You are missing one very important exercise which is a lil bit harder to perform. You will need to sit near preferably clear window with a view which stretching far away, better if there is different detailed "sight spots" on different distances, building, trees etc would do perfectly, important thing, view should be stretching far. Focus your vision on something very far, as far as you still can figure out details on object or figure objects from sightview. Than refocus your vision on something close to you but still small, for example, your fingernail tip, till your vision focus on it making everything around blurry, than again on something as far as possible. Do 15 reps. If your eyes hurts, try squint less and focus your vision on something you can observe with a lil bit less effort. Before doing another cycle try to do exercises you described in vid till itch or slight pain goes away. It helps to relax muscles actually doing job and provide them with fresh blood full of oxygen and nutrients. Try to do 3-5 cycles. If your eyes become bloodshed red and you feel that your vision actually worsens, drop this and perform just exercises described in vid. Your eyes are likely already too tired or having some health issue. Your exercises can be compared with warming up/side muscles dumbells exercises, while one I described can be compared with actual heavy bench lifting. There is eye condition where exercises, especially one I described should be taken with moderation - eye blood pressure issues and general vascular issue leading to loss of vision (things like diabet falls in this group). In this case try to focus on healing root condition first, and do eye moving exercises until you feel slight discomfort and drop them if your eyes turn red. Bcs doing full reps in those conditions is like forcing ill person doing gym routines. It easily makes source issue condition become worse and produce further loss of vision. Also, doing some activity forcing you to focus on moving object especially on background which is much "deeper" in perspective can help either. Games like open-air volleyball do great. Also, as any exercises, it works better if you are younger. Elder persons can still find it benefiting, but should be more aware of potential overexertion downsides and lesser progress. Personally, I'm office worker working almost all time in front of a screen and a loner mostly entertaining myself in front of screen in spare time either living at place which weather consists of 8 months of virtually never ending dribbling cold rain, so I stay inside mostly. Those exercises is a thing which keeps my vision never falling lower than -0.25 since I was a teen and likely just due to I do them irregularly when I feel my vision becomes worse than I like it to have.
