Astigmatism is usually inherited. It may also due to environmental factors such as reading habit and inadequate lighting. Choosing a fluorescent tube or light bulb has no effect on the formation of astigmatism, and the reflection of the blackboard in the classroom will not cause astigmatism.
What causes astigmatism? Astigmatism happens when your cornea or lens has a different shape than normal. The shape makes light bend differently as it enters your eye, causing a refractive error. Doctors don't know what causes astigmatism, and there's no way to prevent it.
Astigmatism is usually caused by your cornea having an irregular shape. Eye care specialists call this corneal astigmatism. You can also have lenticular astigmatism, where the lens in your eye has an irregular shape. Lenticular astigmatism is often caused by cataracts.
Circulatory issues caused by stress and tension are as well as causes of astigmatism. In this case, an accumulation of stress and tension in the neck muscles can lead to a restriction of blood flow to the head and eyes.
The risk of astigmatism increased with both the total years of exposure and the average daily duration of screen exposure.
Overuse of Electronic Devices: The excessive use of smartphones, tablets, computers, and other electronic devices could lead to astigmatism, as well as dry eye. Improper Light Levels: Watching TV or using electronic screens in the dark can cause eye strain and eye fatigue and possibly be a cause for astigmatism.
Vision problems such as astigmatism or farsightedness can exacerbate the effects of viewing digital devices.
By doing astigmatism eye exercises every day, you can improve poor vision due to astigmatism. You don't need to resort to eye surgery or surrender to a lifetime of eyeglasses. There are natural and easy ways to repair your vision yourself. Practice these eye exercises and a few more, and take a daily eye vitamin.
Blurry eyes at night
You are tired so your visual system is fatigued. You have a refractive error such as long-sightedness or astigmatism. During the day, you may be able to compensate for these, but when your eyes are tired, your vision can go blurry. You could be mildly short-sighted.
Avoid glare on TV and computer screens. Place your TV or computer screen where lights do not reflect on the screen. Some people find it easier to work on a computer in a dimly lit room. Special non-glare screens that fit over the computer screen also may help.
Astigmatism frequently worsens with age. Your cornea can become more irregular due to pressure from your eyelids as they lose muscle tone. Astigmatism generally stays stable until your turn 50. After then, your lens curvature progressively worsens each decade.
Because high blood sugar levels can cause the lens to change shape, lenticular astigmatism is a common complication in people with diabetes.
Astigmatism is common in infants and often clears up on its own by the time a child is one year old. Children with myopia (nearsightedness) or hyperopia (farsightedness) are more likely to have astigmatism. Astigmatism affects Hispanic children at higher rates than other children.
Many people with astigmatism need glasses or contact lenses to see clearly, but if you want to cure your astigmatism, either LASIK (laser-assisted in situ keratomileusis) or PRK (photorefractive keratectomy) can correct your vision.
Like eyeglasses, contact lenses can correct most astigmatism. They are available in a variety of types and styles. Contact lenses are also used in a procedure called orthokeratology. In orthokeratology, rigid contact lenses are worn during the night while sleeping until the curvature of the eye evens out.
Astigmatism will not go away on its own. It will either stay the same or get worse with age. While this reality can seem daunting, the good news is that it can be easily corrected.
Yes, you can develop astigmatism as you get older. A study showed that 1 in 4 people between 25 and 59 years old had astigmatism. But in people over the age of 60, that number doubles to 1 in 2 people. This happens because the shape of the cornea and lens can change as you age.
Most cases of astigmatism are hereditary and appear at birth. For some people, the condition can develop later in life. Eye injuries or surgeries may also cause astigmatism due to corneal damage. Vision problems due to astigmatism can get worse as time goes on.
Some of the best nutrients to add to your diet if you have astigmatism are zinc, magnesium, and calcium. You can get high servings of zinc by eating lima beans, oysters, and poultry. Magnesium is found in pumpkin seeds, soybeans, black beans, sunflower seeds, and halibut.
Many people believe that astigmatism is only can be corrected by medical intervention when it can easily be alleviated and even corrected through eye training exercises. In fact, there have been cases where with the right exercises in the right frequency yielded considerable results in just one day!
Glasses or soft contacts cannot usually correct irregular astigmatism completely, but customized contacts can usually overcome this problem. Rigid gas permeable or scleral contact lenses can correct irregular astigmatism and they may be able to get the eye back to 20/20.
Blue light blocking lenses
In fact, excessive screen time can even cause digital eye strain, particularly for those with uncorrected astigmatism. Fortunately, blue light blocking lenses can alleviate this discomfort, and make working on your laptop or texting on your phone much more enjoyable.
Astigmatism, a refractive error in which visual images do not evenly focus on the retina, modulates visual perception, and the accompanying neural processes in the brain.
