The expanded material may soften a little after a long time, but silica gel will not. Silica gel has high hardness, good inertia and will not collapse. However, it is recommended not to wear glasses within one month after operation, and try not to wear glasses all the time after full recovery, which will have a little impact. I also wear glasses after rhinoplasty with Han Shengke, and there is no collapse of the prosthesis, but now I don't wear glasses and occasionally use contact lenses.
