Oooh! What a minefield! I think this is very complicated, perhaps without a definitive answer. Personally, I'd use either. The first agrees with sentences in the subjunctive such as, "It's essential he BE here tomorrow." So that's a point for using SEE. However, many people, especially in the UK, would use IS rather than the subjunctive. As you know. (It's essential he IS here tomorrow.) So that's a point for using SEES! If I'm feeling formal I'll go for the subjunctive: SEE. If I'm chatting to a friend: SEES It won't be a conscious decision. It'll just come out of my mouth. My BRAIN will be aware of the subjunctive nature and that's why SEE might come out. We have more questions here! Is the subjunctive dying? I'd say, yes! But I like it! Does the use of NO ONE confuse the issue? People sometimes argue if NO ONE is singular or plural. I just mention this as a possible source of muddle. Does PREFER work in the subjunctive in other sentences? Let's try it: I prefer that Harry BE/IS here. It is important (that) Harry BE/IS here. Clearly BOTH correct in this one! But I suspect Americans would prefer the BE/subjunctive. What do you feel? My feeling is that PREFER is a wee bit borderline. Whilst I like, "I prefer that no one SEE me like this," I do NOT particularly like, "I prefer that Harry BE here." Or do I? If I say it a few times, like the Queen of England, very poshly, I start to like it! I really need to explore this more. I suspect Shakespeare would have something to say about this.

In American English, ‘prefer’ can describe the subjunctive mood. It’s correct and natural. It most cases it’s not a matter of being correct, but one of meaning. It expresses a wish or a hypothetical. I prefer that she marry someone with integrity. (It’s my wish. No one is actually getting married.) I prefer than no one see me after my surgery. (It’s my wish. I might not have had my surgery yet.) Many native speakers do use ‘marries’ and ‘sees’ above, so it really doesn’t sound too wrong. There are also regional variations (some versions of English are less likely to use the subjunctive.) Back to your example: I prefer that no one see me like this. (This is correct if I’m expressing my wish for the future.) I hope that no one sees me like this. (This is correct if I’m indicating my current state and my current hope) I prefer that no one sees me like this. (This is correct if I’m indicating my current state and my current preference.) I prefer that no one sees me like this. (This is very common but could be considered incorrect in the US if I’m expressing my wish for the future.)

More thoughts: I've found a number of uses of PREFER in the subjunctive: The Pentagon (USA) would PREFER the plan BE considered with...." "I prefer him to BE there early..." Logically then, "I prefer no-one SEE me..." would be used, by some, as choice, with the verb PREFER. Or change it to SEES if you don't like the subjunctive. Or change it to, "I'd prefer it IF no one sees me like this. Or, "I'd prefer it if no one SAW me like this." I think there are so many combinations of I prefer/I would prefer/see/sees/saw that it is no surprise there are whole forums dedicated to this!

Third answer from me! I'm picking up far more "I'd prefer no one SEE me like this." (I WOULD PREFER....) Nicely subjunctive. Fewer "I prefer... This is YET ANOTHER thought to pursue.

The second one is correct because "I" is a singular pronoun and when you use any singular pronoun you are sure meant to use a plural in your verb form. I hope I make sense and I stand to be corrected
