I am legally blind now in my left eye but not my right, does this need to be put down as legally blind?

It depends on whether your vision in your right eye is below 20/200 or not.

The IRS defines Blind as follows:

Being legally blind in one eye may not qualify you for the tax deductions. To qualify you must have vision below 20 degrees in both eyes or your vision in your best eye is 20/200 or below. ... If you are legally blind in one eye but your eyesight is better than 20/200 in your other eye you would not qualify.
