Farsighted glasses for vision correction

Farsighted glasses refer to prescription eyeglasses that are used to correct farsightedness. While most people know this obvious fact, many of us do not know exactly what is farsightedness. Also called hyperopia, farsightedness is one of the three visual refractive errors occurring on different people. The other two are nearsightedness and astigmatism. These three conditions along with presbyopia are affecting numerous individuals around the world. And there are statistics showing that myopic patients account for one third of the world’s population, while hyperopia affects a fourth of the world’s population. To some extent, farsightedness and nearsightedness are opposite to each other in terms of symptoms and reasons. While myopia causes people to experience difficulty in seeing distance objects, hyperopia makes it difficulty in viewing close-up things.

When it comes to peripheral symptoms, these two conditions are similar that they both cause headaches and eye strain. Individuals with any of these two problems may squint and feel fatigued in the eyes. Farsighted glasses are the most common solution to farsightedness. These eyeglasses are made with Rx lenses which are the key part of giving vision correction. A farsighted person has eyes that are too short than regular. This makes the light rays entering their eyes focus behind the retina, when clear vision is impossible. Hyperopia eyeglasses take use special lenses with specific powers can help the light rays artificially focus properly and directly on the retina. In this way, the irregular eyeball will be “corrected” and normal vision is “restored”.

Some people may think that farsighted glasses are really magic and powerful. In fact, this corrective effect brought by prescription lenses is only temporary. Once the glasses are removed, it is still impossible for hyperopic patients to see clearly. And another solution called prescription contact lenses can bring similar treatment. The use of transparent contacts only masks the fact that a person needs vision correction. Fortunately, there are permanent treatments. Refractive eye surgeries such as LASIK, CK and PRK can reduce or eliminate the need to wear prescription eyeglasses and contact lenses.
