Every day, I follow a rather strict routine of nutritional supplements. While I have my own motivations for it, I can safely say prolonging my life, and biohacking, have been big inspirations.
I make sure to go outside daily - living out here in the woods, I get plenty of opportunity for Vitamin D. This makes other vitamins and supplements that I intake assimilate more easily. - don't hesitate to draw your own judgements.*Note: I am still experimenting with NAC. I have yet to figure out whether or not increasing cell turnover is beneficial or detrimental to reversing aging and maintaining good health.
Prolonging one's lifespan to the point of potentially living long enough to see scientific immortality is hard work. One must balance their enjoyment of life with their ability to endure strict fitness, health, diet, and supplementation regimens - don't lead a miserable lifestyle for a prolonged life, if the entire thing will be spent in misery. Exercise moderation, that is.
Of course, stuffing oneself with pills and supplements is a fraction of good health - healthy sleep habits, and even maintaining good hygiene (lotioning and moisturizing skin) goes a very long way. You must become a nutritionist, a personal trainer (for yourself) a biohacker, a pharmacist, and even a medical doctor if you wish to actually make a meaningful change.
Fitness is important - focus on both strength training (to maintain muscle mass, bone volume, and so on), and cardio (for the general health of your cardiovascular, nervous, and various other organ systems.
Stop adding salt to your food; lower sugar intake, and partake in steamed, stewed, and boiled foods. Occasional grilled food is acceptable, in my opinion. As mentioned before, there is little point to a longer life if it's lived in misery. While counter-intuitive, I always keep in mind the fact that a man who lives to 40 in joy lived a fuller life than one who lived to 120 in misery. Reverse-pseudo-memento-mori, of sorts.
Get plenty of rest. Breathe healthy air, and drink healthy water. This necessitates moving out of the city - urban wastelands are antithema to good health.
Most crucial is avoiding inflammation - taking care of the cells which don't renew is essential, especially the brain, eyes, and so on. Preventing the degeneration of your DNA in the cells that do renew prevents cancr - antioxidants, telomere-lenghtening supplements, and so on are essential.
Lowering chronic stress, and chronic inflammation is crucial, as it remaining parasite and disease free.

Much like the modern diet is detrimental to dental health and jaw development (overly soft foods don't apply enough positive stress to maintain one's teeth), so is the modern lifestyle detrimental to one's eyesight.
A little-known fact is that babies are actually born highly nearsighted. As the child ages, and views objects over a variety of distances (reading, playing outside, watching the stars, climbing trees with friends) the eyes gradually develop and become accustomed to functioning well at a variety of focal distances. The sterotype of the nerd has truth to it - staring at a book, or now, a screen, for hours every single day - with little outdoorsmanship and few male role models for boys, or female ones for girls, kids are locked into their screens.
Worse yet - and these are not my words - there is a concept of "temporary myopia", which is a temporary adaptation of the eyes to viewing shorter distances - and when a child first fails an eye examination, the doctor immediately prescribes high-power lenses, which force the eye to actually change its shape, making reversal difficult (or perhaps impossible, depending on whose research you choose to believe.)
Personally, I've noticed an excellent improvement in my eyesight since I've stopped wearing my glasses, begun active focusing (forcing your eyes to focus on objects just out of view / slightly blurry), anmd performing eye exercises / spending more time viewing at distant objects
The human body is remarkable, and will adapt to nearly anything - much like the brain is a highly plasti cthing (and even regenerates its cells, contrary to previously believed science, so too can the eyes, in my opinion, adapt to their surroundings - what's essential is exercising the discipline and will necessary to create the sorts of surroundings that encourage your eyes, and honestly, the rest of your body, to flourish. That is all.
