Obtain some UV cure hard coat from your lab. You will need to purchase a uv light to cure the coating but it will shine the edges and seal the holes. Application will be with a paint brush any mistakes can be removed before you cure the coating with out any problems.
This discussion is making me miss Chris Ryser something awful.

If the process is done correctly there is no need to do anything to the holes or the edge. Change the cutting bit when it is due. Yes it cost money to replace the cutter but the damage done by not changing it is far greater. If you believe the cutter will last 1000 cuts change it at 500 you will be amazed at the quality improvement. Most edgers do an outstanding job edge polishing if the sizing is correct and the process is working as designed.
There is no definitive answer to the question when to change the cutter. How many poly do you do, how thick is every lens as drilling a -6.00 wears the bit way more than -0.50. No one collects that kind of data. The best way would be to run a test lens every day and look at the hole with a loupe and observe the quality of the cut. Actually Trivex will dull the cutter faster than poly, but a dull bit does not cause stress cracks in Trivex.
It’s simple. If the drill bit is sharp, cracks won’t be an issue. Spend a few bucks and replace the bits on a regular basis. In edger, drill station, Dremel, etc.
None of the poly drills have cracked under my watch in over 6 years.
I bend light. That is what I do.
