Convex lenses
If the object is of the same width and tapers from thick to thin, it may be a wedge.
The area of rock that flows like a thick liquid is called lava. Lava is molten rock that erupts from a volcano and can flow slowly downhill, resembling the movement of a thick liquid.
The very thick liquid found deep underground is called crude oil. It is refined to produce various petroleum products such as gasoline, diesel, and jet fuel.

ANSWER:No. The glass isn't thin enough to be effected by the gradient temperature change. If they were thinner, maybe. But most eye glasses are thick enough to accept the change in temperature.
Two basic kinds of lenses are converging lenses, which focus light rays to a point, and diverging lenses, which spread out light rays. Converging lenses are thick in the center and thin at the edges, while diverging lenses are thin in the center and thick at the edges.

Thick lenses have more curvature and can focus light at different points, while thin lenses have less curvature and focus light at a single point. Thick lenses are used in cameras and microscopes for magnification, while thin lenses are used in eyeglasses for vision correction.
Thick concave lenses have shorter focal lengths than thin concave lenses. This is due to the increased curvature of the lens surfaces in thick lenses, which causes light rays to converge more quickly to a focal point.

That's commonly called a border. Borders can be as thin as one pixel, or as thick as you want !
Concave. The opposite- thick in middle, thin at edges- is convex.

Convex lenses, which magnify, correct hyperopia. Below, is a previous wiki answer to this question in detail.Convex are thicker in the middle and thin out at the edges. These lenses magnify and are used for reading glasses and to correct long-sightedness (hyperopia).Concave lenses are thin in the middle and thick towards the edges. These lenses shrink things and are used to correct short-sightedness (myopia).A good example of this is to take a spoon and look at your reflection in it. Looking at the concave side of the spoon (the front) will make you look smaller, looking at the convex side of the spoon (the back) will make you look biggeRead more: Which_type_of_lens_magnifies_-_convex_or_concave

A thick lens has varying thickness across its surface, which affects how light is refracted. A thin lens is assumed to have a uniform thickness, simplifying calculations in optics. Thick lenses can produce more complex optical effects compared to thin lenses.
