Doctors are notorious for using complicated terms for simple conditions. For instance, the de facto medical term for a bloody cough is hemoptysis. Eye doctors are, of course, no exception to this rule. Farsightedness is clinically referred to as hyperopia. That being said, many people \u2014 including some eye doctors \u2014 use the term farsightedness instead due to the fact that it\u2019s far easier to remember.<\/p>\n\n\n\n

There are quite a few things that could lead to farsightedness. Some of these causes are present since birth while others may happen throughout your life. Knowing about the various causes will help you detect the problem early and thus get more effective treatment. Being aware also helps you prevent hyperopia since you\u2019ll be able to avoid some of the risk factors for this condition. Without further adieu, here are eight known causes of farsightedness.<\/p>\n\n\n\n

1. Axenfeld-Rieger syndrome<\/h3>\n\n\n\n

Axenfeld-Rieger isn\u2019t one condition but rather a group of conditions. The eye is the most commonly affected area in patients with Axenfeld-Rieger syndrome, but other regions of your body can also be impacted by it. For instance, some patients who suffer from Axenfeld-Rieger syndrome tend to have fewer teeth than normal. The teeth may also be smaller than the average size. Heart defects are also present in some Axenfeld-Rieger patients.<\/p>\n\n\n\n

The development of your eye is negatively impacted by Axenfeld-Rieger syndrome. This could lead to corneal irregularities that causes farsightedness<\/a>. There are some cases of Axenfeld-Rieger syndrome that are hereditary, but the vast majority is actually sporadic. Studies have shown that sporadic cases tend to be more severe when presenting symptoms in comparison to Axenfeld-Rieger cases that resulted from heredity.<\/p>\n\n\n\n\n\n\n\n

2. Diabetes<\/h3>\n\n\n\n

Diabetes <\/a>is a metabolic condition so you might be surprised to find it on this list. That being said, there\u2019s actually a good reason for its presence. You see, a rapid change in your blood glucose levels could lead to hyperopia. Patients who suffer from diabetes are unable to naturally regulate their blood glucose levels \u2014 often relying on artificial regulators such as insulin shots. The rapid fluctuation of glucose levels in patients with diabetes can cause farsightedness.<\/p>\n\n\n\n

That being said, this can often be avoided by simply adhering to the treatment plan for your diabetes. Beyond taking insulin shots as directed by your doctor, eating a balanced diet and getting enough exercise can also help stabilize blood glucose levels. Beyond farsightedness, other symptoms that may arise due to diabetes include fatigue, frequent urination, and weight loss. Cuts also heal slowly increasing the risk of infection. Be sure to report all symptoms to your doctor during visits.<\/p>\n\n\n\n\n\n\n\n

3. Cataracts<\/h3>\n\n\n\n

Studies have shown that almost half of all Americans will either have a cataract-removal surgery or cataracts <\/a>present in their eyes by the time they hit the age of 80. With the high frequency of cataracts, doctors have been looking into the various complications they can cause. Farsightedness is one of them. Your cornea is the part of the eye responsible for focusing incoming light and sending it to the retina.<\/p>\n\n\n\n

If the cornea is obstructed by the dense and cloudy cataract then it will send blurred light instead of focused light. This is the mechanism in which farsightedness occurs in patients with cataracts. That being said, the farsightedness typically goes away soon after the cataract is removed. As of now, the preferred method for treating cataracts is surgical excision, but doctors have spent the past few years looking for other viable treatment options that pose less risk.<\/p>\n\n\n\n\n\n\n\n

4. Chemical eye burns<\/h3>\n\n\n\n

When you hear the term chemical eye burns you often picture a dramatic event in which someone’s eyes are coated in acid after a barrel ruptures. Despite what the movies might suggest, chemical burns aren\u2019t normally this \u201cexciting\u201d to watch. Most chemical burns to the eyes are minor and will only lead to temporary discomfort. That being said, you should treat each chemical burn<\/a> with due diligence. Some burns could lead to vision loss and other permanent damage.<\/p>\n\n\n\n

That being the case, you should visit a doctor if your eyes have been exposed to any form of chemical. This is especially true if you\u2019re experiencing symptoms such as farsightedness, general blurry vision, or pain in your eyes. Both acids and alkalis can cause damage to your eyes, though alkalis are generally more potent. Sodium hydroxide and hydrochloric acid are some of the strongest bases and acids respectively. Other chemicals can also lead to chemical eye burns. Farsightedness can be caused by any eye damage, regardless of which chemical is to blame.<\/p>\n\n\n\n\n\n\n\n

5. Short eyeball<\/h3>\n\n\n\n

Those who have eyeballs that are shorter than normal will experience farsightedness. During the early days of ophthalmology, no one knew why this was the case. Fortunately, modern medicine has come with answers to the long-asked question. The cornea is the part of your eye responsible for focusing light then sending it to the retina.<\/p>\n\n\n\n

When your eye is too short, there is a smaller distance between your cornea and retina <\/a>providing less time to focus the light. Any light coming from further away has more time to focus which is why it\u2019s still relatively clear. Objects that are very close, however, need to be focused by your cornea, which simply doesn\u2019t have enough time nor distance to do so due to the lack of distance between itself and the retina. This is why shorter eyeballs lead to farsightedness.<\/p>\n\n\n\n\n\n\n\n

6. Cornea plana<\/h3>\n\n\n\n

\u201cCornea plana<\/a>\u201d is the medical term used to describe a flat cornea and is, once again, another prime example of doctors overcomplicating their descriptions. You might wonder \u201cbut wasn\u2019t the cornea always flat?\u201d While that\u2019s how it may appear to the naked eye, it is actually dome-shaped. We just can\u2019t see the curvature of the cornea both due to its thin nature and also because it\u2019s literally on our eyes.<\/p>\n\n\n\n

That would be like trying to taste our stomach. \u201cCornea plana\u201d is generally inherited from parents or grandparents. As of yet, there is no proven way to treat the issue, but various options are currently in development. When the cornea is flat, it isn\u2019t as effective at focusing incoming light and thus will lead to farsightedness. Cornea transplants are one treatment option, though they do come with their own set of risks.<\/p>\n\n\n\n\n\n\n\n

7. Sclerocornea<\/h3>\n\n\n\n

Sclerocornea <\/a>is a condition in which two parts of your eye \u2014 the cornea and the sclera \u2014 blend together. This makes the cornea more opaque, blurring any light that comes in. Sclerocornea impairs the cornea\u2019s ability to focus light, but any light that comes from a farther distance will already be more focused and thus perceived as clearer. This is why patients who suffer from sclerocornea also have farsightedness.<\/p>\n\n\n\n

Sclecornea is a congenital condition meaning that it was present since birth. It is inherited from parents and grandparents. Fortunately, corneal transplants are very effective at resolving the issue. Once the cornea transplant has been completed, the farsightedness \u2014 along with any other ocular symptoms that the condition may have caused \u2014 will dissipate. Glaucoma, bleeding, and infections are some of the side effects that may result from these corneal transplants.<\/p>\n\n\n\n\n\n\n\n

8. Limbal dermoids<\/h3>\n\n\n\n

Limbal dermoids are benign tumors that are made up of tissue that you wouldn\u2019t normally expect to see in the eye. They are congenital meaning present since birth. The iris and the cornea are the two parts of the eye most commonly affected by these dermoids. A wide variety of tissue could be found in these limbal dermoids. Fat, skin, and muscle <\/a>are some of the most common types of tissue that you might find in these limbal dermoids.<\/p>\n\n\n\n

That being said, there are some cases where teeth or even bone may be present. These cases are far rarer, however. The limbal dermoid, if present on the cornea, can partially obstruct the light coming in and make the image more blurry. This effect is amplified for any light that comes from a short distance as it is less focus \u2014 which is why those with corneal limbal dermoids tend to also have a farsighted vision.<\/p>\n\n\n\n\n\n\n
