Far-sightedness (or long-sightedness) means having poor near-vision capability. If far-sighted eyes do manage to see near objects clearly, then only under exceptional strain and fatigue. This defect is caused either by the fact that the eyeball is too “short” or that the cornea has too little curve, so that light rays are focused at a point behind the retina.
What are the first signs?
Constant tensed accommodation can cause eye fatigue and headaches, which more often than not will afflict people in the evening hours and after work. Marginal far-sightedness often remains undetected until people reach the age of 35 to 40, since the eye accommodates the shortcoming to produce a sharp image. If the defect is more serious, however, it will often be detected in childhood and will require a corrective measure. A frequent side-effect are cross-eyes.
And what can you do about it?
Far-sightedness is treated using corrective convex (plus) lenses to help focus light more precisely on the retina to form a clear image. Eye fatigue and headaches will disappear
A better focus on the world
In the past, eyeglasses for the far-sighted were unflattering. They were thick and heavy, often making the eyes look much larger than they were. Those days are gone. Glass and polycarbonate lenses can now be fashioned in an aspheric (i.e. flatter) form. And the thickness of the lens can also be adapted to the form provided by the frame, so that these eyeglasses can now be designed to be lightweight, thin and flat.
Eyeglasses are all available with a variety of anti-reflective coatings and speciality tints or photochromic options. If you choose hard-resin lenses, it is advisable to add a scratch-resistant coating.
Contact lenses too provide full visual comfort and a wider field of vision for the far-sighted.
