The rods are responsible for peripheral vision and are located outside the central part of the retina. They are very numerous – almost 120 million – and are responsible for night vision because they are very sensitive to low-intensity light. In contrast, they become completely blind to high-intensity light and are therefore irrelevant to day vision or visual acuity. Not being able to distinguish colors, they give rise to achromatic vision.
1) An external segment: characterized by a membranous structure (called “disks”), in which are positioned the photopigments that react to photon stimuli (light arriving in “concentrations” called light quanta).

What is the cane and what is it used for?
The cane is a stick that is used to support a person when walking or after an injury without losing balance. … What the cane does is to take weight off your leg and joints.
What is the function of the rods in the eye?
The canes serve: √ Used for peripheral vision and focus on the outer edges of the retina. √ Responsible for our night vision. Rods are necessary for light and dark perception and for adapting to night vision.
How should the cane be used?
Stand with a firm grip on your cane. As you step forward with your weaker leg, swing the cane the same distance in front of you. The tip of the baton and your front foot should be even. Take some of the pressure off your weaker leg by putting pressure on the pole.
The cane is used on the side of the bad leg.
However, these retinal cells perform different functions that allow us to see and have a clear vision during the day and at night. Let’s first explain the function performed by these photoreceptor cells.
Dr. JD Solomon, ophthalmologist and author of Overcoming Macular Degeneration: A Guide to Seeing Beyond the Clouds, says, “…the most important cells in the vision process are the cones and rods.”
There are many more rod photoreceptor cells than cone photoreceptor cells in the retina, especially outside the macula. The human eye contains about 130 million rods and about 7 million cones. The rods are useful:
Did you know that the macula, the center of the retina responsible for our direct vision, is also responsible for our ability to see colors? Thanks to a high concentration of cone cells, colors are vivid and bright.
However, one of the symptoms of macular degeneration is that colors appear faded and less bright. This is the result of the cone cells becoming less functional or less abundant. We find that colors appear duller; it is also more difficult to distinguish colors such as black from navy blue.
Why use a cane?
The poles work the arms, shoulders, chest and upper back muscles through a functional range of motion while walking, which can help turn daily walking into a full-body workout.
Who should use a cane?
The use of a cane is particularly associated with older adults, however it is of utmost importance to learn how to use it to re-educate walking after surgery or leg injury at any age, as the affected limb will need support while it is healing.
What substance is formed in the rods of the retina?
Rhodopsin or retinal purple is a pigment found in certain retinal cells called rods.
Use of the rod
It is a test to measure the electrical response of the light-sensitive cells of the eye, called rods and cones. These cells are part of the retina (the back of the eye). How the test is performed
You should not rub your eyes for 1 hour after the test, as this could injure the cornea. Your provider will talk with you about the test results and what it means for you. Alternative Names: Retinal eye exam – retinal retina

How is the baton used in dance?
The cane lends itself to many games, so the creativity of the dancer also counts a lot. In ancient times the cane was the scepter of the pharaohs. It represents strength, power. So when dancing it, one has to adopt a posture of these characteristics, haughty and at the same time with strength and feminine sensuality.
How should a single crutch be used?
How to walk with a crutch
To start walking, you should bring the crutch forward at the same time as your injured leg, then bring your healthy leg forward while holding the crutch firmly. Remember that your feet should never overtake the crutch and that your stride should be slow and cautious.
Why use trekking poles?
Trekking or hiking poles allow us to rest part of the body, especially if you are equipped with a backpack, on the arms and thus unload the legs. They help us when walking and can improve walking or prevent injuries to the lower limbs.
Types of walking canes
It is important to start walking soon after surgery for a leg injury, but you will need support while your leg is healing. A cane can be used for support. It may be a good choice if you just need a little help with balance and stability or if your leg is just a little weak or sore.The two main types of canes are:Your surgeon or physical therapist will help you choose the type of cane that is best for you. The type of cane you use will depend on how much support you need.Talk to your doctor if you are experiencing a lot of pain, weakness, or balance problems. Crutches or a walker may be better options for you.Cane Basics
