Thank you for the additional information. It is very helpful.
As you already know, the decision to undergo cataract surgery is a personal one. The reasons to undergo it is different for everyone. Some patients what to see the needle better while sewing, while others want to read better. In your case, it would be to help with the night-time driving vision.
You have a few options.
1) observe the cataracts and continue as you are with the yellow glasses.
2) try to update your glasses prescription to see if they help
3) opt for cataract surgery.
If you are worried about losing the ability to read without glasses, you can ask your surgeon to implant a lens
that allows for that. This means, however, you'll still need glasses to drive. But the quality if vision should be much improved.
There are new implantable lenses
that attempt to give good near and distance vision. These, however, has there drawbacks and currently not the majority of lenses implanted during cataract surgery.
So, I would revisit with your ophthalmologist
for an exam. If you decide to go with surgery, ask about making your reading vision clear without glasses and then wearing glasses to drive.
