How does it manifest itself??
With the blurred vision of far away objects, but most of all of those at close distance. In the case of slight hypermetropy, one can see correctly in the distance but at the expense of strain and visual fatigue.
Definition
Hypermetropy is the condition of an eye in which, when the accomodation is relaxed, the image of a point at infinity is projected behind the retina as shown below.

Causes
Hypermetropy may be caused by a axially too-short eye while the refraction is normal, or by insufficient refraction. It does not only exist when the dioptric power is low or the eye is too short, but because the refractive power is low for this length or the length is insufficient for this refactive power. The real emmetropy is so rare that, excluding those cases in which a myopia is already diagnosed, practically all other eyes are to be considered hypermetropic. In a next post I will explain the axial hypermetropy and that of curvature.
Which lenses to chose?
The lenses which correct hypermetropy are positive and convergent thus bringing the focus of the image back on the retina. These lenses are thicker at the center than at the sides. Today, thanks to today’s design and construction material, very thin and flat lenses are available which are also very light.

Cateratta is the world’s first cause of blindness. It is always being associated with age, but the accelerating factors and the development of cateratta are, without doubt, exposure to the sun and UV rays. Prolongued exposure to the sun, besides an aging of the eyelids, can be especially harmful in this area and facilitate the appearance of carcinoma. Our face is continuously exposed to light, not only in summer, and the skin around the eye is particularly thin and delicate.
