The blind spot in the human eye is an area on the retina where there are no photoreceptor cells, specifically rods and cones. This region lacks the ability to detect light and therefore results in a loss of vision.
The retina is a layer of tissue at the back of the eye that contains photoreceptor cells responsible for converting light into electrical signals. Rods are sensitive to low light conditions and are responsible for peripheral and dim light vision, while cones are responsible for color and detailed central vision. However, there is a small portion in the retina called the optic disc where the optic nerve exits the eye. This area lacks rods and cones, making it unable to detect light and creating a blind spot.
In summary, the blind spot is the result of the absence of rods and cones in a specific area of the retina, known as the optic disc. This region lacks the ability to sense light, leading to a loss of vision in that particular spot.

The duration of action is an important parameter in pharmacokinetics as it helps to determine the dosing frequency and the efficacy of the drug.
The MEC is the minimum concentration of a drug in the blood required to produce the desired therapeutic effect. It represents the lower threshold for effective drug action. On the other hand, the declining blood concentrations refer to the decreasing levels of the drug in the bloodstream as it is metabolized and eliminated from the body.
To determine the duration of action, it is important to assess the time period during which the drug concentration in the blood remains above the MEC. This ensures that the drug concentration is maintained at a level that produces the intended therapeutic effect. Once the drug concentration falls below the MEC, the desired effect may diminish, and the duration of action can be considered to have ended.
