In this paper we have assumed a weak-field regime to explore the gravitational lensed photons in a 4 dimensional Einstein–Gauss–Bonnet gravity, which is very much in the limelight these days. The investigation is conducted in three distinct paradigms: uniform plasma, singular isothermal sphere and a non-singular isothermal sphere. The lensing angle associated with the distribution factor of the medium is individually derived for each case and further utilized to study the magnification of the image source brightness, selectively for the uniform plasma and singular isothermal sphere. The attained results are brought forth in contrast with the standard Schwarzschild geometry.

在本文中，我们假设了一个弱场机制，以探索4维爱因斯坦-高斯-贝内特引力的引力透镜光子，这在当今是非常受关注的。该研究以三种不同的范例进行：均匀等离子体，奇异等温球和非奇异等温球。对于每种情况，分别导出与介质的分布因子相关的透镜角度，并进一步用于研究图像源亮度的放大率，有选择地针对均匀的等离子体和奇异的等温球体。与标准的Schwarzschild几何图形相反，得出了所得到的结果。
