Default Hi-res Amsler Grid - Eye Damage Assessment

A couple weeks ago I got a bit worried about a bizarre spot in my vision. I thought it was a floater but I generated an Amsler grid just to check (no worries - it was just a floater). Since we're a group of eye-safety concerned laserists, I thought I'd share.

I wasn't satisfied with the size of the Amsler grids available online, so I generated a new one. This grid is large enough so that you can hook your computer up to a large HDTV to check your whole field of view if you're concerned.

To use the grid, cover one eye and look at the central dot on the grid.

Below, a normal Amsler grid is on the left. If you have some sort of eye damage, you might see spots on the grid like this, on the right:



Here's an example of what distortion due to retinal damage may look like:



Additionally, parts of the grid may disappear, or the central dot may disappear.

This one is 1920x1080: http://i.imgur.com/XddDqel.png

I wrote a program that generates them if anyone wants a different size or different line spacing.

After viewing the grid, if you think you have retinal damage, you should see a retinal specialist immediately.

Default Re: Hi-res Amsler Grid - Eye Damage Assessment

Thanks, very useful!

I know I have some very minor damage, but it never shows up on these kinds of tests. Even blind spot mapping fails to show it. It is a very small spot (looks to be the size you would see a 2mm^2 round circle at about 2 feet out from your eyes) that only shows up randomly in certain lighting conditions for a split second just after blinking or looking away quickly. It seems to be in my right eye but since I can't reproduce it on command I haven't been able to determine for sure. Had it for years, and I attribute it to a laser show I went to which had crowd scanning, but that is mostly due to my paranoia about it, haha. I don't know when else it could have occurred. It doesn't affect my vision in daily life and seems to have no detriment to mu acuity. I wish there was a simple test that could confirm it though.

Thanks for sharing it.

Recently I have visited an ophthalmologist because my left eye has numerous floaters. The doctor has examine my eye with equipments en the conclusion was the ageing of the eyes. Due age my eye fluid has stiffening up and causes a lot of floaters. This eye fluid was never changed since the birth. Everybody will eventually get this problem. It wasn't cause by the lasers.
The solution is an eye surgery and replace the fluid with clear water but the chance on cataracts will increase on further ageing. That means another surgery to replace the eye lens. Oh well, you can't defeat the nature.

Okay this was a little side story.

As a kid I used to have sniper's sight. Absolute last line on those tests with smaller and smaller letters, no sweat.

Now, need glasses to read what it says on the blackboards/whiteboards.

Still, not *too* bad, I actually don't really wear my goggles all that often, and being shortsighted, I guess it's my body's adaptation to growing roots in front of my computer

AND, it's not damaged in any way, those test in OP is perfectly uniform in all of my focused and peripheral sight.

Does anyone start seeing diamonds after looking at the grid for a while? Like squares from the lines, but rotated 45 degrees? All of the lines are straight, just starting to see diamond patterns after looking at it for a while

Default Re: Hi-res Amsler Grid - Eye Damage Assessment

@hwang21 - Probably just your eyes and brain playing tricks on you.

@Eud, I know the feeling.

My vision was fine up until I was in 6th grade. At which point I started having major problems just being able to see the chalkboard in class. After that it got progressively worse.

Doctors attributed it to the fact that I'm a rather prolific reader, and was even more so while in school. (I read literally whole sections of the middle school library )

Now my eyes are a -7 and -6.25 with some astigmatism thrown in just for fun

Expect your vision to get worse as you age... eye treatments are getting a whole lot better now though. I'm actually seriously considering having eye surgery done next year. If it goes well, I could well end up with perfect, or near perfect vision for 10-15 years before needing glasses again. Even if the correction is not perfect, they should be able to at least erase the astigmatism, which would allow me to wear regular single use contacts. I can wear contacts even now, but they suck for computer work, and due to how they work, they can't work if your head is tilted... which basically limits the use for me strictly to the rare occasion when i do something extra active.

Ouch, that's a whole lot. If you're using the same system as I do, mine was -0.5 when I got glasses but I can see it being worse after a few years now, at about -0.7.

Nothing compared to you but creates minor nuances, such as reading precise time of the train at the train's station displays near platforms. Then I gotta use that box-with-your-fingers trick.
