Hi all,
I am currently using a light projector for testing vision and doing refractions.
I am thinking of using digital eye testing chart with a LCD monitor.
Anyone using digital eye testing chart? Can you share your experience with these charts? Which is a good software and how much do they cost?
Thanks
Microsoft PowerPoint. You should be able to buy a copy in Singapore for about a buck. You can make multilingual charts, graphics, Landoldt Rings or whatever and scale the letters for any length lane. You can also play around with contrast or whatever other parameter suits your fancy.
How do you deal with flipping from screen to screen? Do you basically just use an "up" and a "down" key on a remote?
Hyperlink from a menu.
Interesting, r u doing that?Quote:

There is no link. Can you please send the link via pm?
No, I am not doing that any longer. I am retired and spend most of my time fishing, hunting and traveling about. I suppose that I could make up a pps and send it to you but I feel that I would be doing you a disservice. You should really add to your skill set and do it yourself. It’s not much of a challenge.
It was much of a challenge for me. I couldn't get it done right. The doctor is picky, so we bought a commercial version. One of the best investments made. Worth it for the Wow effect alone.Quote:

I have searched the web. In the US i believed most people use Acuity Pro, and the Smart System. In the UK, they have Test Chart 2000.
As there are no distributors in Singapore for the above softwares, i am concerned about the servicing of the product if anything happened.
For these software, do you pay a 1 time license or yearly license?
Also, if your computer were to crash and needs the software to be re installed, do you need to buy a new software or pay additional license?
Hope anyone who has experience with computerized test chart can share your experience 9in using these software) as I am thinking of getting one of those software for my consulting room.
Thanks. :cheers:

We use AcuityPro. One-time payment. No yearly fees. It runs from a USB "key". Once, a computer was stolen and we had to repurchase. But if your computer crashes, there would be no extra cost.Quote:

We have an 19" LCD monitor hooked up to the computer (a dual monitor video card is installed) that is mounted on the back wall behind and to the right of the patientat about 5'6" high. AcuityPro will automatically invert for a folded room. You measure the distance and AcuityPro will tell you how large to make the letters in the program. I wouldn't recommend anything smaller than a 17" monitor. It has a little cartoon for kids. You can load educational videos to play for the patients. I can't remember the price, but we will be ordering another one next week.
Hi thanks for the info. I guess you can load the program into as many PC as you like but you can only operate one at a time becuase you need to use the USB key. Can you purchase additional USB key or that will be an entirely new purchase with the software package?Quote:

I'm not sure what the cost is, but Eyecuity has a wonderful setup. Can be used with your own PC or without. Hope that helps.

I use Sharp System visual acuity software.
This is software I developed. Free updates & support for life! Version 3 is about to be released...here is more info.
Check out Precision Vision Visual Acuity (PVVAT) software. I have compared Acuity Pro to Precision Vision Visual Acuity software and can tell you from personal experience that there is no comparison. For $200 more, you get a vastly superior product compared to Acuity Pro. Even though PVVAT was developed only 2 years back, it is way ahead in functionality compared to Acuity Pro. Good Luck!Quote:

Patients love it. I go from testing to education with a single computer program. I understand that a new version will be released soon, and that it will have SEVERAL great new features. I expect that the price will increase with the new version.
I don't know the exact cost of the sharp and Thanks for the posting....

Do Digital Eye charts allow for a smaller exam room?
Well, you can go for Digital Optometry’s Spectrum if you like. They offer widest variety of opto-types, chart layouts and new features such as Randomization, Duochrome, Wide Spacing, Onscreen pointers, Wheelchair Button. You can get the Duochrome screens with some unique innovative balancing techniques. You just can install this in your PC or laptop and use.
You can simply pay $ 70 for 14 day trial license and check before you buy the advanced version. If you are willing to buy a yearly license, you will have to pay around 600 dollars and for an unlimited version you will have to spend around 1850 dollars I guess. It is available in Asia (You live in Singapore if I’m not mistaken) and they will b able to help you via their 24hrs contact center assistance.
Before buying any software, read the REAL customer reviews and feed backs. It is important to know about the product properly before you spend a few hundred dollars.
I don't like dealing with companies that have no phone numbers, especially when it comes to support. Free support? Maybe, but how soon, and it's all via e-mail?Quote:

Duh.. I answered a post from 2 years ago. Hate it when I do that.
No...I did because I'm in the market for more software. I bought some today, I'll let you know how it works. (Much cheaper than Sharp systems)Quote:

I'll be setting it up on a Raspberry Pi with a usb remote. Expect it to cost $250 with monitor, mount, cables, remote.
I'll write back once I have it tested.
Most modern televisions - especially large screen televisions - have a USB port. These are typically used for firmware updates. However, it is also possible to place images on to USB drives and have them play on the television. For example, on my very inexpensive LCD TV, I have to change the TV's 'Source' to 'USB' - then I can browse the images on the USB drive using the remote control.Quote:

Did you manage to setup the snellen software? i wanted to try , but did not have a chance ...need to download a copy of linux...i wanted to do it on VMWARE... if u setup...can u tell me other than snellen chart...what other features is in that software other than snellen chart...Quote:

Lots of goodies.
Visual acuity is indeed measured by a Snellen chart, but you have to run a few patients to see what other things would help.
My setup is programmable, so I can show a series of charts in a certain order.
There are "line isolation" options, as well as "letter isolation" options.
There are refracting aids, as well, such as polarized projection (not on an LCD screen, of course) to be used in conjunction with polarized lenses in the phoroptor for special tests, etc.
It's more involved than...meets the eye!

Neat! Make some money.
Had some software installation problems and didn't finish it yet.
Haven't given up, but other things are taking priority.
Should be able to easily image when done, and will post a download link at that time
If you are wicked smaaht you can create anything you may want with Microsoft PowerPoint; Snellen, illiterate E's, Landolt Rings, whatever.
In fact, you really don't really have to be too smaaht. I did this back in the late eighties with PowerPoint v2.
Did you try doing this? I have a similar reqirement and I want to achieve this using android tv box.Quote:
