Can you stave off a potential new interest?

Isn't that a bit like asking how long a piece of string is? 

For me, I guess it would depend on what the 'thing' was, how much it appealed to me, if there was a cost and it was financially viable, and so on. I'd probably go ahead and give that potential new interest a try, and then if I couldn't do it, or didn't enjoy it as much as I thought I might, I'd then knock it on the head.

Ah, well for me, it is appealing, and it’s totally free lol. I just know I’ll get sucked in the special interest hole, and I really don’t have the capacity for it right now. I am actually distracting myself when it pops into my head, so I don’t get tempted lol

That all sounds good, but as you don't feel you have the capacity for it, then it does make sense to put it 'on hold'. 

I can relate to that! Although I can use reading glasses to crochet etc, I find them uncomfortable so I do it less. Although I also suffer from crippling indecision as to what to actually crochet, which probably stops me more than the eye problems... Some people can manage to knit in the dark! Especially simple things. Personally i feel the need to keep looking at my knitting, but I have done it for less time than crochet, but knitting is easier to do in the dark than crochet.

I do jigsaws online, much easier on my eyes and back than physical ones. I like to do them while listening to audio books or podcasts. But then my mouse hand starts to get RSI or something! 

A hobby I like which is not so dependent on eyes (or hands) is language learning. It can be like a puzzle sometimes. I hope you can find something relaxing which doesn't rely so much on good eyesight.
