Reading glasses are usually because someone is far-sighted, and their close-up vision needs help. This commonly begins to happen past the age of 40.
the sound
the sound each glass makes
Near-sided vision is when you can see things close to you but not far away. You need glasses to see things far away. I know this because I am near-sided. Hope this helps you out.
That condition is called presbyopia, where the eye loses its ability to focus on close-up objects due to the natural aging process. It typically occurs around age 40 and is a common condition that can be corrected with reading glasses or multifocal lenses.
Circular glasses provide a wider surface area for striking which can potentially make it easier to create a loud, resonant sound. Straight-sided glasses, on the other hand, may offer a more consistent and controlled pitch due to the uniformity in shape and thickness of the glass. Additionally, the shape of the glasses can affect the timbre or quality of the sound produced.
Near sided is when you can see things that are near clearly and far images are very blurry people that have it need glasses we call these people 4-eyes or bug eyes
In the Striking experiment, sound may be better in circular glasses compared to straight-sided ones. Circular glasses can produce a more uniform distribution of sound waves, allowing for smoother resonance and reduced distortion. The curvature helps in focusing and directing sound more effectively, while straight sides might create sharper reflections and interruptions in the sound wave propagation. Thus, circular glasses are likely to enhance the overall auditory experience.
Dodecahedron. <-- wrong a dodecahedron is a 3 dimensional shape having 12 faces. a 20-sided polygon is an icosagon
A square and a rectangle are 4 sided figures each having 4 interior 90 degree angles
Heptagon - a polygon having seven sides
An isosceles triangle.
It works out as having 5150 diagonals
