simplest possible telescope
Telescopes typically use convex lenses (also called objective lenses) to gather and focus light from distant objects. These lenses help magnify the images and make distant objects appear closer and more detailed. Eyepieces with different magnifications are then used to further enhance the view.
The lenses used in reflector telescope is the concave lens.
Lenses had been known for some time before the telescope was invented. No one really specifically "invented" the telescope lens, they simply used existing equipment (lenses) in a new device (the telescope).
Most telescopes use refractor lenses. Sometime a telescope will use reflector lenses.
On eyeglasses? Two lenses = bifocals Three lenses = Trofocals
