I have low vision due to fighting glaucoma for over 30 years. I now have no central vision in left eye, and only the lower half of field in the right eye. Meetings are often a challenge for me. The biggest problem is glare that reduces my vision to the point where I can't recognize people across a table or see their facial expressions which reduces effective communication. Dim light from overhead florescent lights and from open windows creat worse glare. Bright light is the best cure.
When lights are turned down to show slides etc., often the screen is too small for me to see clearly. One idea is to offer access to slides on personal computers or phones for those that can't see screen well. My Rotary Club of Pinellas Park offers zoom access to club meetings and I can see that better than when attending live meeting.
