If you’ve read some of my tweets or my previous post on 3D technology you’ll know I’m not a great fan of the technology. If you want a less biased view on the current 3D tech debate then read my 3D technology: an unbiased view post.
My hatred though is not only because I don’t like the tech but because I feel it is currently being used to cover up the shortage of really good films coming out of Hollywood and is trying to encourage people to the cinema by impressing people by things popping out of them. I can do a more impressive version of this by standing at the front of the cinema and lobbing things into the audience, that’s real 3D!
Right time to lay in to 3D TV. How pointless is watching football in 3D? how much of a 3D effect do you actually get when you go to the football, how far away do you sit? I can tell you the actually 3D effect the eyes get in real life when you are viewing at that distance isn’t much, if any. I don’t need a 3D TV, it’s more expensive upfront, the only real content

Since my first post on 3D cinema the use a 3D technology has begun to creep into daily life in other ways. With electronic companies doing their best to try and get us to embrace 3D Televisions and now Nintendo release their new 3D handheld games console the Nintendo 3DS, there seems to be a major push to try and get us to use and love this new technology. This has prompted some in the optics industry to speak about the new technology and it’s potential effects on their eye, especially as the Nintendo 3DS comes with warning guidelines: players are advised that 3D gameplay causes eye fatigue more quickly than 2D gaming and are told to take a break after 30 minutes of play. Nintendo also says that children under six shouldn’t use the 3D mode at all, since their eyes are still developing, and that parents can use controls built into the 3DS to lock it into 2D mode for children.
The AOP’s (Association of Optometrists) education advisor Karen Sparrow comments about the release of the Nintendo 3DS were published by both the Daily Telegraph (21st Jan 11) and the Guardian online (20th Jan 12)

After seeing Avatar instead of reviewing the movie as that had been done to death already round the web I thought I’d look at 3D cinema, how it works and how you eyes interpret what they are seeing. A month on I’ve now got round to writing the post I meant to ages ago.
3D cinema has been around for a while now but it has been only used in specialized circumstances, now with digital projection and other new technology it is trying to break through into the main stream. Before I get going on how it works, I just want to say I still don’t get the fascination with 3D cinema, I’m not a big fan. Can we not tell a story anymore, do we need to hide behind all the smoke and mirrors of CGI, big special effects? I just feel 3D is just another technology we can use instead of actually making a good film with an interesting plot. I will keep going to the cinema if you make good movies, I don’t care if it’s black and white, 4:3, 12.1 surround sound or whatever, make a good movie and I’ll keep watching. Anyway, enough of my

So it’s been ages since I wrote a post about eyes when I said I would do it regularly, I’m such a bad blogger! I thought I would continue my basic introduction to eye conditions, so after my basic guide to what a cataract is I’ll try and give you the basics of Glaucoma.
Glaucoma is quite a big topic and it can give complicated very quickly. There are a quite a few different forms of the condition, but in simple terms Glaucoma is damage to the optic nerve head (this is the the point at which the connect between the eye and brain joins the eye). The damage is usual caused by raised pressure within the eye (which is not the same as raised blood pressure). If you think of the eye like a football (bear with me), if you pump a football up too much then the pressure causes the stitching to be put under tension, instead of the the stitching (which your eye doesn’t have!!) in the eye the tension is put on the optic nerve head and if this happens for a long time it causes damage.
The pressure in the eye is controlled by a

I have to tell a lot of people they have cataract and I usually get asked quite a few questions about them, so I thought I’d give a little information about what they actually are. Starting with the basic definition. A cataract is a natural clouding of the lens within the eye.
What is the lens?
Well firstly the lens (or crystalline lens as it is actually called) is with in the eye, it sits behind the iris (the coloured bit of the eye). You can’t actually see the lens but if you have a quick stare into someones eyes you will see the iris and in the centre of that a what looks like a black hole, this is the pupil. The lens sits just behind this.
Will I be able to see a cataract?
Normally you can’t see a cataract with the naked eye except when it gets really dense and turns white, usually these days it is operated on miles before it gets to this point. A lot of people still think a cataract is a skin that grows over the eye, this is not the case, as you now know (if you didn’t already) the lens

Colour deficiency is what people call ‘Colour blindness’ incorrectly. The reason it is called a deficiency and not blindness is because you can see the colours but just have problems distinguishing between some, basically colours that look different to people with normal vision are confused by people with a colour deficiency. There are two main types of deficiency, these are acquired and congenital defects. Acquired defects are as a result of a disease or drug induced where as a congenital defect is a hereditary defect that someone is born with and doesn’t get worse.
A quick look at the anatomy of the eye will help understand how we see colours and what can go wrong. I’m just gonna keep it really simple. The human retina is like the film in a camera, it is where the image that the eye ‘sees’ is formed. This image is then converted to messages and sent of to the brain to be interpreted. The retina is packed full of millions of light sensitive cells, these are called photoreceptors. There are two types of photoreceptors called Rods and Cones. Rods cells are used in low light levels, the clarity of vision these cells produce is

I just wanted to pass comment about the technical aspect of two films I’ve seen recently, the two films I’m talking about are ‘Valkryie’ and ‘Seven Pounds’, just so you know there will be some spoilers in this post, so don’t read on if you don’t want to know what either film is about. I say spoilers, I’m not sure I could spoil ‘Seven pounds’ I wasn’t a great fan of it.
What’s my gripe with both films, well, it’s got nothing to do with their subject matter or what I thought of them. It’s to do with eyes, yes those two things on the front of your face you use to see. I spend a fair bit of time looking at eyes in my job so I think I know a little about them. On to my complains…..
Firstly, I had a major problem with the end of ‘Seven pounds’. At the beginning of the film we see Ezra Turner (Woody Harrelson) he obviously has something wrong with his eyes, more specifically it looks like the cornea, not sure exactly what he’s supposed to have but the front looks white (should be clear) so I’m guessing some corneal scarring,
