Our old projection charts were not cutting it.  The optotypes were no longer clear, and they didn’t look good. We had to do something.
So we updated a few of them, but each new digital iMac visual acuity chart was costing us between $2,400-$2,700–and we needed five more!

Instead of simply shelling out the cash, I did a little research and found we could get the same updated technology for less. What I discovered saved us thousands.
Here are the steps to upgrade to new digital charts for under $1,000:

Steps

1. Buy a Mac mini – This will cost you $499 plus tax. It works great and will serve its purpose for years to come.
2. Buy a wireless keyboard and mouse – This does not come with the Mac mini but you are still way ahead.  This will run approximately $70 per item. Your total for keyboard and mouse should be no more than $140 plus tax.
3. Buy the Visual Acuity app from the app store –  Search “visual acuity” and you will find the Visual Acuity app under Medical for $99.99.
4. Buy a monitor – This will range from $100 to $250 depending on the model that you choose. We used old Dell flat panel monitors that we already had and they have been great. If you run HDMI you will need a 6-foot cord, which will cost about $15. If the monitor is older and has VGA, you will need a $29 adapter (example here)
5. Buy a monitor wall mount – One can be purchased from Amazon. $15-$30 plus tax. We bought three of these and they work great. (example here)
6. Put it all together and calibrate the chart (app steps you through calibration – very easy)

TOTAL cost for digital acuity chart – $940

If you are still using the old projector charts please try this test:  stand about 40 cm away from a projector chart and a digital chart on a monitor. Notice the difference, it’s huge.
If you have been trying to convince the rest of your ODs to upgrade to digital visual acuity charts, you now have a budget-friendly solution to acquire the new technology.

If you’re frustrated with the rising costs of information technology and budgets that continue to increase while your net decreases, start looking for ways to minimize costs. Many times a little research and some time can save you thousands of dollars. I am hoping this post will save you money like it did us.
