Intermittent fasting - a cure for myopia

by - April 25, 2019


Are you already wondering what relationship intermittent fasting could have with myopia? Or how it can benefit a myopic person?

You'd be surprised how simple things are the most effective.t

Let's start by considering what myopia really is.

Myopia, which is nearsightedness, is the more common cause of impaired vision in people under the age of 40 and is associated with the greatest risk of pathological outcomes.

Myopia is described by focus of light in front of the retina. Therefore, objects close to the eye appear clearly, but those distant from the eye appear blurry. It occurs when an eyeball grows too long or the cornea becomes too steeply curved, the result being that light entering the eye doesn't come to a clear focus point on the retina, which is required for clear vision at all distances.

Globally, research suggests that in the year 2000, roughly 25 percent of the world's population was nearsighted but by the year 2050, it's expected that roughly half the people on the planet will be myopic. If you are nearsighted, you will have difficulty reading road signs and seeing distant objects clearly, but will be able to see well for close-up tasks such as reading and computer use. Other signs and symptoms of myopia include squinting, eye strain and headaches. Feeling fatigued when driving or playing sports also can be a symptom of uncorrected nearsightedness.

The extremely rapid changes in the prevalence of myopia and the dependence of myopia on the level of education indicate that there are very strong environmental impacts on the development of myopia. This conflicts with the common occurrence of familial patterns of inheritance of myopia, which suggests a role for genetic determination.

The importance of myopia as a public health issue is often underestimated because of the ease with which refractive errors can be corrected with glasses or contact lenses, refractive surgery or orthokeratology.
The real public health costs associated with myopia are undoubtedly much higher, for myopia, particularly high myopia, is a major cause of visual impairment and blindness in many countries. Long -term debilitating conditions such as blindness impose extremely high public health costs. These costs are certain to increase, for the prevalence of myopia is increasing in many parts of the world.

The only way to fix myopia is to address the causes. That being said, intermittent fasting can help with some aspects of myopia rehabilitation, if you are already working with reduced prescriptions, getting good breaks from close-up, and getting focal stimulus. Once you have reduced your myopia to either the last diopter (or for high myopes by about half in many cases), things can slow down a bit, this is when intermittent fasting will be most successful.

Also, it has been suggested that changes in diet, specifically the move to high sugar, high processed cereal diets, may have a role in the increasing prevalence of myopia, perhaps by increasing sensitivity to environmental risk factors through an interaction of diet-related insulin-like growth factors with eye growth regulatory processes.

In intermittent fasting, you start to lower your basal insulin level, and start to back off on motor activation, and turn on autophagy which is an intracellular cleaning process (has a lot of benefits in terms of removing damaged proteins). Your brain-derived neurotrophic factor gets a boost, a lot of benefits for the brain, metabolically and hormonally you get a lot of benefits from this.

In one study, Food restriction was used as a strategy to restore plasticity in the adult visual cortex of rats. A short period of food restriction in adulthood is able both to reinstate ocular dominance plasticity, hence, ability for changes to be made.

Let’s look at it simply as this, the ocular system which has been running a normal course, being fed with all necessary nutrients, now having shortages on some days makes the system more active in the search of a balance and alternative sources. It is always at these times that the system recognizes and makes changes to errors in the system  while trying to reach a balance and this includes refractive changes, example, myopia.

As usual, it is the simple things that are most effective.
