You can make your ciliary muscles stronger by focusing on exercises which involve the shifting of your gaze between near objects and far objects as well as doing eye rolling and blinking exercises which help to improve the ciliary muscles ability to focus and also relax and reduce eye strain.
To make your ciliary muscles stronger with near and far focusing, start by holding a near object such as your thumb 10 inches from your face and focus on it.
Then shift your focus to a distant object such as a window or wall for a couple of seconds and then repeat this again by alternating your focus for several minutes.
To make your ciliary muscles strong by doing eye rolling, roll your eyes gently in a circular motion "clockwise and then counterclockwise, doing this helps to improve blood circulation to your eyes and can also relieve tension.
Blinking breaks can also help make your ciliary muscles stronger.
Take some short breaks and blink regularly, especially during extended screen time as this also helps keep the eyes moist and reduce eye strain.
Another exercise for strengthening your ciliary muscles is the finger 8 exercise.
Imagine a large figure 8 and trace it with your eyes and keep your head still.
Or you can also do the 20-20-20 rule by looking at something that's 20 feet away every 20 minutes for 20 seconds.
If the ciliary muscles are weakened it causes difficulty in focusing on objects at various distances and most specifically at near distances.
When the ciliary muscles are weakened it can result in presbyopia as well as the age related loss of accommodation ability and require corrective lenses to see things clearly at a close range.
If the ciliary muscles do not work properly then you may experience blurry vision, and most particularly blurry vision at near distances.
And if the ciliary muscles don't work properly you can also have difficulty in focusing on objects that are close up which is often associated with presbyopia, which is a condition that affects your eye's ability to accommodate or change shape and to focus on near objects.
When the ciliary muscle is relaxed the suspensory ligament is taut and the tautness pulls on the edges of the lens and makes it flatter and less convex.
As a result the change in lens shape allows the eye to focus on distant objects.
What happens to the lens when the ciliary muscles contract is the lens becomes more spherical and has increased focusing power due to a lessening of tension on your zonular fibers.
When your ciliary muscles relax, the fibers become taut and pulls the lens out into a flatter shape, which has less focusing power.
The ciliary muscles pull on the suspensory ligaments "zonules" which hold the lens in place and this contraction causes the lens to become more spherical and increases the curvature.
The contraction of the ciliary muscles also cause the center of the lens to thicken and this further increases the lenses focusing power.
The situation that results in the lens of the eye having a more rounded shape is the contraction of your ciliary muscles that relax the suspensory ligaments which support the lens and allow it to become more spherical and increase it's refractive power.
This process is called accommodation and the eye lens becomes more rounded and thicker when focusing on near objects.
Astigmatism also makes the shape of your eye more curved that it should be and causes blurred vision at all distances.
And in a condition called keratoconus, the cornea thins and then gradually bulges outwards into a cone shape and can also cause blurry and distorted vision.
The shape of your eye lens changes as a result of the contraction and relaxation of the ciliary muscles.
The ciliary muscles are attached to your suspenzory zonules which in turn connect to the eye lens.
And when the ciliary muscles contract, the zonules relax and allow the lens of the eye to become more rounded and increase it's refractive power.
And when the ciliary muscles relax, the zonules tighten, pulling the lens of the eye flatter and decreases it's refractive power.
The process is called accommodation and allows your eye to focus on objects at different distances.
