Vision problems after TBI are complicated. There is often more than one cause for your symptoms. Sometimes, the eyes are causing the problem. Other times, brain processing may be the problem. For example,
Apart from that, as nanowires have even higher density than photoreceptors in human retina, the artificial retina can thus receive more light signals and potentially attain a higher image resolution than human retina -- if the back contacts to individual nanowires are made in the future. With different materials used to boost the sensors' sensitivity and spectral range, the artificial eye may also achieve other functions such as night vision.
There’s More To The 3D Print Than The Eye Can See
The working principle of the artificial eye involves an electrochemical process which is adopted from a type of solar cell. In principle, each photo sensor on the artificial retina can serve as a nanoscale solar cell. With further modification, the EC-Eye can be a self-powered image sensor, so there is no need for external power source nor circuitry when used for ocular prosthesis, which will be much more user-friendly as compared with the current technology.
When your eyeball is shaped more like an egg than round, or your cornea or your lens isn't curved just so, light can't focus in the right spot. That can lead to seeing clearly only at certain distances (nearsighted and farsighted) and distorted vision (astigmatism). You can often correct these "refractive errors" with eyeglasses, contact lenses, or minor surgery.
Asymmetry. Each eye is more capable of perceiving detail below our line of sight than above, and their peripheral vision is also much more sensitive in directions away from the nose than towards it. Cameras record images almost perfectly symmetrically.
However, under low-light conditions, our eyes become much more sensitive (presuming that we let them adjust for 30+ minutes). Astrophotographers often estimate this as being near ISO 500-1000; still not as high as digital cameras, but close. On the other hand, cameras have the advantage of being able to take longer exposures to bring out even fainter objects, whereas our eyes don't see additional detail after staring at something for more than about 10-15 seconds.
While there are many other reasons having the discs close to the RPE is helpful, we will only mention one more. Think about someone who is running a marathon. In order to keep muscles in the body working, the runner needs to eat special nutrients or molecules during the race. Rods and cones are similar, but instead of running, they are constantly sending signals. This requires the movement of lots of molecules, which they need to replenish to keep working. Because the RPE is right next to the discs, it can easily help reload photoreceptor cells and discs with the molecules they need to keep sending signals.
I hear you, and I can respect your reasoning, but I don't want JB-Weld anywhere near my camera equipment -- it's very messy stuff that leaves permanent marks. I've never actually used it myself, but I've had to remove stray JB-Weld from more than a few things over the years, and that has never been fun. I have used mechanical fastening methods and even cyanoacrylate glues for homebuilt camera parts, but never JB-Weld.
BTW, even with 3D printing, there's plenty of design-build-measure-repeat cycling to get things perfect. Fortunately, 3D printers are good at rapid prototyping and mistakes are correspondingly cheap to correct in a new part.
Above $2500 cameras tend to become increasingly specialized, making it difficult to select a 'best' option. We case our eye over the options costing more than $2500 but less than $4000, to find the best all-rounder.
Starting a company and starting a brand couldn't have been any better grounding for me personally. I thought if I'm doing it for other people, if I'm any good, I should be able to do it for myself. My brother Raj has a financial systems background, he worked for a company that used to print money in the UK. He was head of financial systems there so he's got a finance background, and I've got more of the creative strategy background so it marries quite well. I leave him to do the numbers and then he leaves me to do the fancy stuff and it works quite nicely.
A lot of the campaigns that I worked on were big budgets, so there would be TV, a hell of a lot of digital advertising, a lot of out of home, some radio. Obviously, things were shifting more digitally, a hell of a lot socially, but a lot of brands now, even the bigger brands most of their budget will be social and digital-based. Especially now in the current climate, it's the power of social and how you can really utilize that and leverage it for your benefit as a brand really.
Kirpal: We did some SurveyMonkey stuff with a lot of my friends within the industry, but also within our design team as well and their friends and so on. A lot of it was looking at what's out there in the market, why they weren't great in terms of the products-there are some very good products, but there are some very bad products as well. A lot of it is looking at what's already there and how we can improve it, then speaking to the consumers to see how they would use it and how we could add certain elements to the product to make it more of an accessory that they would want to carry daily around with them. What makes it a better product for them to use more regularly? So to hydrate more, yes, but also use less single-use plastic because we are adding those bits that they really want and a key to them carrying it more often.
Kirpal: That was purely for sizing because the product is so sculptural, we wanted to see how it would look. It was so quick and simple for us to do it, we thought, why not? Let's check this, let's check the 3D drawings to see how it looks. With the 3D printing, there was no functionality, the cap didn't work for example and the strap for example, didn't come off so it was more the look of it. It was just to say, "Yes, this looks right." When we first did the 3D printing, we could see straight away that the strap was too big. That allowed us to recalibrate, change the sizing, take it in a little bit before we sent everything to the manufacturer. It cut that process further down the line which is what would have just happened. It was almost a sense check with the quick 3D printing more than anything else.
Kirpal: The first one was changing the size of the strap through 3D printing. There was a hell of a lot that changed in the cap, in terms of the way that it would stop at a certain point. It was actually very difficult to get a quarter turn, there's a top panel that drops, so you basically quarter turn the top half of the cap, the top panel drops and you can drink through it. What was happening to start with was an infinite turn, which is pointless.
Kirpal: To give you a bit of background, the first product that we created was with a different manufacturer than the one we have now. We sold out of our range at a certain point, but we were still in the process of moving manufacturing, but we wanted to take our time to get it right and get the right manufacturers on board and get everything spot on. We had a phase of around six or seven months that we were completely offline, and we had people coming to us and saying, "Can we still buy your product?" And retailers saying, "Can we still get your product?" So, "No, I'm really sorry but we don't want to sell that. If you can wait for a few months then we'll bring something new and you'll love it and we'll take it from there."
Kirpal: That was pretty much all through Facebook advertising. I'm self-taught, I do all the social advertising, paid social in house so everything was through Facebook and Instagram in terms of getting your funnels right. Obviously back then it would all be perspective, awareness-based targeting to really get our brand out there. It seemed to work quite well because the initial product launched at a stage where there was less competition in our market. Now there's a lot more competition and there are a lot more people on Facebook trying to get eyeballs and impressions. We had pretty good cut through, some good creative, and a product that was distinct and stood out. All of those things worked really well for us on Facebook and allowed us to pretty effectively and efficiently sell all of our stock within a certain amount of time obviously.
Kirpal: I've always said that a product is king or queen. We focus on our product as much as we can. The quality of it, the look, the aesthetic. Then photograph it, make sure your photography and your images are as high end as it could possibly be, but be distinct, be bold, be different, be better, is our mantra. By doing that, it's easier to get your paid marketing, your earned marketing, and your own channels to work a hell of a lot more effectively and efficiently. Because our brand was more distinct, it was a very different looking product and is very high end in terms of the premium aesthetics, the premium website, and everything that we would do, it allowed us to get awareness and cut through probably more than we should have.
Kirpal: If we're using a carousel ad, which can work really, really well, that's where you show a collection of products that you have on sale. Currently, we have four products, they're all the same product, but in different colors. We display the four in a carousel with color-matched backgrounds and it is really distinct and it works really well. It's minimal, but it creates a good cut through. You get a lot more impressions than a normal one-unit ad so that could work quite well.
So there are apps built in by our developers that allow certain flows and certain elements to the product. I'll be honest, I'm not that techie to remember the name of it. So we could be a lot stronger on our app game, but for us the key for Shopify is it was so great to set up, to design, to make it as bespoke as we wanted to. The back end is super easy to use so that we can look at it daily and update anything. We have a designer and a developer that we use to get things looking as we want it, but it's more the aesthetic at the moment that we've got in a certain place. 2ff7e9595c
