It is important to note that the refractive index of a material can vary with the wavelength of light, so it is not accurate to say that the refractive index is simply 16 or 167 without specifying the wavelength. **

It is important to consult with a medical professional and the Bundeswehr's recruitment office for specific guidance on vision requirements for this role. **

If the problem persists, it may be a motor issue, and you should contact a professional technician for further assistance. **
