I can only assume that by individual, you mean my mind or consciousness. The answer is that the senses don't depend on the mind. That's why they're objective. Even if I had a brain with no consciousness, the signals from my senses would still fire, there just wouldn't be anything on the other end perceiving them. While it's true that my perception is subjective, that doesn't matter because it's not changing anything that my senses are telling me.
Subjective merely means that it's MY assessment of reality from what I've perceived.
Objective means that which is, regardless of my assessment of it.
Since my senses are objective and the senses of other people are also objective, I can compare my subjective assessment with somebody else's to derive facts by which to tell when people are lying about their assessment.
If everybody actually sensed things differently, then it would be impossible to make this comparison. Since that is not the case. It logically follows that everybody's senses are roughly equal with maybe some small inconsistencies here or there cause by bad subjective assessment.
Being blind or deaf simply means that you have less sensory organs. That means the amount of objective sense you can assess is lower, but the things that you can still assess with your remaining senses is still just as accurate as anyone else's.
When you say correct way of perceiving the world, you have to define correct. Do you mean the best way for your survival? The most accurate way in terms of navigating reality? Is it correct because even though it's not accurate it makes you moral somehow? I'm going to go with the second one until you define this better.
The correct way to view the world in this case would be pragmatically. If you're asking: Do we view the world correctly? Then the answer is always yes.
