This is one of my favourite exercises as you can do it almost anywhere.
Instructions for Near and far focussing:
- Sit in a comfortable position, or stand, this will only take 2-3 minutes at a time.
- Put your thumb about 10 inches in front of you and focus on it.
- Now focus on something else about 10-20 feet in front of you.
- On each deep breath switch between focussing on your thumb and the 10-20 feet object in front of you.
This will strengthen the muscles in your eyes over time and improve your vision overall.
