A method for modifying the refractive index of an optical polymeric material. The method comprises continuously irradiating predetermined regions of an optical, polymeric material with femtosecond laser pulses to form a gradient index refractive structure within the material. An optical device includes an optical, polymeric lens material having an anterior surface and posterior surface and an optical axis intersecting the surfaces and at least one laser-modified, GRIN layer disposed between the anterior surface and the posterior surface and arranged along a first axis 45DEG to 90DEG to the optical axis and further characterized by a variation in index of refraction across at least one of at least a portion of the adjacent segments and along each segment. 种用于改变光学聚合物材料折射率的方法。所述方法包括用飞秒激光脉冲连续地辐照光学聚合物材料的预定区域以便在材料内形成梯度折射率的折射结构。种光学装置，包括：具有前表面和后表面以及与两个表面相交的光轴的光学聚合物晶状体材料；至少层由激光改性的GRIN层，其布置于所述前表面和后表面之间，并沿着相对于光轴成45度到135度的第轴线布置，且其特征还在于横过相邻段至少部分的至少之以及沿着每段的折射率变化。
