old enough to have cataracts?

If only, as a child, my lenses had been replaced, my life would have been quite different. I'd have found microscopes and telescopes useful instruments - as it was, I wondered why anybody bothered, because, to me, they just offered blurs. I could have seen the beauty of mountains, I might have been able to play sport - I hated rugby and cricket because I could not see the ball. It seem silly to say this, but, when they sneered at me for dropping the ball it was because I only actually saw the ball when it was a metre of so from me, far too late to catch it.

Can't we spare children this diminished perceptions?

Can't we give people with bad eyesight good lenses?

I really think that we should. Contact lenses, glasses, laser-eye-surgery, all seem to offer improvement, b ut, from personal experience, I know they are actually quite useless. The only thing that really works to fix your eyesight is new artificial lenses.

Depression - it's not just feeling bleak

 I've been depressed twice.  By that, I mean diagnosed as clinically depressed, no simply 'feeling bleak'

There's something wrong with the diagnosis of 'depression', because it is so very easy to think that it is the same as 'being depressed' - It is not

The first time I was clinically depressed was back in the 1990's. I was not coping with life, and used the company mental health option to uget an interview with as 'counsellor'. He listened to me for about half an hour, then showed me a picture of the signs of depression, and explained that I fell into all of these, from what I'd said.

So, I went to my GP, and got a prescription for Prozac. The odd thing was that it worked at once, within a week, I was feeling better. SSRIs are not supposed to work that quickly, but the did. It might have been the   placebo effect, but, within three days, I felt better, and started to engage with life.

 I was lucky. I got better, and started to understand the reasons for my depression. Mainly, it was because I'd broken up a relationship

So, I'm an analytical sort  of person. I score quite high on the autism scale, meaning that I analyse things, before feeling them.

Twenty years later, I suffered a few set-backs. My wife was diagnosed with breast cancer, and I spent time with her during her treatment. Her brother dies. My father died. I was stabbed seven times by a burglar. I was suffering severe financial difficulties, and I couldn't see a way out.

What's really peculiar is that, from all of the above, I didn't realise that depression was a likely outcome.

I found that I couldn't do anything. I spent my time in bed.

I started to think about suicide. I looked at sites that sold inert gassed, such a nitrogen, that I knew would establish an easy death. I worked our ways to kill myself - but, at the same time, tried to make a distance, so that the means to kill myself were not immediately to hand. I had to be that, if I killed myself, I was not just on the spur of the moment.

I told GP about these suicidal thoughts, and he referred me to a psychiatrist, who, after a chat, said, a if it was obvious that I was depressed.

I understood, then, what the problem was. I'd managed, over several years, to keep mysense of self under control by going to Amsterdam and having huge doses of psilocybin, in the form of truffles, from magic mushrooms. These helped me centre myself, and resolved the depression completely.

It has still been a struggle. I'm coping today, but I look out for the signs - I mainly sleep around 11 hours a day, which is more than it should be, but, I'm coping, despite that.

What's amazing to me now, that I'm better, is that I still sleep far more than most people. The great thing is that I've not had any thoughts of killing myself for over a year.

It's odd, really, that it should be such a defining thing, but, if you are reading this, please accept that it is. The practical working out of how you are going to take your own life isn't what you think it is - it's not a conclusion, it's a symptom.

Understand that, and you're on the way back to happiness.
