Lhypermetropy is a common visual disorder that affects many people around the world. This condition, characterized by difficulty in seeing objects closely, often raises the question of its reversibility. Can we hope that hypermetropy disappears over time? This article explores this issue in detail, focusing on the different stages of life and treatment possibilities.
Understanding hypermetropy
Hypermetropy, or hyperopia, is an anomaly of eye refraction where images of close objects form behind the retina instead of forming directly on the retina. This results in a blurred vision of close objects and, in severe cases, distant objects as well.
This condition is usually caused by a short eyeball or insufficient curvature of the lens or cornea. The hypermetropic eye must then make an additional effort to accommodate and make the image clear, which can lead to eye fatigue and headache.
Hypertropy in children
In children, hypermetropy is often present at birth. This is called physiological hypermetropy. The eyeball of children continues to grow and grow over the years, which can result in a natural correction of this mild hypermetropy.
In most cases, hypermetropy in children is mild and does not require optical correction. However, regular surveillance by a visual health professional is essential to ensure that the child's vision develops properly and to avoid complications such as strabism or ambleopia.
It is important to note that if hypermetropy is strong, it will not usually disappear spontaneously with child growth. In these cases, glasses or contact lenses may be required to correct the vision.
Hypertropy in adulthood
If hypermetropy does not disappear during childhood, it will persist throughout life. In adults, this visual disorder may remain stable or change slightly. However, it is important to distinguish hypermetropy from presbytery, another vision disorder that occurs with age.
The Presbytery is a age-related condition that usually occurs from the age of 40. It is caused by the decreased accommodative power of the eye due to rigidification of the lens. Gycosaminoglycans and collagen fibers sieve, and the lens loses hydration, reducing its flexibility. This loss of flexibility prevents the eye from focusing properly on close objects.
It is important to understand that presbytery is not a direct consequence of hypermetropy, but both conditions may coexist. A hypermetropic person can also become presbyterate with age, which can further complicate his or her vision.
Treatment of hypermetropy
Optical correction
Glasses and contact lenses are the most common methods for correcting hypermetropy. They compensate for insufficient refraction of the eye by helping to focus images directly on the retina. Convex lenses are used to correct hypermetropy by increasing the convergence of light entering the eye.
Contact lenses offer a convenient alternative to glasses, especially for people with mild to moderate hypermetropy. They are placed directly on the cornea and correct the vision discreetly.
Refractive surgery
For those who wish to free themselves from glasses or contact lenses, the refractive surgery is an option. Several types of refractive surgery can correct hypermetropy, including LASIK, PRK and intraocular lens implants.
Refractive surgery involves changing the shape of the cornea to improve the focus of light on the retina. LASIK (Laser-Assisted in Situ Keratomileusis) is one of the most common procedures, where a laser is used to reshape the cornea. The PRK (Photorefractive Keratecomy) is an alternative where the cornea surface is remodeled without creating a corneal shutter.
Intraocular lens implants are another option for people with severe hypermetropy or those who are not good candidates for LASIK or PRK. These lenses are inserted into the eye to correct the vision.
Prevent progression of hypermetropy
Although hypermetropy cannot always be avoided, some measures can help prevent its progression. Here are some tips to maintain good eye health:
- Regular sight examinations : Regular visual examination by a visual health professional detects and corrects vision problems as soon as they appear.
- Visual hygiene Adopting good visual practices, such as avoiding fixing screens for long periods without pause and reading in good lighting conditions, can reduce eye fatigue.
- Food : A diet rich in nutrients beneficial to the eyes, such as omega-3, vitamins A and C, and antioxidants, can contribute to eye health.
- UV protection Wearing sunglasses that block UV rays can protect your eyes from sun damage.
Hypermetropy can disappear naturally in children through eye growth and development. However, hypermetropy persists after childhood is generally permanent. Hypermetropic adults often need optical corrections or refractive surgery to improve their vision.
It is essential to consult a visual health professional regularly to follow the evolution of your vision and adjust your correction if necessary. By adopting good eye care habits and taking appropriate measures, you can effectively manage hypermetropy and maintain a clear and comfortable vision throughout your life.
