You may have encountered an error code indicating a spherical error in the eyes. Well, there are several ways to solve this problem, which we will discuss shortly. Spherical aberrations occur when the optical power of the eye is clearly either too high, or perhaps too low, to properly focus light on the retina, on the light-sensitive areas lining the inner surface of the eye. Here are examples of spherical errors: – Myopia: Nearsightedness is often referred to as myopia .
|One eye correctly focused ( top), but shows two refractive errors: throughout the center of the image, the light is structured too far forward; at the bottom of the image, the focus is at the back of the eye|

How do you cure spherical vision?
Change the refractive power of the eyes by adding improved lenses as needed. This allows the use of spectacles, contact lenses, implantable straight contact lenses, or even refractive lateral exchange.The change in refractive power is related to the eye’s cornea.Changes in the shape and length of the human eyeball.
A refractive error, also known as a refractive error, is a problem in accurately highlighting light on the retina due to the shape of the skin and/or cornea. The most likely  types of refractive errors are nearsightedness, farsightedness, astigmatism, and presbyopia. Nearby objects are blurry and contribute to astigmatism of objects that appear stretched or blurry. Other symptoms may include blurred vision, shifting from side to side, headaches, and eye strain.
What happens when cornea is not spherical?
Astigmatism occurs when the front surface of the eye (cornea) and the lens inside the eye have incompatible curves. Instead of having a curve defined as a sphere, my surface is oval. This results in an unreadable appearance at all distances.
Myopia can be due to the fact that the whole eyeball is too long, farsightedness is too short, astigmatism, this cornea has a bad shape and therefore presbyopia, aging of the lens, that the eye is notcan form sufficiently.  If certain ametropias occur more frequently in affected patients. Diagnosis is by eyelid examination [ 1]
Is refractive error curable?
Fortunately, echo errors can be handled. However, in order to treat it, your ophthalmologist must first determine how severe ametropia is in large patients.the powers of the people. There are four types of errors: farsightedness refractive errors.
Refractive errors are corrected with reading glasses, contact lenses, or surgery.Glasses are generally the safest and easiest correction method. However, contact lenses can provide a much wider field of view; stores are associated with the risk of infection. surgery Refractive  permanently changes the shape of the cornea.
The number of people with refractive errors worldwide is currently estimated to be between one and several billion. Rates vary by country of destination: approximately 25% of Europeans 80% and Asians are affected.  Myopia is the most common condition. The rate is 15-49% in adults and 1.2-42% in children. Farsightedness most often affects children and the elderly. Presbyopia affects  most of the older relatives under the age of 35. 
The number of people with uncorrected echo errors in 2013 was estimated to be between 660 1,000,000 (10 per 100 people). Of these, 9.5 million were blind. due to a refractive error.  This is expected to be one of the most common points of vision loss in cataracts, leading to macular degeneration and vitamin A deficiency.
An eye that does not have echo aberration when looking at distant objects has documented emmetropia, meaning that the eye is in a state where it can perceive parallel beams of light (the light used by distant objects) on the retina of useless housing. The distant target in this case is defined from the point of view of any object of interest beyond 6 meters or 20 feet, since the light emitted by objects always reaches people in the form of almost parallel beams, given the limitations of human perception.< sup>. ]
What causes refractive errors in the eye?
Refractive errors can be caused by: the length of the eyeball (when my eyeball gets too long or too short) shape problems inside the cornea (the transparent outer surface of the eye) aging of each of our lenses (the inside of the eye is usually clear and also helps the eyes to focus)
The eye has a refractive error whenever you look at distant objects and is called ametropic or ametropic. This eye may or may not be in focus. Direct rays, including light rays from (light from distant objects) parallel to the retina.
The word “ametropia” can be used interchangeably with “abnormality of the word refraction”. Types of ametropia plus myopia farsightedness astigmatism. They are often divided into spherical and cylindrical error defects:
- Spherical Complications occur when the refractive power of the eye is either too high or too low to reach the target on the retina. People with echo defects often have blurry vision.
- Myopia. If the optic is designed too long for the eyeball’s length, you are nearsighted. This must certainly be due to a too curved cornea or lens (refractive myopia) or a too long eyeball (axial myopia). Nearsightedness can be easily corrected with concave lenses, which cause light rays to diverge before they normally reach the cornea.
- Hypermetropia: When the optics are too weak for the length of the eye itself, farsightedness or farsightedness occurs. This may be caused by too little curvature of the cornea or the lensa farsightedness) (refractive or too short eyeball (axial farsightedness).
- Presbyopia: The flexibility of the lens is reduced, usually as with age. A person with this may have difficulty with near vision, which is often relieved by bifocal reading glasses in addition to progressive lenses.
- Cylindrical errors Allowing astigmatism, the power of the eye is too strong or too weak when touching the meridian, for example, when the curvature of the cornea tends to be cylindrical. The angle formed by this meridian and the horizontal is called the axis, usually a cylinder.
- Astigmatism: With astigmatism echo defects, sees lines with a distinct, less defined orientation than lines that are strictly perpendicular to them. This error can be corrected by refracting more light in one meridian than in the other. This function is performed by cylindrical lenses.
