Presbyopia

1 Learn

RosarioWhat is Presbyopia?

Commonly arising between the ages of 45 and 60, presbyopia is the eye condition in which the lens loses its plasticity and the ciliary muscles become weak. This prevents the ciliary muscles from fully contracting while trying to focus the eye’s lens on a nearby object.

Therefore, close objects cannot be refracted effectively and the image is focused behind the retina, causing the image to be blurry. The other two parts of clear close vision, closing of the pupil and convergence of the eyes (looking inwards) also can become weak, adding to the difficulty in seeing close objects.

Understanding

How the eye works

The eyeball consists of three layers: sclera, choroid and retina.

1. The sclera is the thick outer layer of the eye, 4/5th of which is white and the rest is transparent. This transparent area, known as the cornea, allows light to enter the eye and is the the first stage of refraction (bending of light rays).

2. The choroid layer contains blood vessels designed to nourish the retina. The anterior (front) part is modified to form the iris. This is the coloured part of the eye, which has two sets of smooth muscles: radial and circular. The radial fibers which are responsible for dilation allow more light to enter the eye. The circular fibers which are responsible for constriction, let in less light and sharpen the image.

Another modified function of the choroid layer is the cillary body muscle that surrounds the edge of the lens, connected to the lens by suspensory ligaments. In a process known as accommodation, the lens is rounded when the cillary muscle contracts and flattens when it relaxes, enabling the eye to focus on objects at different distances.
Elizabeth, Maryland 23. The retina lines 2/3rd’s of the innermost layer of the eye. It contains the essential cells responsible for converting light rays into electrical signals (phototransduction) which are then sent to the brain for processing. These cells are known as photoreceptors and can be divided into rods and cones.

Each eye roughly contains 6 million cones, found mostly in the centre of the retina. This central area is otherwise know as the macula and allows us to see colour and fine detail. In our periphery we have 120 million rods, which are responsible for seeing movement and dim light.

The electrical signal created by phototransduction is sent via the optic nerve to the thalamus where unnecessary information is discarded.  It is then sent to the visual cortex located in the occipital lobe for initial processing, before being sent to other areas of the brain. The two separate images from each eye are not identical and are put together to create one single fused image, otherwise known as binocular vision.

Margarida 1Vision Exercises

  • Near and Far Eye Exercise

    Alternating between looking near and far will help re-strengthen the ciliary muscles and bring placidity back to the lens.

  • Palming Eye Exercise

    This eye exercise is essential to vision improvement, as it rests and relaxes the eyes. It achieves this through allowing the optic nerve and retina to completely rest from any external light or activity. The palms touching your eye orbits also brings healing attention and energy to the eyes.

  • Presbyopia Chart Eye Exercise

    This eye exercise engages accommodation (contraction of the ciliary muscles to focus on a nearby object) by working the convergence muscles on the inside of the eyeballs. This will strengthen convergence and accommodation as well as bring flexibility back to the lens.

  • Sunning Eye Exercise

    The Sunning eye exercise accomplishes several important, related things. It reduces light sensitivity and thereby reduces the tendency to squint in bright light. It also causes the pupils to fully contract thereby creating sharper vision. At the same time this eye exercise stimulates the macula. Since the macula needs bright light to become fully active, the macula is underutilized if our eyes are not exposed to sunlight.

Movement Exercises

  • Head Rotations

  • Shoulder Rotations

    Rotating the head and shoulders loosens your joints and relaxes the surrounding muscles, allowing more blood flow to the head and eyes. This increased blood flow brings more nourishment to the eyes, helps with the removal of waste and strengthens the vessels in the eye. This exercise improves eyesight by bringing better blood flow to the eyes.

Massage TechniquesBarbara, UK

  • Head Massage

  • Neck Massage

  • Face Massage

    Many people are surprised to hear that massage can improve eyesight. Massage brings more blood flow to the head. It also helps reduce the muscle tension created by using the facial muscles to see more clearly. This tension causes strain and reduced blood flow to the eyes. Reducing strain and increasing blood flow lead to better vision.

Mind Exercises

  • Breaking the Habit of Glasses

    Although glasses are a quick fix for making the world around you clearer, they also promote poor vision habits and create a large amount of eyestrain. This causes a slow deterioration of vision and an unnatural dependency on glasses. Furthermore, corrective lenses for farsightedness (hyperopia) and presbyopia concentrate the light unnaturally on the macula, potentially leading to damage. Besides, don’t we all really want to get rid of our glasses?

  • William Fuller shifting eye exercise with chartsKeeping a Vision Journal

    The process of improving eyesight can be slow at times and improvements can easily be forgotten; journaling helps motivation and keeps you on track. The journal also creates a place where you can write about thoughts and feelings.

  • Relaxation

    Our eyesight is clearer when the eyes and the whole visual system are deeply relaxed. Unfortunately relaxation of the eyes is uncommon these days. This creates  eyestrain and leads to poor visual function. We need to take time to relax our eyes to provide the optimum environment for their good use.
