Fall Filters

Finally I have some real news to report!  It's been since June 18th that anything has really happened.  Lots of factors contributed to this slowdown on my end and the professionals helping me through this process.  After not hearing a word from Dr. DeCarlo's office in over 4 weeks, I started calling....daily.  She got in touch with my driving instructor, Jennifer.  Jenn left me a voice mail last week to pick a sunny day to drive.  Well after some phone and email chase we finally nailed down today for her to test me as a passenger with the red filters.  The goal was to see how well I could see the red lights and stop signs while using the new filters.

I was wearing a generic fitting pair of red filters, so it was awkward at first.  Jenn made some adjustments to my bioptic and kindly taped them together with the generic red filters.  After we got them all taped together, it was test time.  It was very bright out today, so I was a little apprehensive.  Plus, I'd not worn the red filters but once on June 18th, so I had to get used to them again.  Let me explain more about how the red filters work so you'll know what I mean.

A little background about me: with my regular vision I can't see red "lights' in daylight hours unless I open my eyes extremely wide.  Since one can only do that so long, it's not a suitable long term option.  With my regular vision, red lights during sunny hours appear to be turned off;  aka...black.  The red filters actually make any red light JUMP out at me just by magnifying its vibrant color.  The thing you probably don't realize is red filters, filter OUT green.  So the green lights appear black!  Ok don't freak out yet.  The good news is the filters do NOT cover the tiny hole in my bioptic that is unfiltered.  Therefore:  I can see the green lights just by peeking in my bioptic for a split second.  I can see the red lights by using my normal vision and looking through the red filters.  The red filters also seem to work well making the yellow lights jump out.

Jennifer began asking me what color the lights were.  I was a little confused at first having to kind of think backwards.
1. If the light in my normal vision using red filters appears black: then in reality it is green.  I will see black through my filters and green through my bioptic.
2. If the light in my normal vision using red filters appears to be vibrantly on, then in reality it is red.  I will see vibrant red through my filters and and black through my bioptic.

Now if that makes any kind of sense to you, please pat yourself on the back and grab a energy drink.

I was able to easily distinguish how many tail lights were on a car, when they were blinking, and when they were solid.  The stop signs were a little harder to see with the red filter then just using my regular unfiltered vision through the bioptic.  Jennifer seemed pretty relieved with this new revelation.  She could now feel safer with me. She admitted she was confused, given my old erroneous diagnosis, why I had trouble with the red lights.  Now that Dr. DeCarlo gave me a accurate diagnosis it all makes sense.  Another great thing about these red filters is they wrap around the sides of my face blocking out bright side lights.  This greatly enhances my ability to drive safely during the day.  However, the safest time for me to drive will be night.  I would not need the filters at night and could just use my bioptic.

After riding around for about 30 minutes Jennifer dropped me back off at work.  She told me she would have to now take my bioptic back to the office to make sure the cut of my new permanent red filters is an exact fit to my bioptic.  So with that, I was very pleased with today's progress.  I was also thankful that the journey didn't end before I ever got to get in the drivers seat!  Keep in mind I'm still doing passenger vision testing.  I have not ever touched the car.  Now that I've tested multiple times as a passenger with the bioptics, and we've seemed to conquer my color vision problems on this passenger test, the next step should be to get my permit.  I'll let you know when I get my red filters.  I'm going to send photos on my next post of them so you'll finally see what I'm talking about with your own two eyes.
