A glass filter assembly includes a circular glass substrate, an annular first anti-fragility layer, and a second anti-fragility layer. The circular glass substrate includes a first surface and a second surface opposite to the first surface. The first anti-fragility layer is concentrically adhered to the first surface. The outer diameter of the first anti-fragility layer is greater than or equal to the diameter of the circular glass substrate while the inner diameter of the first anti-fragility layer is smaller than the diameter of the circular glass substrate. The second anti-fragility layer is concentrically adhered to the second surface. The outer diameter of the second anti-fragility layer is greater than the diameter of the circular glass substrate while the inner diameter of the second anti-fragility layer is smaller than the diameter of the circular glass substrate.
