Thank you very much @ozhiya for your interesting participation and for sharing your experiences with us. According to you, certainly people often downplay the issue of peripheral vision, because unfortunately "nobody knows what they have until they lose it". I can not comment on your vision problems because I do not know the internal physical damage, but I can Assure you that there are many mental exercises that can help you substantially improve peripheral vision. Greetings and a respectful hug.
