Cats have better night vision and can see in low light conditions due to a higher number of rod cells in their eyes. Dogs have better motion detection and peripheral vision, but their color vision is not as strong as cats.
Sharpness of vision is also called visual acuity.-Visual acuity is determined by the ability to see visual details (in normal light).
visual "visual" is strictly an adjective though sometimes used colloquially as an noun. The noun "sight" is "vision". I assume you are not talking about gun sights.
A visual field test is typically performed to determine losses in peripheral vision. It involves staring at a fixed point while lights of varying intensity are shown in different areas of your peripheral vision, and you indicate when you see them. This helps to map out any blind spots or areas of reduced vision in your peripheral field.
Rod cells are specialized visual receptors that play a key role in night vision and peripheral vision. They are located in the retina of the eye and are more sensitive to dim light than cone cells, which are responsible for color vision in bright light.
Blurred vision can be caused by issues with the occipital lobe, which is located at the back of the brain and is responsible for processing visual information. Injuries or dysfunction in this area can lead to visual disturbances, including blurred vision.
audio If vision is to visual then hearing is to sound or audio.
Cones that do not respond to light cause vision problems, particularly in the daytime. They are responsible for color vision and detail, so dysfunction can lead to color blindness and reduced visual acuity.
Vision enhancement refers to various techniques and technologies designed to improve visual perception and clarity for individuals with vision impairments or low vision. This can include optical devices like magnifying glasses, electronic aids such as digital magnifiers, and advanced systems like virtual reality or augmented reality applications that aid in navigation and object recognition. Additionally, vision enhancement encompasses therapeutic approaches and training that help individuals maximize their existing vision capabilities. Overall, the goal is to enhance the quality of life and independence for those with visual challenges.

Normal vision in both eyes results in the right half of the visual field being dominant. The absence of vision in both eyes results in the left half of the visual field being dominant.
Sharpness of vision is also called visual acuity.-Visual acuity is determined by the ability to see visual details (in normal light).
Microbats generally have poor vision compared to other mammals, as they rely primarily on echolocation to navigate and hunt for prey in low-light conditions. Their eyes are adapted for low-light sensitivity rather than sharp visual acuity, which allows them to detect movement and differentiate between light and dark. While some species may have better vision than others, their reliance on sound makes their visual capabilities less critical for their survival. Overall, microbats are not known for their visual prowess.

Double vision (diplopia), moving or blurred vision due to nystagmus (involuntary rapid movements of the eyes), reduced visual acuity, reduced visual field.

The Titmus test, also known as the Titmus vision test, is a method used to assess visual acuity and depth perception. It typically involves the use of a specialized instrument that presents various visual stimuli, including 3D images and patterns. The test is commonly employed in occupational health settings to evaluate an individual's vision capabilities, especially for jobs requiring precise visual skills. Results help determine if a person meets the necessary visual standards for specific tasks or professions.
