Getting over the fear of asking for help is paramount, since if you aren't comfortable with yourself and the blindness, that's going to really get in the way of dating since it will impede your confidence. It's totally fine to ask for help! Your date wants to meet up and learn about you, and some of the quirks that come with vision loss is that you'll need a little help here and there which is very easy to provide.
Research the menu before you go, most menus are available online. If not, no worries, just ask your date what's on the menu. That inspires discussion about what foods you both like and dislike and is a great icebreaker. Give your date a little run down on sighted guide, explain that you'll need to touch/take her elbow when you need to move to a counter if that's the kind of place you are going, otherwise don't worry about having them read the check when it's delivered, plus you can do things that will make them think about quick forms of accessibility like creasing a check for you along a signature line so there is a tactile demarcation where you need to sign when paying with a card.
Don't be afraid of these things. I lost my vision 5 years ago and it definitely didn't stop me from dating. My dates know up front that I'm blind, and the people I meet are curious or don't mind it at all. Once they see how things are managed and if they see you are confident and can put them at ease, things will progress smoothly. If you keep fretting about your misgivings and fears, that's going to grind the date to a halt.
Also know that rejection is always a potential occurrence, so sometimes no matter what, chemistry just won't be there and you may go through a string of bad dates. This happens to everyone, blind or not, so just be prepared to accept it and move on to another match. You can do it, go out there and get some experience! Have fun! I've also written a primer for dating while blind which I like sharing with potential dates:
