It sounds like you're asking to turn this, where we can see you have 101 rep and Shog9 has 235k rep:
Into this, where we can't:
In my personal experience, it isn't an eyesore and I don't have any trouble focusing my eyes away from the rep first. The name is a different colour and stands out, so my eyes just travel straight to it. (If you're colour blind I could understand this being a real problem; there limited recourse available on the SE engine for those needing accessibility measures.)
From a moderation perspective it's kinda useful: if something looks funny, it probably needs attention, and this helps us gauge how weird a situation is.
For example, on one of my sites, a 20k user asking or answering several questions in a row is usually not a problem, but a low-rep user doing the same is more often than not needing to slow down and probably making problematic contributions. The fact their reputation is on display lets me tell them apart during a glance at the question list.
