Farsightedness: near blur

Do you hardly distinguish certain objects close together, and you feel that you see better off? You may submit a hyperopia, a vision disorder relatively common. What is it? What signs should alert you? How to correct it? Answers.

Hyperopia is a vision defect in which the image tends to form behind the retina rather than on it. Consequently, the lens is forced to accommodate continuously to bring the image in the center of the retina. That is a bit like a photographer.

Hyperopia is particularly common in children. If it is strongly pronounced, it will also tend to “make squint.” Experts speak of “accommodative strabismus type.” A school age it is manifested by headaches, especially at night. These headaches are very characteristic, with a sense of “bar” above the eyelids. That should get your attention, and motivate a consultation.

Glasses, lenses or laser …!

As a teenager, these headaches may persist with the addition, a fluctuating sense of purpose. In adulthood, it can also be associated with early onset (before age 40) of presbyopia. This also corresponds also to a lack of focus of the lens. But this is because with age it loses its flexibility and ability to “bulge” to accommodate.

The correction of hyperopia based on glasses with converging lenses or contact lenses. In both cases, the goal is to allow the image to be formed more forward of the eye, the retina. Since the late 90’s, hyperopia can be corrected with refractive surgery. It then requires the use of laser. “This intervention aims to change the curvature of the cornea by digging a peripheral ring, causing a central bulge,” says the clinic site Sourdille in Nantes. “The duration of the intervention is less than 15 minutes and that of the laser does not exceed a few tens of seconds.” These interventions, however, are only carried out in adults, when the conformation of the eye is no longer subject to change.

For any questions or if your child regularly complains of headaches at night, ask your doctor or ophthalmologist.
