One way is to focus on Naruto's other senses. For example, his sense of smell could become super enhanced, like a ninja version of Daredevil. He could use it to track enemies, find his friends in a crowd, or even detect hidden traps. His hearing could also be sharpened, allowing him to hear the faintest of footsteps or the rustling of leaves from afar, which would be useful in combat situations.
One possible reason could be overusing his special powers like the Rasengan or Sage Mode. These techniques might have some sort of negative impact on his eyes over time. For example, if he doesn't control the chakra flow properly during these powerful moves, it could damage his optic nerves gradually.
He has trouble moving around. Without sight, he can't easily navigate the village or the forest. He might constantly bump into things. Also, in combat, he can't see his opponents' attacks coming. It's a huge disadvantage compared to when he could see.
A 'Naruto Secretly Blind' fanfiction could be centered around Naruto's secret being a major plot device. It could be that an enemy discovers his blindness and tries to use it against him. Naruto then has to find new ways to fight and protect the village. His blindness could also be the result of a powerful jutsu gone wrong, or perhaps it was a sacrifice he made for the greater good without anyone knowing.
It really depends on the specific fanfiction. However, it could be the blind samurai themselves as a main character. They would be the focus of the story, with their journey and development being central. There might also be Naruto characters who interact with the blind samurai, like Naruto himself. Naruto's positive and determined attitude could contrast with the more reserved and perhaps wiser blind samurai.
One common theme is overcoming adversity. The blind OC has to deal with the challenges of being blind in a world full of ninja battles. Another theme could be the discovery of inner strength. Since they lack sight, they have to find other ways to be powerful.
One possible plotline could be that fem Naruto has to overcome her blindness to prove herself as a ninja. She might develop unique fighting styles or sensory abilities that compensate for her lack of sight.
One storyline could be Naruto gradually losing his sight over time but hiding it because he doesn't want to worry his friends or seem weak. He could struggle with simple tasks like reading scrolls or finding his way around Konoha without making it obvious.
Overcoming adversity is perhaps the most prominent theme. Naruto faces many challenges that come with being blind in a world where sight is so important for a ninja. He might be underestimated by his enemies or even some in his own village at first. But he uses these situations to prove himself. It's inspiring to see how he turns his weakness into a strength, and this is a common thread in many 'naruto blind ninja fanfiction' stories.
