Farsightedness (Definition)

Also referred to as Hyperopia. A short axial length of the eye or a non-optimized lens allows light to focus behind the retina instead of on the retinal plane. This typically results in an inability to ...Read more

One eye is far-sighted and the other is near-sighted. Is this a rare occurence?

See eye doctor: It is not too common. Some people choose elective surgery to create this condition so they do not wear glasses as they use one eye for distance and one eye for near. You may want a pair of glasses to even out the eyes to lessen strain. ...Read more

Refractive error: Is the medical term for nearsightedness, farsightedness or astigmatism. Although more common for both eyes to be similar, it's not that uncommon for you to have different refractive errors between your two eyes. ...Read more

What to do if I had my eye exam the other day, and I have one far-sighted eye, and one near-sighted eye. Just wondering if anyone else has this condition?

What to do if I had my eye exam the other day, and I have one far-sighted eye, and one near-sighted eye. Just wondering if anyone else has this condition?

It can happen: It is not that uncommon to have a situation like yours. While most people do have similar prescriptions in each eye, our bodies are not perfectly symmetrical and differences in arm length, etc. Are common. Your condition can usually be easily managed with the correct eye glass or contact lens prescription. Laser vision correction surgery could also be an option ...Read more

What is it called when one of your eyes is near sighted but the other eye is far sighted?

What is it called when one of your eyes is near sighted but the other eye is far sighted?

Anisometropia: Any big difference in eyeglass power (>2.50) is called anisometropia, and makes it difficult to wear glasses successfully. Often the patient wears contacts. If the difference in near and farsightedness (example r eye -0.50 and l eye +0.50, difference 1.00) is small, then the fact that one is slightly near and the other is slightly far shouldn't bother the patient too much. ...Read more

If nearsightedness is from a too-long eyeball, and farsightedness from too short, what are bifocals benefits?

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

At what avg age does a person become far sighted as he ages? My le -8, 're -9, -1cylindricl in both eyes, m 33 nw bt still my myopia hasn't stabilised yet

At what avg age does a person become far sighted as he ages? My le -8, 're -9, -1cylindricl in both eyes, m 33 nw bt still my myopia hasn't stabilised yet

Normal presbyopia: Becomes noticeable at around age 40 but high myopes get a grace period. There is a chance also that your myopia will reverse. I have patients who are -22 so you are not so bad. Two of our eyemd in my practice are also -9. Best wishes. ...Read more

What is the difference between being near sighted and far sighted?

What is the difference between being near sighted and far sighted?

Location of focus: Near sighted means you see better at near and your distance vision is blurry. Far sighted is just the opposite. In near sighted eyes, the image is brought into focus in front of the retina and a diverging lens is needed to push the image backward to focus on the retina. In a far sighted eye, the image is focused behind the retina and a converging lens is needed to bring the image forward. ...Read more

Is it possible for nearsightedness to become farsightedness?

Is it possible for nearsightedness to become farsightedness?

Yes: Though uncommon, there are ways for someone to change from near to far-sightedness. The most common way is from natural aging (growth of eye) and from cataract development (change in lens power). Other possibilities include laser vision, trauma, corneal scarring, refractive lens exchange, corneal ectasia, and retinal pathology. ...Read more

Help docs! I'm trying to find out what causes nearsightedness/farsightedness?

Imbalance: Nearsightedness and farsightedness are caused by an inappropriate amount of refraction for the particular eye. In nearsightedness, the amount of focusing present is too much for the length of the eye. In farsightedness, it is the opposite. ...Read more

I had laser surgery to correct nearsightedness. Post op, I am slightly far-sighted and have a mild astigmatism. Should I get an enhancement?

I had laser surgery to correct nearsightedness. Post op, I am slightly far-sighted and have a mild astigmatism. Should I get an enhancement?

Maybe: This is a question to discuss with your surgeon. The risk / benefit ratio must be evaluated. What is your current vision versus your visual needs? How long has it been since your surgery? Has your vision stabilized? Are any coexisting conditions like dry eye treated? Can a hyperopic treatment be done under the old flap or must a new, bigger flap be created with additional risk?
Good luck. ...Read more
