How Long Should Farsightedness Last
If nearsightedness is from a too-long eyeball, and farsightedness from too short, what are bifocals benefits?
Lense changes: The lens of the eye hardens year by year from birth to about age 52 when it becomes a rock. The impact of this in a practical sense starts at age 38-42 when near vision becomes a problem. Bifocals compensate for this hardening of the lens and allow for both near and far vision with one eyeglass. This is independent of the basic power and occurs in all humans/all refractive states of eyes. ...Read more
Yes: Almost all new borns are farsighted but fortunately the lens can compensate for this. Their eyes are too short front to back and that is the definition of farsightedness. As they grow, so does the eye and hopefully the eye length and optics match and as adults they will need nothing. If the eye grows too much, they may become myopic. ...Read more
Optical help: This is a refractive state of the eye in which a magnifying type lens in a spectacle will give you clear focus. It is a little bit misnamed as the natural lens can correct it for a while but when the lens loses its ability to compensate, it will show up. Contact lenses can help also and many are eligible for lasik. Your ophthalmologist can sort this out for you. ...Read moreSee 1 more doctor answer
Depends :-): It could be a complement due to your ability to anticipate the future. Far more likely, you can it means you see things at a distance better than you can see things at close range. Ieither your eyeball is too short and the focal point for light lands behind your retina, or the lens in your eye lacks focusing power. Under 40, may self correct. May be symptomless. It is treatable with corrective. ...Read more
Hyperopia: If the eye from front to back is too short, so that the lens and cornea cannot focus the light inside the eye (too weak), the correction for this is to supply a magnifying lens in the eyeglasses. The lens of a farsighted person behaves like a magnifying glass. Most hyperopia is in young people and they grow out of much of it. It also reappears in people past 40 as the natural lens loses focus. ...Read moreSee 1 more doctor answer
Can't see near: Farsighted eyes are focused far off into the distance. They tend to be small eyes that cannot bring near images into focus on the film layer of the eye (retina). The images would essentially form behind the eye, and one would have to walk backwards to bring the retina to the image. Glasses correct farsightedness by providing extra focus to "bring" the image forward onto the retina. ...Read moreSee 1 more doctor answer
Convex lens: The farsighted (hyperopic) eye is too short. The rays of light entering the eye are not bent sharply enough to converge and form an image on the retina; rather, the image is formed behind the retina. A convex lens (shaped like a magnifying glass) adds some light-bending so the rays are bent more sharply, and the image is formed on the retina. A picture of this is much clearer. ...Read more
