taut
During distant vision, the ciliary muscle is relaxed, the suspensory ligament is taut, the convexity of the lens is increased, and light refraction is decreased. During close vision, the ciliary muscle is contracted, the suspensory ligament is relaxed, lens convexity is increased, and light refraction is increased.
The suspensory ligament is lax. I know this because I just finished this homework.
Yes, the ciliary muscle is relaxed for distant vision, but is contracted for close vision.

The sensory ligament, also known as the zonules of Zinn, connects the ciliary body to the lens of the eye. It plays a crucial role in the process of accommodation, allowing the lens to change shape for focusing on objects at varying distances. When the ciliary muscles contract, the tension on the zonules decreases, allowing the lens to become more rounded for near vision. Conversely, when the muscles relax, the zonules pull on the lens, flattening it for distance vision.
Suspensory ligaments, also known as zonules, are thin filaments that connect the ciliary body of the eye to the lens. These structures help to hold the lens in place and change its shape for focusing on objects at different distances. When ciliary muscles contract or relax, they alter the tension in the suspensory ligaments, which in turn changes the shape of the lens to facilitate accommodation for near or distant vision.
A golden eagle has great vision and can see at a great distance during the day.
No, light refraction does not increase during distance vision. Light refraction occurs when light travels from one medium to another of different optical density, causing it to change direction. The amount of refraction is determined by the difference in optical density between the two mediums, not by the distance of the object being viewed.
No, their distance vision is rather poor.
Depending upon the amount of farsightedness, symptoms can range from none to clear distance vision but blurry near vision, to blurry distance and near vision

The best eyeglasses for distance vision are typically single vision lenses with a prescription specifically tailored to correct your distance vision. It's important to consult with an eye care professional to determine the most suitable lens type and prescription for your individual needs.
