Any recommendations for a video or article that explains how vision is a spectrum and how vision loss can affect different aspects of sight (acuity, peripheral, contrast, etc.)?

I'm just starting O&M training and I'd like to share something on social media to help explain to my local acquaintances why they may sometimes see me walking with a cane in the future or sometimes not. I still daytime drive, but need a cane for darkness, depth perception, and bad eye days. I'm excited about the O&M training and I think it will help me feel confident getting around, but I am feeling a little paranoid that people may judge me.
