I have issues with my eyes and tiredness as well. From what I know eyes can have an issue with their "muscles." Simple excercises like looking out of the corners and tops of your eyes, and holding your view there for a few seconds, before moving to another side of your eye, and repeating all this can help "strengthen" the muscles. It can be disconcerting at first but it can pay off. There might even be a little strain and mild pain. Talk to someone about them, and do a bit of reading. I've also been told a lot of time on the computer, or reading, or anything that causes your eyes to look at the same distance focal point can cause issues. I was told, if possible, every hour go look out the window. Focus your eyes on something far away if you've been staring at a book or screen. The effects of which aren't limited to just your eyes.

It's worth going into an optician to talk about all this. They'll tell you if you need to see an optometrist and the optometrist will tell if you need to see a fully qualified ophthalmologist. The opticians will be free, the optometrist might have a charge, but it won't be too expensive. It's unlikely you'll need an ophtalmologist, who could be expensive, but it's not worth thinking about until you're told you need it. Even an optometrist could be a massive help.

As for migraines, optical or otherwise, I spoke to my endo about it. It's rare-ish but it does happen that hormonal issues cause migraines, or be another factor in a range of issues that cause them. I've had a few. Oestrogen changes can cause them (even missing a dose or two,) and it's worth mentioning to your doctor, especially if you feel there's a connection. It can be an issue in trans care, for both men and women. As well as any contraception or menopause issues with women, and often just aging with men.
