Can people really turn their eyes inside out?

Yes, some people can appear to turn their eyes inside out, a phenomenon known as "scleral show," where the sclera (the white part of the eye) becomes more visible due to extreme eye movement or certain medical conditions. However, this is not the same as literally turning the eye inside out. This action can also be demonstrated in a more exaggerated manner through certain tricks or techniques, but it is not a common or natural occurrence.
