In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are:<u> more </u><u>sensitive</u><u> in the dark than </u><u>cones</u>.
The retina extends through the posterior portion of the eyeball is the innermost layer and in it are the photoreceptors: cones and rods.
Rods and cones are the two types of photoreceptor cells in vertebrates that capture light energy (photons) and convert it into electrical signals.
- The rods are sensitive to changes in light, since their detection thresholds are low, so they only come into operation when the light intensity is low (scotopic vision or night vision).
- Scotopic vision has relatively low acuity, as the details of an object cannot be discerned or its color appreciated.
- On the contrary, cones have a much higher threshold for light, they are responsible for daytime vision (photopic vision) and their mission is to detect colors and shapes (details).
Therefore, we can conclude that in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark.

It may lead to bladder infection, difficulty during urination and frequent urination. The treatment of cystocele depends upon its severity.
In case of the older female client the cystocele is causing discomfort and she has already taken the self care measurement by using peripads.
She is managing the disease with the peripads and wants to avoid the surgery.
The nurse should explain the severity of the disease and explain her about how she has managed the disease with self care since last year. The nurse should explain the benefits associated with the surgery and how can she be relaxed in the coming years after surgery.
Progesterone and estrogens are thought responsible for the release (and prevention of release) of an egg during ovulation
