Causes of hyperopia

 

contact lenses for correction of hyperopia

 

As with myopia, the cause of the defect is due to incorrect shape of the eyeball. This is shorter than the ideal curvature. As a result, light rays fall behind the retina instead of directly onto its surface, making the captured image appear blurry. Persons with this disorder often have reading difficulties.

Hyperopia may occur at birth and may be corrected with the progressive growth and development of the child's eyes. Especially young people with low defects may not realize that they are affected by hyperopia. People with high hyperopia may experience blurred vision not only of nearby objects but also of objects at a greater distance. In the elderly, it is necessary to differentiate whether they suffer from refractive error of myopia or whether it is another type of defect called presbyopia (eye defect associated with aging of the body in which the eye lens loses its elasticity and consequently the affected person has difficulty focusing near) .

People with myopia can suffer from headaches and feel tired when working with objects in close proximity. If these symptoms occur even if you are already wearing glasses or contact lenses, you should check with your eye care specialist. It is possible that your current prescription is no longer sufficient and you will need a new one.

 

Ways of correction of hyperopia

 

Hyperopia can be corrected by glasses or contact lenses, which adjust the refraction of light so that it hits the retina correctly. Depending on the severity of the defect, you may need to wear the eyewear every time you need to concentrate on any objects nearby or only occasionally, such as when reading, working with your computer, or performing detailed work.

People with stronger dioptres are advised to choose high-index aspherical lenses that are thinner, lighter and more aesthetic overall. Their disadvantage may be a greater reflection of light than conventional plastic lenses, which, however, can be eliminated by adding an antireflective layer.

Another way to correct this refractive error is to refractive surgery, which can completely eliminate the need to wear glasses or contact lenses.

 

Near vision correction contact lenses are designed to bend light beams inwardly to focus a little closer on the retina.

Lenses designed to correct hyperopia have a dioptric force on the prescription with a plus (+) sign. The stronger the defect, the higher the number. It happens that each eye needs a different level of correction, and therefore the regulations for the right and left eye differ.
