Should I get transition lenses?

I got a prescription and I'm supposed to only use my eyeglasses in front of a screen or while driving at night. I didn't get transition lenses because I figured I'm only going to use my eyeglasses indoors or at night.

But when I started a new job, I had to look at computers while going in and out the door to attend to people outside the door. I can see the sunlight outside and I have to squint my eyes but I don't stay long outside and I'm still under the shade when I step out the door. I step outside for only a couple of seconds to a few minutes. I don't want to wear sunglasses because then I would have to take it off when I'm inside. And then I would have to switch to my eyeglasses because I'm using the computer.

Should I get transition lenses?

The optical store told me it won't get dark unless I step outside though.

Thank you.
