Diopter adjustments can be made to the ocular lens.
A 50mm lens has a diopter of 20.
Diopter is the unit of the power of lens
The diopter power of the crystalline lens can vary, but it typically ranges from around 20 to 30 diopters. This power helps the lens to focus light onto the retina in order to form clear images. As people age, the flexibility of the lens decreases, affecting its diopter power and resulting in presbyopia.

The magnification of a lens can be calculated using the formula: Magnification = 1 / Focal length of the lens in meters. So, for a 5 diopter lens, the magnification would be 1 / 0.2 = 5x.
Diopter is a unit of measurement of the power of a lens. The word "Magnify" is a verb that is defined as making something appear larger than it is with a lens or microscope.
The unit of measurement of a lens's refractive power is diopters. It is denoted by the symbol "D" and is used to measure the ability of a lens to converge or diverge light.
One diopter is defined as the reciprocal of the focal length in meters. Therefore, 1 diopter equals a focal length of 1 meter. In other words, if a lens has a power of 1 diopter, it will focus light at a distance of 1 meter.
The SI unit of power of a lens is the diopter, which is represented by the symbol D. It is defined as the reciprocal of the focal length of the lens measured in meters.

Your viewfinder may be blurry due to a dirty lens or misaligned diopter. To fix it, try cleaning the lens with a microfiber cloth and adjusting the diopter until the image appears sharp. If the issue persists, consider seeking professional help.
A 4x microscopic lens has the dioptre value of 16 dioptres. You can use this conversion method: 1d=0.25x So to justify and prove my answer you can multiply 4 quarters for each unit (4 units) equaling 16 dioptres. I hope my answer has been of assistance
