normal float glass screen is made of a number of glass sheets which can be standard.
Yes, its just that a magnifying glass has a different prescription than eyeglasses.
The invention of plastic, enabled the production of both bullet-proof, and toughened safety glass. Since both these products have a plastic sheet sandwiched between them.
Yes, but not all glass under ordinary circumstances. Ordinary window glass can be broken by a snowball (I have seen it happen). Plate glass and automotive glass are more resistant to breakage. Also, snowballs sometimes have extraneous objects, such as pebbles, packed into them, and these can break even more resistant glass. All of this depends, of course, on how hard the snowball is thrown. If the person throwing the snowball is moving, for example in a vehicle, or the snowball is thrown downward to accelerate under gravity, or the snowball hits a moving vehicle, even a soft snowball could break resistant glass.

Quartz glass is made from pure silicon dioxide and has a higher melting point, better transparency, and superior thermal and chemical resistance compared to ordinary glass. This makes quartz glass more suitable for high-temperature and high-pressure applications where regular glass might deform or break down.
For one, the US President uses bullet proof glass.

Boric oxide is added to ordinary glass to increase its thermal resistance and chemical durability. It also helps to lower the melting temperature of the glass batch, making the manufacturing process more energy-efficient.
Boric oxide is added to ordinary glass to increase its resistance to heat and chemical corrosion. It also helps reduce the coefficient of thermal expansion, making the glass less likely to break from sudden temperature changes.

A bullet resistant glass screen is made of a number of glass sheets which can be standard thicknesses window glass, separated by air gaps. Security films, preferably made of polyester, are provided on the front and rear surfaces of the glass sheets. A pressure sensitive adhesive can be used to adhere the security films to the glass sheets. The resistance off the screen to penetration by a bullet is increased by increasing the thickness of the air gaps. There is also a metal net on both sides of each glass pane to stop it shattering if a bullet hits it.
