Farsightedness?
What’s that? Does it say I can see far away but not near or vice versa? Then they have this other name, hyperopia....
The American Optometric Association says farsightedness is a vision condition in which distant objects can be seen clearly, but close ones do not come into proper focus. For more than 90% of farsighted people this is correct. Yet, some can be so farsighted that they can’t see at distance vision either!
Another term for farsightedness is hyperopia, which means over active eyes.. Its origin comes from beyond indicating you can see far away into the beyond.
To be accurate, hyperopia is a condition where our eyes are weak in power making images out of focus the closer they are to our eyes., especially within arm’s length where we read and perform most digital activities. Most think hyperopic eyes are strong. A camera requires a weaker lens for distant views and you can see at distant. The stronger eye myth probably came because most farsighted people do outdoor activities and are physically stronger. They aren’t bookworms.
Sorry, although you may have strong muscles, you have weak eyes!
Yet,why the over active definition? Since your eyes are weak in power, you must rely on the lens power within your eye normally reserved for viewing up close like desk and digital activities. Thus you are over focusing to see better at far distances that you should not need stimulation if your eyes had the higher normal power. Thus, you are over focusing, giving the term hyperopia.(like hyper-eye use).
What Causes Farsightedness?
Like nearsightedness(myopia) most think It is inherited. Not a lot of research has gone into the nurture aspect. The only theory I am aware is disuse or avoidance. If you don’t do much reading and other close work, your eyes aren’t challenged and fall into disuse.

The first theory proposed was inheritance
Before the industrial revolution people read little and performed out door activities like farming, ranching and lumber jacking. Almost everyone was farsighted. During that time people were fascinated with genetics from Gregor Mendel’s discoveries. George Washington Carver was an American who studied genetics also. Since hair color, and eye color were inherited, why not vision conditions? That assump[tion was accepted then and exists today. Since enough research doesn’t exist of an alternative to inheritance like there is in myopia, let’s move forward to treatment.
The shape of the eye is a factor in hyperopia. Farsightedness occurs if your eyeball is too short. Then.your eye can't correctly focus the light that enters it. It makes images fall behind rather than on the retina resulting in a blur. (See the top illustration.) This seems to support the nature (genetic) camp. Yet, let's look a little closer.

What is the typical treatment?
Just like in myopia compensative eyeglasses are given to increase the power of the eyes to give clarity at near vision and for some even at distance. In a 1961 study it was found that 91% of people prescribed glasses became worse within one year.

A.M.Skeffington, the father of Developmental Optometry, asked a question many doctors ignored. It is long known that hyperopic patients can’t tolerate their full prescription The answer, which isn’t the intention of this brochure, was the beginning of developmental optometry.
His question means two things. One, always reduce a farsighted prescriptions (don’t give the full power). Secondly, look at other functions of vision at the same time, especially at near vision. They may play a role in farsightedness, especially in prevention. (Take a peek at lens therapy) We look at teaming, close focusing, vision processing, side vision, and eye movements.Treating those conditions may prevent or reduce the need for stronger and stronger glasses..

Anti-reflection coating and a light blue tint is helpful. The blue-light blocking lenses have not yet been fully investigated. However, for those desiring blue-blocker’s, they’re available..
When selecting eyeglass frames the smaller the frame the less thick the lenses will be.
Rimless frames are usually not a good choice because the edges of the lens (the thinnest part) has to be widened to accommodated the grove for the wire that holds the lens. The same is true for completely rimless where the frame has to attach to the lenses. That then makes the center thicker and heavier as well as somewhat unsightly.
