Depth Perception

I am only blind in one eye and have just got a job in a microbiology lab and I have just started training and they are really particular about everything having to be sterile which is understandable and when I was moving some solution into a test tube I missed the edge of the test tube with the pipette and so hit the outside before I then put it in and deposited the solution. My trainer then asked if I had a problem with depth perception and it had never been a problem before but obviously now it is more noticeable and afterwards I just felt really bad and like I could not do the job well enough and I just wanted to leave. Have you ever had this or a similar problem and do u have any advice.
Thanks for any help Rebecca

Re:Depth Perception

Hi i'm Lindsay and i'm blind in my left eye and i have 0 dept perception my advice is similar to the others take it slow and kind of try to line them up the best you can

Re:Depth Perception

Thanks for your replies they have been very helpful. I am starting to get used to performing these tasks and hopefully they become even easier still.

Re:Depth Perception

I too am blind in one eye (left) and have learned to adjust to not having depth perception.
The key word is "adjust". With you being as intelligent and patient as you are, you will do fine. Just take your physical routines slower than your mind is going. In no time at all, you will adjust. I know this sounds kind of weird, but believe me it really does work. Don't get discouraged, you'll do great!

I also have sight only in one eye (left eye). In my case problems with depth perception have caused me to trip over street curbs, overfill and/ or spill cups, crash into poles, etc, etc. A lot of people say that because my right eye is totally blind my left eye will eventually get worse; they call this effect sympathetic or something. But my ophthalmologist says it’s just a myth. Microbiology training sounds very meticulous. You must be an extremely patient person to be interested in it. But things I’ve learned to do to avoid the accidents I’ve just mentioned include: feeling for the rim of a cup with the tips of my fingers and carefully placing the carton of juice on it before I pour, slowing down as I approach a curb, and extending my hand to touch the pole nearby. It’s all about feeling one’s way before proceeding with the task at hand. Maybe you just need time to become familiar with the materials you’re using. Personally, it took me some time to learn how much the cup should be tilted and how far the tip of a carton of juice should be scraped against the rim of the cup before safely pouring. Perhaps you can learn to scrape the tip of the pipette against the rim of the test tube. But then again your trainers are strict about sterilization, aren’t they? Or maybe when you have both pipette and test tube in your hands you can touch both pipette and test tube together but without touching either tip. Only the tips of the materials you’re working with aren’t supposed to be contaminated, right? Then just touch both pipette and test tube together so that you won’t have any problem with poor depth perception. Once you know the position and distance of both objects you can safely pour the solution. I don’t know if these tips will help you at all. But don’t give up yet. Hope this helps you Rebecca.
