Posture and Its Effect on Vision
Most people are aware that having bad posture could lead to physical problems later on. What you do not know is that posture can affect your vision.
Forward Head Posture
Based on Program for Better Vision, studies conducted reveal that postural imbalances
are highly associated with poor vision. If you are sitting in front of the computer all day
and you no longer have a perfect 20/20 vision, chances are your posture has affected
your visual acuity more than the computer screen. In relation to this, your daily work
routine could have led to your development of forward head posture.
Before the age of technology dawned on human civilization, people walk with their ears
positioned directly on top of their shoulders. With computers as the primary workstation,
many people have adopted a posture where the ears are forward the shoulder, known
as the forward head posture.
When you unconsciously assume the forward head posture, the head adds 4.5 kgs in
weight for each inch it sits forward from the shoulders. The body has to adjust to this
imbalance by forcing the upper back and neck muscles to work double time to stop the
head from falling onto your upper body. As a result, pressure on the nerves at the
foundation of the skull is increased.
Exactly how does this posture affect vision? When the photo-receptor cells in your eyes
are stimulated by light, the signal is transmitted from the optic nerve to the visual cortex,
where the information is interpreted. The processed signal is then forwarded to the
spinal cord and to the rest of the body.
If you have a slouched posture, the connections between your eyes and the rest of the
body are affected and over time, the condition can lead to decreased circulation,
fatigue, and blurred vision. When vision has been affected by postural imbalances, the
condition can be aggravated by moving the neck forward to clearly see a distant object.
Before you know it, you already have the worst eyesight compounded by your poor
Nowadays, forward head posture is a condition that affects more than 66 percent of the
population. Other than blurred vision, the imbalance can lead to headache and mental
Being responsible for your posture is the first step to healing. When standing up, make
sure that your weight is evenly distributed. In this position, you avoid unconsciously
slouching. On the other hand, when sitting down, position a part of your buttocks close
to the chair’s backrest to keep your body upright.
People may think that posture has nothing to do with blurred eyesight. However, studies
suggest that postural imbalances are linked to poor vision. As most of your time is spent
solving company problems in front of the computer, you are most likely to develop
forward head posture. This condition can gradually damage synaptic connections
between the eyes and the rest of the body, leading to poor vision. So stop blaming the
computers and take full responsibility of your posture now.
