If you resonate with any of the 10 CVI characteristics, you should meet with your ophthalmologist. It's still an unfamiliar condition for many medical professionals, so I'd recommend taking
$1article with you.
I'd also recommended contacting PCVIS on their website (it's the website I linked above) to see if they can connect you with someone who performs CVI Ranges.
Typically it's an eval done by teachers of the Visually Impaired in schools, so finding it in a different setting may be tricky. If you're in TX I may be able to help connect you with a resource for an eval. There's been some drama in my field and so I'm unable to locate the list of nationally endorsed professionals who perform the CVI Range outside of schools.
If you're unable to find an evaluator, it's not the end of the world. As an adult you can read more about it and adapt your life as needed. Most CVI accommodations are pretty straight forward.
I'd highly recommend reading the PCVIS website and about Dr. Roman Lantzy. CVI Scotland and Texas School for the Blind and Visually Impaired are great resources as well.
Paths to Literacy has all kinds of ideas for adaptations. Theory give you an idea on how to adapt your daily life a bit.
Overall, I'd recommend keeping your visual work space clear and uncluttered. Solid, dark backgrounds, few distractions, and use brightly colored tape on colors that stick out to you to anchor your vision on areas in your home and life you need to be able to find.
Try looking at 1-10 items at a time on a solid background. At what point do you Visually lose your target? If you can do up to ten, try up to 20.
Now do it all Again on a busy background like an obnoxiously floral bedspread, beach towel, or the stupid patterned bowling shirt your uncle likes to wear.
Try getting a table lamp to provide a spotlight to hold your focus, especially when you're tired or your eyes hurt. It may help to turn the rest of the lights off in the room when using the lamp
If you find yourself getting upset or worked up because you're tired and your vision isn't working after a long day, take a brain break. Close your eyes and listen to some music you like. Make space for yourself.
These are just a few ideas to get you started, hope they help!
