A refractive error is when the lens of the eye does not properly focus light to form a clear image on the retina, resulting in blurred vision. Myopia, farsightedness, and astigmatism are the three most common refractive errors that affect hundreds of millions of people worldwide.
Myopia. Myopia, also known as myopia, is a refractive error in which the eye is too curved, allowing light rays to focus in front of the retina, resulting in a difficult view of distant objects. Myopia has a genetic component and may also be related to long-term near eye use. Modern people use electronic products for a long time, such as mobile phones, computers, etc., which leads to long-term tension in the eye muscles, which aggravates the incidence of myopia. Symptoms of myopia include eye strain, headache, dry eyes, etc., and severe myopia can also lead to complications such as retinal detachment and glaucoma.
Farsightedness. Hyperopia, also known as hyperopia, is when the eye is too flat, causing light rays to focus behind the retina, resulting in poor visibility of near objects. There is also a genetic component to farsightedness, but it can also be age-related, as the elasticity of the eyeball decreases as we age, leading to the exacerbation of farsightedness. Symptoms of farsightedness include eye strain, headache, dry eyes, eye discomfort, etc., and severe hyperopia can also lead to complications such as strabismus and amblyopia.
Astigmatism. Astigmatism is when the anterior and posterior axes of the eye are inconsistent, making it impossible for light to focus into a clear image. Symptoms of astigmatism include blurred vision, eye strain, headaches, and severe astigmatism can also affect learning and productivity.
*Methods of refractive errors include wearing glasses, glasses, orthokeratology lenses, laser surgery, etc. Wearing glasses is one of the most common** methods, and lenses with different powers are formulated according to the degree of nearsightedness and farsightedness of the eye. Glasses are a more convenient and aesthetically pleasing method, but you need to pay attention to cleaning and use time. Orthokeratology lenses are a popular method in recent years, which shapes the cornea by wearing special lenses while sleeping to achieve the effect of correcting vision. Laser surgery is a minimally invasive method that uses a laser to change the shape of the cornea to correct vision.
In addition to **, prevention is also very important. Myopia caused by long-term use of electronic products can be prevented by controlling the time of use and doing more outdoor activities. Maintaining good eye habits, such as staying away from bright lights and avoiding reading for long periods of time, can also effectively prevent refractive errors from occurring.
In conclusion, refractive errors are one of the eye problems that affect hundreds of millions of people worldwide, and both prevention and prevention are very important. Mastering the correct eye habits and choosing the appropriate method can effectively prevent and improve refractive errors and protect eye health.
