A spherical mirror and a thin spherical lens

Ever Wondered how can people enlarge things or look in the mirror and see themselves? This is a result of something called "spherical optics. Spherical optics is a very cool science that deals with the properties of light as it travels through or bounces off of round shapes. Now let us analyze two circular shapes which are important: a spherical mirror and thin lens

Now remind you a concave mirror. Concave and convex NOAIDA lens Spherical has shiny ball like finishing curve shape of the inner surface is found in this type or from outer side it looks similar to a spoon. As light rays strike these mirrors, they reflect off the curved surface and rebound in a new direction. This is what we do before receiving a view of ourselves.  

A Guide to Spherical Optics

There are only two ways by which light can bounce back from a spherical mirror - it could be either as concave reflection or convex reflections. Examples of concave mirrors include anything that curves inward like the inside of a bowl. If light hits a concave mirror, it reflects towards the centre. This fools the brain into thinking that it is a bigger and nearer image. And this is why when we look into a concave mirror up close enough to it and in its focal length our face will start looking large, hence used as makeup mirrors

Now, back to thin spherical lenses. The problem is when light goes through a lens, it can refract in one of 2 directions: converging or diverging. A converging lens is convex like the front of a magnifying glass. Pros When light passes through a converging lens, it bends inwards and enables imagination of the images. As such, this NOAIDA sphere lenses  is good for reading and noticing smaller things.
