If the area in the center of your vision is blurred, that is likely to be macular degeneration. If everything is blurry especially in strong light, it's likely to be a cataract. In any case, see a doctor.
You usually want to pan when you are photographing a moving subject. This will make the subject appear sharp and the background blurred. If you don't pan, the subject will be blurred and the background sharp (which might be the effect you want).

It is the one place on the retina where the image of the lens is 'in focus' i.e. sharp
No, diffuse reflection scatters light in various directions, resulting in a blurred or soft image rather than a sharp one.
The macula lutea is a small, oval-shaped yellow spot near the center of the retina in the eye. It contains a high concentration of cone cells that are responsible for producing detailed central vision. The macula lutea is essential for sharp and clear vision, especially for tasks like reading and recognizing faces.
To achieve a professional-looking blurred background in photography, use a wide aperture (low f-stop number), focus on your subject, and ensure there is distance between your subject and the background. This will create a shallow depth of field, resulting in a blurred background while keeping your subject sharp.
Central vision refers to the area of the retina with the highest concentration of cone cells, which are responsible for sharp, detailed vision. It is essential for tasks like reading, driving, and recognizing faces. Damage to the central vision can result in conditions like macular degeneration.
They correct the path of the light entering the eye so that it will focus a sharp image on the retina.

The fovea or fovea centralis that is a pit in the central region of the macula of the retina with a high concentration of cone photoreceptors (red, blue and green) that allows for 100% visual acuity including color vision comprises less than 1% of retinal size but takes up over 50% of the primary visual cortex in the brain.
They make a sharp cheddar kind as well as several others.
Damage to the fovea, the central part of the retina responsible for sharp central vision, would significantly impair your ability to see fine details. This could result in blurred vision, difficulty reading, or problems recognizing faces, as the fovea is crucial for tasks requiring high visual acuity. Peripheral vision may remain intact, but central vision would be compromised, affecting activities like driving or any task that requires focused sight. Overall, foveal damage can lead to challenges in daily life due to the loss of precise visual input.
