• #1 Astigmatism – Symptoms & causes – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/astigmatism/symptoms-causes/syc-20353835

  Astigmatism occurs when either the front surface of the eye (cornea) or the lens inside the eye has mismatched curves. Instead of having one curve like a round ball, the surface is egg-shaped. This causes blurred vision at all distances. […] Signs and symptoms of astigmatism may include: Blurred or distorted vision, Eyestrain or discomfort, Headaches, Difficulty with night vision, Squinting. […] Astigmatism may be present from birth, or it may develop after an eye injury, disease or surgery. Astigmatism isn’t caused or made worse by reading in poor light, sitting too close to the television or squinting. […] Either type of astigmatism can cause blurred vision. Blurred vision may occur more in one direction: horizontally, vertically or diagonally.

  Common signs and symptoms of astigmatism include: […] Blurred or distorted vision at all distances […] Poor night vision […] Double vision in one or both eyes […] Eyestrain […] Headaches. […] However, some children do not outgrow their astigmatism, and uncorrected astigmatism can negatively impact learning and development. […] A regular astigmatism should be correctable to 20/20, according to the American Academy of Ophthalmology, though an astigmatism may be too severe to correct vision to normal. An irregular astigmatism often cannot be corrected to 20/20. […] Night driving with uncorrected astigmatism can be a tricky task. This is because astigmatism causes light to scatter in the eye rather than focus it on a single point (the retina). Street and traffic lights have distracting glare, halos, or streaks to people with astigmatism. This can have a negative effect on night driving.

  https://www.abckidseyes.com/blog/6-problems-that-are-linked-to-astigmatism

  While almost everyone has some degree of astigmatism, a common eye problem that affects the way light enters your eye, it needs correction in about one-third of the cases. […] Blurry vision is a common symptom of astigmatism, and it happens with farsightedness (hyperopia) and nearsightedness (myopia) too. […] The main difference is that astigmatism blurs your vision all the time, while the other two vision problems only cause blurriness at specific distances. […] Eyestrain develops when your eyes have to work extra hard to see or focus. […] If your child has astigmatism, they may complain of symptoms like: Eye aching or pain, Itching or burning eyes, Sensitivity to light, Eye twitching, Eyes that feel dry or scratchy. […] Your child’s eyes want to see clearly, and when objects are blurry, they work extra hard to focus and create clear images.

• #1 Astigmatism: Causes, Symptoms, and Treatment

  https://patient.info/eye-care/astigmatism

  Astigmatism is a common eye condition that affects the shape of the cornea or the lens of the eye. The main symptom of astigmatism is blurred vision. Vision problems, such as astigmatism, are also known as refractive errors. For most people with astigmatism, it is a very mild, minor problem which may not even be noticed. However, with more advanced astigmatism, there can be a variety of symptoms including: […] Blurred vision. […] Light sensitivity (photophobia). […] Eye strain and fatigue (especially after long periods of concentration, such as when using a computer). […] Headaches. […] Other symptoms can include: […] Difficulty seeing one colour against another (contrast). […] Distorted images, such as lines which lean to one side. […] Double vision (with severe astigmatism).

  https://www.planetlasik.com/blog/early-signs-of-astigmatism-and-how-to-treat-it

  Headaches are a common complaint among individuals with astigmatism. The constant effort to focus and adjust for unclear vision can strain the eye muscles, leading to persistent headaches, particularly after activities requiring prolonged visual concentration. […] Another sign of astigmatism is poor night vision. Individuals often experience glare, halos around lights, and increased sensitivity to bright lights when driving at night. The irregular corneal shape scatters light in multiple directions, making it difficult to focus in low-light conditions. […] Squinting is a natural reflex to improve focus by reducing the amount of light entering the eye. People with astigmatism clinical features may find themselves frequently squinting in an attempt to sharpen their vision. […] In some cases, individuals with astigmatism may experience double vision (diplopia). This symptom occurs when the eye fails to merge light into a single, clear image due to the irregular curvature of the cornea.

• #1 Astigmatism: A closer look at causes, symptoms, treatments

  https://www.acuvue.com/en-us/eye-health/astigmatism/closer-look/

  With astigmatism, your cornea or lens isn’t spherical like most people’s, it’s more cylindrical, like an American football. Since light isn’t passing through a uniform sphere shape, it doesn’t focus equally on one part of your retina (the part of your eye that helps form the images you see), it focuses at two or more points inside the eye. For example, one point might be on the retina and one might be behind the retina. This is what can create blurry or distorted vision. […] People with uncorrected astigmatism may experience one or more of these symptoms, and they can be mild or more severe, depending on the shape of your cornea and/or lens. […] Blurry vision at all distances […] Distorted or squashed images […] Streaky or haloed lights at night […] Headaches […] Eye fatigue […] Squinting […] Difficulty seeing at night. […] Uncorrected astigmatism can present some challenges when encountering bright lights at night.

• #1 Physiology of Astigmatism – EyeWiki

  https://eyewiki.org/Physiology_of_Astigmatism

  Age-related evolution of ocular astigmatism in terms of power and axis has been observed in epidemiologic studies. It is well documented that a high degree of astigmatism is present in neonates and infants; however, the reported amounts show discrepancies. The degree of astigmatism is even higher in preterm newborns and has an inverse association with postconceptional age and birth weight. In near retinoscopy without cycloplegia, Gwiazda and colleagues found astigmatism of at least 1 D in about 55% of infants younger than 5 months, 10% of whom displayed a cylinder power of 3 D or more. In another study, photorefractive techniques showed that almost all infants at the age of 3 months had at least 1 D of astigmatism, which had decreased to adult levels by the age of 18 months. Likewise, a longitudinal study found astigmatism of at least 1 D in about 40% of infants at 3 months of age with a significant decrease to 4% by the age of 36 months. This reduction appears to be caused by the decrease in toricity of the cornea and the anterior lens. Several studies have suggested that corneal shape changes throughout life. The linear reduction of the astigmatism to lower values with age is apparently a part of normal eye maturation and emmetropisation. It has been suggested that the high astigmatism in early life induces and activates accommodation.

• #1 Physiology of Astigmatism – EyeWiki

  https://eyewiki.org/Physiology_of_Astigmatism

  As the child grows older, much of the early astigmatism will gradually disappear and transform into with the rule owing to eyelid pressure. Most of the changes occur at ages 1-3 years, when the vertical and horizontal diameters of the cornea and its elasticity attain adult size and amount. This with-the-rule astigmatism in preschool children is stabilized towards adolescence. However, this is not always true, and a role for myopia development has been attributed to ocular astigmatism, as it may degrade optical blur cues and disrupt emmetropisation, which can lead to axial myopia progression in school-aged children. […] In early adulthood, astigmatism of more than one diopter is infrequent and is still with the rule. Lin and colleagues found a slight increase in the amount of astigmatism in medical students after five years. Other cross-sectional studies have indicated that mean total astigmatism changes with age, varying from as much as 0.62 D with the rule during adolescence to as much as 0.37 D against the rule in older ages. Anterior corneal (and total) astigmatism shows flattening in the vertical meridian with aging, in contrast to a trend towards with-the-rule astigmatism on the posterior corneal surface. Against-the-rule astigmatism is the most common type of astigmatism in adults over 40 years of age. Interestingly, men are significantly more likely to develop against-the-rule astigmatism. In general, corneal toricity accounts for the major component of total astigmatism; it is suggested that, with aging, upper eyelid pressure on the cornea and the tone of orbicularis muscle decrease. It has also been demonstrated that with-the-rule astigmatism decreases when eyelids are retracted from the cornea. When relative steepening in the vertical meridian is abated, the intrinsic lenticular against-the-rule astigmatism will manifest. Decreases in action of extraocular muscles, especially the medial rectus, and vitreous syneresis and liquefaction may also contribute. The contribution of the lens to the ocular astigmatism is relatively constant throughout life. Development of this lenticular astigmatism may be due to an emmetropisation phenomenon, as it effectively decreases manifest astigmatism in the early decades of life. But in older ages, lenticular astigmatism is manifested as an against-the-rule astigmatism when the corneal astigmatism is decreased.

  https://theeyecareteam.com/what-causes-astigmatism-to-worsen/

  Astigmatism can change or worsen over a persons lifetime due to several factors, including age, eye injuries, or conditions like keratoconus. […] Untreated astigmatism can cause eye strain and headaches as the eyes work harder to focus. […] Astigmatism is not always a stable refractive errorits severity can change over time and may also decrease. […] These changes may result from changes in eyelid tension and eye muscles, affecting how light refracts through the eye and potentially worsening astigmatism. […] When the cornea heals irregularly from a scratch, or the lens suffers damage, it can lead to uneven light refraction and alter the degree of astigmatism. […] Keratoconus is a vision disorder that causes the cornea to thin and form a cone shape, significantly distorting light and exacerbating astigmatism.

The mechanical injury from repeatedly rubbing your eye can sort of stretch out the cornea and cause it to lose its strength, he says. […] A small amount of vertical astigmatism (where the vertical curve is not perfectly shaped) may improve or even go away because of the constant pressure on the lids. More pronounced horizontal astigmatism may gradually get worse; it can be corrected with contacts or eyeglasses or treated with surgery, but it won’t go away on its own. […] Astigmatism can worsen and get to the point where glasses no longer correct the vision, in which case the person may need to wear a special hard contact lens, says See.

This will cause near or far images to be blurred. […] When you have an astigmatism, your eyes are working harder than they should to create clear images. This will cause eye strain and your eye muscles will tire easily, resulting in frequent headaches and fatigue. […] If you have an astigmatism, the artificial light from streetlamps and vehicle headlights/taillights will be blurry. This can be especially dangerous since it makes it difficult to anticipate what other vehicles are going to do due to blurry vision. […] Astigmatisms have different levels of severity, and the Vision Eye Group doctors can recommend a treatment option to help eliminate this issue! An accurate diagnosis is the first step toward enjoying everyday activities again without eye issues.

  Headaches are a common complaint among individuals with astigmatism. The constant effort to focus and adjust for unclear vision can strain the eye muscles, leading to persistent headaches, particularly after activities requiring prolonged visual concentration. […] Another sign of astigmatism is poor night vision. Individuals often experience glare, halos around lights, and increased sensitivity to bright lights when driving at night. The irregular corneal shape scatters light in multiple directions, making it difficult to focus in low-light conditions.

People with astigmatism clinical features may find themselves frequently squinting in an attempt to sharpen their vision. […] In some cases, individuals with astigmatism may experience double vision (diplopia). This symptom occurs when the eye fails to merge light into a single, clear image due to the irregular curvature of the cornea.

• #2 Physiology of Astigmatism – EyeWiki

  https://eyewiki.org/Physiology_of_Astigmatism

  As the child grows older, much of the early astigmatism will gradually disappear and transform into with the rule owing to eyelid pressure. Most of the changes occur at ages 1-3 years, when the vertical and horizontal diameters of the cornea and its elasticity attain adult size and amount. This with-the-rule astigmatism in preschool children is stabilized towards adolescence. However, this is not always true, and a role for myopia development has been attributed to ocular astigmatism, as it may degrade optical blur cues and disrupt emmetropisation, which can lead to axial myopia progression in school-aged children. […] In early adulthood, astigmatism of more than one diopter is infrequent and is still with the rule. Lin and colleagues found a slight increase in the amount of astigmatism in medical students after five years. Other cross-sectional studies have indicated that mean total astigmatism changes with age, varying from as much as 0.62 D with the rule during adolescence to as much as 0.37 D against the rule in older ages. Anterior corneal (and total) astigmatism shows flattening in the vertical meridian with aging, in contrast to a trend towards with-the-rule astigmatism on the posterior corneal surface. Against-the-rule astigmatism is the most common type of astigmatism in adults over 40 years of age. Interestingly, men are significantly more likely to develop against-the-rule astigmatism. In general, corneal toricity accounts for the major component of total astigmatism; it is suggested that, with aging, upper eyelid pressure on the cornea and the tone of orbicularis muscle decrease. It has also been demonstrated that with-the-rule astigmatism decreases when eyelids are retracted from the cornea. When relative steepening in the vertical meridian is abated, the intrinsic lenticular against-the-rule astigmatism will manifest. Decreases in action of extraocular muscles, especially the medial rectus, and vitreous syneresis and liquefaction may also contribute. The contribution of the lens to the ocular astigmatism is relatively constant throughout life. Development of this lenticular astigmatism may be due to an emmetropisation phenomenon, as it effectively decreases manifest astigmatism in the early decades of life. But in older ages, lenticular astigmatism is manifested as an against-the-rule astigmatism when the corneal astigmatism is decreased.
