The Greeks and Romans filled glass spheres with water use them as lenses. However, glass lenses were actually invented in the Middle Ages. It was the Greeks who made the observations, rather than the Romans.
The Greek mathematician Euclid (late 4th century B.C.-mid-3rd century B.C) noted that with greater angles objects are magnified, lesser angles there was less magnification and with equal angles there was none. He also surmised that the size of an object is related to the distance from the eye and studied the perceived shapes of cylinders and cones seen from different angles.
Hero of Alexandria (c. 10 - c. 70 AD), another Greek, showed that the path taken by a ray of light reflected from a plane mirror is shorter than reflected paths between the source and point of observation by using a geometrical method
Titus Lucretius (c. 99 BC - c. 55 BC), a Roman philosopher, thought that light and heat of the sun are composed of minute which pushed and quickly shoot through the air in the direction of the push.
Ptolemy (c. AD 90 - c. 168) studied reflection and refraction. He measured the angles of refraction between air, water, and glass, and adjusted his measurements to fit his incorrect assumption that the angle of refraction is proportional to the angle of incidence.
What they discovered is that the lens would help them see smaller things and that it could make things burn.

This answer is they compare because they both have oars but they have different shapes
When an artist creates an artwork made up of many different shapes all in varying shades of blue, it likely means that they are using color and shape as their primary means of visual expression. The choice of blue as the dominant color could evoke feelings of calmness, serenity, or melancholy. The different shapes may contribute to the overall composition and convey various meanings or emotions within the artwork.
Microliths are small stone tools or weapons man made of different shapes at the middle ston age [mesolithic age]
It seems that many ancient Celts used horned helmets, also, Romans have depicted germanic peoples wearing them as well, there is a theory that these were only ceremonial. During the middle ages many Knights had horns of different shapes on their helmets. A horned viking helmet has never been found, but as Ian Malcolm says: Absence of proof is not proof of absence.
Romans experimented with different shapes of clear glass lenses. This experimentation accidentally resulted in the creation of the magnifying glass.
it can help them see smaller things in ore detail
I don't think this is right but It might be the spectrum of visible light. You know the rainbow?
wide in the middle and stuff like that.

the Romans invented the shapes
The ancient Romans invented shapes.
Romans
Roman citizens in Phoenicia (Lebanon) discovered glass blowing. They found out that If you gather molten glass on the end of a pipe, it could be inflated, and thereafter easily formed into just about any object.

because the Romans thought it would be a good name because it's interesting!
Cells are different shapes and sizes because they have different functions. The functions dictate the shapes and sizes.
