If you haven’t seen one yet, maybe check in with a neurologist. Sometimes vision loss is a sign of something going on with the brain or optic nerve. And if you get the chance, ask your eye doctor if there’s a specialist they recommend you visit based on your symptoms.
Yes you can still be a chef! You might have to take things a bit slower but most of the adaptive techniques for the kitchen are a matter of practice. Work on chopping stuff without looking and, if you don’t do it already, organise your kitchen and work space so you know in general where stuff is. You might want to get some skills training to learn kitchen safety and how to tell what’s going on with things you’re cooking without looking. I use fairly simple tools like a ceramic tile that rattles when water is boiling, talking timers and thermometers, and braille labels or puff paint dots on stove/oven knobs.
You don’t need to change anything in your house unless you just want to. Put some puff paint or raised dots on your washer and dryer and dishwasher so you know where the settings are and that’s really it. Oh, and find out what all the circuits in your circuit box go to and label them or make a note in your phone. You can get in home training later if you think you need it.

Are you familiar with [Christine Ha] (http://www.theblindcook.com/about/)? She's a very successful blind chef.

It's not really advice, but I thought it might help you to learn more about how she approaches it.

I would suggest seeing if where you are at has some sort of vocational rehab program- if you do, usually there is a school that can help you prepare. We have one in Salt Lake City called the Division of Services for the Blind and Visually Impaired. I also know there is a really nice school in Denver Colorado and some others in the U.S. These kinds of schools and programs can help you learn how to adjust as well as giving you skills in order to continue living independently. Also there are apps that you can download and start to use on your phone- my husband's favorites are money reader, SeeingAI. Also- my husband loves this little device called a Victor's Stream. It's a neat little device that allows him to make recordings and bookmark those recordings. As well as downloading podcasts and some other things.

Rely less on your vision and identify areas where you heavily rely on vision. Learn the layouts of places you visit frequently. Learn to take public transit to those places. Research and practice using the accessibility features on phones and computers. Learn to use a long cane now, and find an O&M in your area.
