Will my upper bleph scars ever become invisible? What can I do if they don't?

Plastic surgery scars require attention after surgery so that they remain cosmetically-appealing and barely noticeable. In our office, we use a protocol for scars that minimizes their activity in the 6-8 weeks after surgery. If you have late plastic surgery scars, you may also require laser and RF therapy to help reduce the longterm effects of the scarring. Keloids, hypertrophic scars, widened scars, red scars, and hyperpigmented scars all require scar modulation with topical creams followed by lasers and RF therapy. Topical skincare should be directed to a specific need, whether for pigmentation or hypertrophy and our office can guide you through the process to obtain the correct Plato’s Scar cream or Melarase cream for hypertrophy and discoloration. In terms of lasers, we would employ the vbeam laser for redness, Venus Viva RF, PRP microneedling, chemical peels, and Morpheus 8, fractional erbium, or fractional co2. All of these have their individual benefits. Most of all, we recommend you visit a solid plastic surgeon who understands surgical scar revision, laser therapy, and RF therapy for scars.

First of all, you just had surgery less than two weeks ago.  Take it easy on yourself and realize that it takes the body time to heal.  That being said, I would reserve judgment on your final results for at least 3 to 4 months. 
When performing eyelid surgery, a board-certified facial plastic surgeon will make the incision inside the crease of the eyelid and suture underneath the lid, where the stitches cannot be seen. It is also fortunate that the skin on the eyelid is very thin and heals so well that the scars will be virtually invisible. Massaging the scar, once it's healed, can help break down the collagen and make it blend into surrounding skin faster.
I hope this helps!

You are very early in the healing phase.  We expect the scar to be visible for several weeks.  With time an upper eyelid scar should soften and flatten, and is usually minimally visible.  I would not be putting a lot of makeup onto it at this point if it appears inflammed still.  Some people will lose pigment in the scar, and will end up with a white line.  This is only visible with the eye closed and easily covered with makeup. So give yourself time to heal.  I would recommend some tinted glasses for now if you are concerned about the appearance.
