Whenever a ray of light emerges obliquely from glass into air, the angle of refraction involving ray and normal is bigger compared to angle glasses near me of incidence Within the glass, and at a sufficiently large obliquity the angle of refraction can actually achieve 90°. In site link cases like this the emerging ray travels along the glass surface, and also the sine of the angle of incidence In the glass, often called the critical angle, is then equivalent to your reciprocal on the refractive index of the material.
The full system thus creates a picture in the world that may be an exact reproduction of the image photographed in space a few minutes earlier.
