If you're looking to work specifically in the blindness field, you could get a master's in vocational rehabilitation counseling.

Maybe this isn't the answer you are looking for, but...

Any profession you enter can be of benefit to blind people if you keep accessibility as a major principle you conduct your work by. Architects and city planners can design structures and systems that are accessible from the get go and still retain all the asthetic appeal sighted people crave. Keep in mind, accessibility should be considered for all disabilities. Regardless of what you may choose to do, find some form of disability education classes and get to know people with disabilities and listen to them. That is my two cents anyway.

Assistive Technology Professional

In addition to jobs specific that help people with vision loss (assistive tech, O&M, independent living skills), people can also help in other ways. For our summer camps for kids with vision loss, we've had people come in to teach them self defence and CPR. We've have the kids visit a monster truck show and get to feel the trucks (before the show started), go into cockpits for airplanes, and get to explore an ambulance.

i have often thought about starting an assitive helper business, going out places with clients that they wouldnt normally go by themselves kind of like an adventure firm

While I am low vision, I specialize in IT Accessibility consulting. In my experience, Accessibility can be thought of as a layer across the whole span of Information Technology. Everything from Governance, policy and business architecture to Procurement, project management to development (web, application) to user interface design, Accessibility testing and end user support. Take your pick and build your skills.

You could work as a teacher of the visually impaired (TVI) working in schools to help educate children with visual impairments, a low vision therapist helps train and distribute assistive devices, and a VRT helps people adjust and learn to do everyday tasks or "activities of daily living" at their home or work. Obviously these are very brief descriptions and there are many more jobs (OTs, O&M specialists, etc.) but hopefully this can help you get started.
