The laser procedure works by eliminating the melanin from the surface of the iris, which then allows light to enter and scatter in the stroma. The effect is similar to Rayleigh scattering, in which wavelengths of sunlight hit much smaller molecules in the air and then scatter, which makes the atmosphere appear blue.

这项激光手术通过消除虹膜表面的黑色素，让光线得以进入虹膜，分散在基质层上，从而让眼睛呈现出蓝色。这一过程和瑞利散射的原理类似，当阳光的波长触及空气中的分子散射开来，天空就会呈现蓝色。

The laser treatment disrupts the fragile layer of pigment on the iris, which causes the body to start removing the tissue naturally. While the procedure itself only takes around 20 seconds, the blue eyes do not emerge for several weeks, as the body can only gradually release the pigment.

激光手术会破坏虹膜表面这层脆弱的色素，促使人体自然地移除相关组织。尽管手术本身只需20秒钟，但是要过上数周，眼睛才能变成蓝色，因为人体只能逐渐地释放色素。

The medical industry, ophthalmologists in particular, has not been particularly receptive to the procedure. The skepticism is based on the fact that eyes are one of the most sensitive organs in the human body, and that the procedure is irreversible.

医学界尤其是眼科界对这种手术的接受度不是特别高。他们质疑的依据是，眼睛是人体最敏感的器官之一，而这种手术是不可逆的。
