BLURRED VISION AFTER EXERCISE, POOR EYESIGHT, CAUSES, AND TREATMENT
Why do I get blurred vision after exercise?
In simple terms, the possibility could range from exercising on an empty stomach to nutritional deficiencies, even a serious underlying health problem.
Our ability to see the world, to see it clearly, makes life worth living (or so, I think). Generally speaking, humans do not have eyesight as sharp as those of animals like the eagle.
But at least, our eyesight serves us enough to conduct our daily activities and to see the beauty around us. In this day and age, eyesight problems have become so rampant in the modern world. This, of course, is for some different reasons.
Eye defects are very much related to lifestyle, genetics and some are associated with the long-term effect of some chronic diseases that have become common these days. In a nutshell, the causes of bad eyesight vary.
It may be a problem with the way the light around us is bent, a deterioration of the light-sensitive eye tissue or a problem with the amount of light that can enter the eye.
How do our eyes work?
There is a set of events that take place to allow our eyes to see:
- A beam of light enters the eye through the cornea, which is transparent.
- The cornea then partially bends this light through the pupil.
- The bent light then passes through the front chamber of the eye which is filled with a fluid (aqueous humor).
- The light then passes through the lens located within the eyeball, this lens further bends the light
- The light rays exit the lens and pass through the vitreous humor in the eyeball.
- From there, they reach and strike the retina which is the most sensitive area of the eye.
- The retina is layered specialized cells that convert the light into nerve signals which are sent to the brain for interpretation.
- The brain interprets these generated signals which manifest as vision.
Now that we have seen how our eyes really work, any defect in any of the steps listed above results in bad eyesight.
Bad eyesight -Why do I get blurred vision after exercise?
Though the causes of bad eyesight vary based on the part of the eye that is affected, the problem sometimes lies with the nerves that carry signals between the eye and the brain. The most common problems are associated with refractive errors of the eye incorrectly bending light rays.
Simply put, this means that the cornea and/or lens is not bending the light correctly. Then there are other lens problems where the light is unable to pass through the lens. Other problems may include a build-up of fluids in the anterior chamber of the eye leading to nerve damage or deterioration of the retina.
The most common symptom of these problems is a blurred vision but an affected person may also experience dull or cloudy vision, tunnel vision, glare or halos around lights and in severe cases even blindness. The exact cause of each type of eyesight problem is not always known although it is highly determined by genetics and lifestyle or an interplay of several factors. Here are a few common eye defects:
Short or nearsightedness/ Myopia
I had to start with this because it is the eye defect that I have. It simply means that one is unable to clearly see distant objects but nearby objects are still clear. It is worse when people seem to feel you saw them but just chose not to say hello… Here the cornea is too curved or the eyeball is too long for the lens to focus a clear image on the retina. Myopia can be treated by wearing corrective eyeglasses or contact lenses or eye surgery.
Long of farsightedness/ Hyperopia
This is when distant objects can be seen clearly but the eyes cannot focus properly on nearby objects or doing so causes a headache, unusual eye strain and fatigue.
Like myopia, hyperopia can be corrected by wearing corrective eyeglasses or contact lenses or eye surgery.
This is a type of refractive error which is due to the cornea having an uneven curvature. The lens is unable to change shape to accommodate for all variations in the amount of light reaching various parts of the cornea and the resultant vision is blurred.
Some people may also have difficulties in seeing certain colors or they may experience double vision. It can be corrected as above.
There are a handful of other eye defects not discussed here.
Top activities that ruin eyesight and affect vision clarity
Bright sunlight or light reflection to the eyes
The destructive effect of the UV rays in the sun irritates the eyes. Any form of uncomfortably bright light on the eyes results in blurry eye vision. Sunglasses and face caps and umbrellas…just anything that shields the eyes when one is going to walk in sunlight is highly recommended.
Eye makeup and application brushes can cause bacteria to accumulate in the eyes which can cause infections of the glands in the eyelids, as well as mild to severe eye irritation and infections such as pinkeye and conjunctivitis. The rule of thumb is to avoid any eye makeup when one is suffering any eye infections or irritation. Under normal circumstances, keep eye makeup applicators and brushes clean with a monthly washing with soap and water.
Excessive near focusing, the tv, phone or any form of digital screen, creates unnatural stress on the eyes. Some people wear corrective eye lenses of the wrong power not corresponding to their peculiar eye defects. These can produce headaches, eye malaise, inconsistent vision and red uncomfortable eyes. To reduce strain, our eye doctors recommend following the 20/20/20 rule – every 20 minutes look at least 20 feet away for at least 20 seconds.
Not resting the eyes, reading in poor lighting and insufficient sleep causes dry eyes and eye spasms. At least 6-7 hours of sleep is recommended as the bare minimum to maintain optimum clarity of vision.
Poor Eyeglass and Contact lens Prescriptions
As I earlier mentioned, some people wear corrective eye lenses of the wrong power not corresponding to their peculiar eye defects. Frequent eye exams are highly recommended to ensure precise prescriptions for the demands of the eye.
