Myopia – Causes, Symptoms and Treatments

Myopia – Causes, Symptoms and Treatments is  characterized by poor distance vision. Furthermore, this is due to a defect in the convergence of light rays, which causes the image of distant objects to form in front of the retina, instead of on the retina itself. This causes distant objects to be seen out of focus, while nearby objects appear normal. Among other possible symptoms such as headaches and asthenopia. Severe myopia increases the risk of retinal detachment, cataracts and glaucoma .

Myopia is a type of refractive error. The underlying cause is believed to be a combination of genetic and/or environmental factors. Risk factors include work that involves close objects, longer stays indoors, and a family history of the disease.

Myopia is also associated with higher socioeconomic classes. The underlying mechanism involves an excessive length of the eyeball or, less commonly, an overpowering lens. The diagnosis is made by eye examination. So, check now  Myopia – Causes, Symptoms and Treatments.

Myopia Symptoms:

• Blurred vision when looking at distant objects.
• The need to squint or partially close the eyelids to see clearly.
• Headaches caused by excessive eyestrain .
• Difficulty driving a vehicle, especially at night.

Myopia is often first detected during childhood and is commonly diagnosed between school years. A child with myopia can. Present strabismus. Needing to sit closer to the television, movie screen, or in front of the classroom, Holds books too close while reading, Seems to be unaware of distant objects, Blinks excessively, Rubs eyes frequently.

Myopia Treatment:  The goal of myopia treatment is to help focus light correctly on the retina through the use of corrective lenses or refractive surgery.

Corrective Lenses: Wearing corrective lenses treats myopia by counteracting the increase in curvature of your cornea. Types of corrective lenses include.

• Glasses.
• Contact lenses.
• Refractive surgery.

This Treatment Corrects Myopia by Reshaping the Curvature of Your Cornea: Refractive surgery methods include.

• LASIK surgery.
• LASEK Surgery.
• PRK surgery.

Intraocular Lens Implantation:  All surgeries have some degree of risk; Possible complications from these eye procedures include infection, corneal scarring, blurred vision, vision loss, and visual aberrations such as seeing circles around lights at night. Discuss potential risks with your doctor.

Causes of Myopia:  Myopia can occur when the cornea is curved too much or, more commonly, when the eye is longer than normal. Instead of being focused right on the retina, the light is focused in front of it, resulting in a blurry appearance for distant objects.

• The cornea, the clear front surface of the eye .
• The lens, a clear structure inside your eye that changes shape to help focus objects.
• In a perfectly shaped eye , each of these focusing elements has a smooth curvature, like the surface of a sphere. The cornea or lens with such surface curves of
• curvature refracts all incoming light in the same way and makes a perfectly focused image at the back of the eye .
• However, if your cornea or lens is not uniform and curved, the light rays are not refracted correctly, and the image is not evenly focused. This causes vision to appear blurry, giving rise to myopia .
