Monovision training. and testing
Posted , 4 users are following.
I read a page titled "Monovision: Underestimate at Your Peril". It includes a Youtube video (second one) that aims to teach you to train your brain for monovision. It is titled "how to get the best from Monovision".
My quick take on the process is that you look at something that is at the ideal distance for your far eye. Cover each eye, alternating. This is to teach the brain. Then similarly, look at something ideal for your near eye. Same procedure.
During this training time, avoid looking at things that are at an intermediate distance where each eye sees about as well as the other.
So for those who got monovison, and are wondering if that was a mistake, I think that training method could be useful
I then went back to the first video, titled "how to test for monovision". Interesting. Have any of you ever had a test like that? It sounds very useful. Also, I have never seen one of those computer-controlled lens switchers.
It looked to me as if the patient would accept 1.0 D or 1.5 D monovision, and that 2.0 monovision would be a problem. However this test was done before the patient went through any brain training.

I admit I am in the camp of "just do it". Monovision works with the brain deciding how much of each eye's image to use. I don't think it is a conscious decision. Your brain just learns how to do it by itself. But, perhaps there are cases where the brain does not want to cooperate, and possibly those exercises could be helpful.

Excellent article. Too bad there aren't more cataract surgeons like him.

Thank you Trilemma for your suggestions. I'm having difficulty seeing with my 2nd /left eye cataract surgery after 3 weeks post op. This left eye had LRI Laser procedure for astigmatism, but Dr. says it is healing fine and that now my brain has to adjust. Has anyone had a fuzzy/film over this near eye correction for monovision, and for how long? I am scared that there is something else wrong, as it does not seem to be getting better. My right eye has a Toric Eyhance lens for astigmatism, and for distance, but I can actually see near and intermediate with it....an added bonus.

What was the target for the second eye, and what IOL was used? 3 weeks is not going to be at the fully healed point, but vision should be starting to get good. Have you had a refraction test done on the eye to see where it ended up? Some unfortunately experience early PCO after cataract surgery, and that would be a possibility. However, it should be visible in an eye exam.

Thanks RonAKA...my left/second eye was for near/intermediate, not sure of type of IOL. They did a refraction this past Monday and I think it is 20/30 or 20/25...(I thought the tech mixed up my eyes though). Right eye is doing well. I wondered about the PCO...one question I did not ask. Asked about the lens being centered and if the astigmatism was either under or over corrected (Dr. said those were ok, and astigmatism was in range of where they expect it to be with the LRI procedure). Mine fuzziness seems more affected by light on the left side and my peripheral is still blurry, which Dr. said will get better. I'm hoping that the healing will not take too much longer....a little discouraging though. I just wondered if it has taken anyone else longer and how long??? It is a little frustrating. I've researched and mostly have read that everyone is different, can take longer. Thanks for your comments.

20/30 or 20/25 is not a refraction. It is just a visual acuity measurement - or how good your vision is. A refraction is essentially your eyeglass prescription that you get after you do the "which is better? 1 or 2? Perfect vision for distance is 0.0 D sphere Astigmatism will be measured as cylinder D. That is what you need to know to figure out where you really stand.
.
Normally it takes about 5 weeks for full healing. If push comes to shove, you may want to go to an optometrist and get an independent evaluation of where you are at.

OK, thank you RonAKA, yes they did a refraction for me. I could get prescription for distance to my left eye, to see if it was better for me. Then, Dr. could do Lasik to correct left eye vision to distance, but not sure I want another surgery just yet. My main concern now is the healing in my left/near vision eye. It seemed like there has been a film over it (Dr. said it was okay), When both eyes are open, I am not seeing clearly yet. Sure hope it gets better. Thanks for all your help.

There should be three numbers for each eye. When you get a refraction, you should get those 3 number, whether you write it down or they give you a piece of paper.

The refraction results will tell you if the cause of vision issues are due to the power being off, or if the cause is something else.
