The biconcave structure is the "lens, but his focuses the light, it does not adjust for the amount of light. The structure that adjusts for the amount of light entering the eye is the "iris"
being capable of carrying an amount of weight without falling or breaking
They have no nucleus, so they sink in in the area where the nucleus should be. Oxygen binds to the surface of the cell, so the increased amount of surface area due to the biconcave shape gives it more space to carry oxygen.
The chambered nautilus uses gas-filled chambers within its shell to control its buoyancy. By adjusting the amount of gas within these chambers, the nautilus can regulate its position in the water column.
Iris controls the amount of light entering into the eye.
Guard cells, which are specialized cells that surround the stomata, are responsible for adjusting the size of the stomatal pore. When the guard cells take up or release water, they change shape and control the opening and closing of the stomata.

The diaphragm or iris controls the amount of light passing through the specimen in a microscope. By adjusting the diaphragm opening, the amount of light reaching the specimen can be regulated, thus providing better clarity and contrast during observation.
The iris is the part of the eye that adjusts in response to light conditions. It controls the size of the pupil, which determines how much light enters the eye. In bright light, the iris contracts to make the pupil smaller, and in dim light, it dilates to make the pupil larger.
stage opening
The diaphragm, located beneath the stage of a microscope, controls the amount of light that reaches the specimen by adjusting the size of the opening. By adjusting the diaphragm, you can control the intensity and focus of the light for better visibility.
