Hyperopia is the official term that medical professionals such as eye doctors use to refer to farsightedness. This is characterized by a normal proficiency when it comes to viewing objects that are far away but a perceived blurriness if they get too close. It\u2019s worth noting that children who have moderate or mild hyperopia can generally offset the blurriness quite effectively through squinting due to the fact that their eyes are young and more adjustable.<\/p>\n\n\n\n

There are many symptoms that might come along due to hyperopia. Headaches after reading are common. Eye strain, blurry vision, and fatigue could also occur. In fact, the symptoms aren\u2019t restricted to reading. Other close-up tasks such as graphic design may similarly strain the eyes. During the early days of ophthalmology, some doctors didn\u2019t know what led to hyperopia. Fortunately, modern medicine has now identified eight common causes of hyperopia.<\/p>\n\n\n\n

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

The shape of your eyeball is essential to clear vision. If your eyeball is shorter than average then you may have a hard time processing images that are close properly. Things that are further away may appear more focused since the light has more time and space to focus before reaching your retina. People with shorter eyeballs don\u2019t receive light waves in the proper manner.<\/p>\n\n\n\n

Usually, light is focused by the cornea <\/a>onto the retina then processed by your brain. That\u2019s how most people see. Those with short eyeballs, however, will find that the light actually focused behind their cornea rather than on it which will make the image quite blurry. While short eyeballs can\u2019t focus images properly, it can still perceive pre-focused images which is why things that are far away can still look clear to those who suffer from hyperopia.<\/p>\n\n\n\n\n\n\n\n

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

Cornea plana<\/a> is another eye condition that could lead to hyperopia. You\u2019re like wondering what the term even means seeing as it sounds more like a foreign soap opera than a medical condition. Well, as we established earlier, the cornea is the part of your eye that focuses images onto the retina. In normal eyes, it\u2019s dome-shaped and thus is able to focus light properly. There are some cases, however, where the cornea is flat rather than dome-shaped. This is referred to as cornea plana.<\/p>\n\n\n\n

Cases of cornea plana can be treated, but the overall effectiveness of the treatment will depend on how early the issue was detected. There are some cases where the patient\u2019s flat cornea was detected too late and thus deemed untreatable or too risky to be worth treating. Flat corneas aren\u2019t all too common, but if you have one then it could lead to hyperopia, thus periodic eye checks are essential.<\/p>\n\n\n\n\n\n\n\n

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

Sclerocornea <\/a>is a condition that occurs when your cornea \u2014 the part of the eye that focused light onto your retina \u2014 blends with your sclera. It is classified as a congenital anomaly meaning that it was present ever since birth. There are some cases were sclerocornea occurs together with cornea plana. Patients who suffer from both eye conditions may have more severe hyperopia than those who only suffer from one. Most cases of sclerocornea are sporadic rather than inherited.<\/p>\n\n\n\n

That being said, there are some cases in which it may be passed down genetically through parents or even grandparents. Sporadic cases tend to be more severe than hereditary ones. The condition reduces the clarity of your cornea. As you can imagine, this will make it harder for your cornea to focus incoming light \u2014 leading to hyperopia. Corneal transplants can be performed to relieve symptoms.<\/p>\n\n\n\n\n\n\n\n

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

Limbal dermoids are benign tumors that could occur anywhere in, on, or around the eye. They are congenital \u2014 i.e. present since birth. The most common spot for limbal dermoids to form is in the cornea. These are referred to as corneal limbal dermoids. In limbal dermoids, various types of tissue that aren\u2019t normally found in the eye may be present. These include muscle, fat, cartilage<\/a>, skin, bone, and even teeth in some very rare cases.<\/p>\n\n\n\n

These limbal dermoids partially obstruct the cornea, impairing its ability to focus light onto your retina. It is very rare for a limbal dermoid to become cancerous. That being said, it can still cause issues due to its obstructive nature such as hyperopia. Surgical excision is the preferred treatment for limbal dermoids. Patients with limbal dermoids may suffer from dry eyes or double vision, but both will likely dissipate after treatment.<\/p>\n\n\n\n\n\n\n\n

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

Axenfeld-Rieger syndrome refers to a group of conditions that can impair the development of the eye. The iris and cornea are the most commonly affected parts of the eye in patients who suffer from Axenfeld-Rieger syndrome. Furthermore, half of all patients with Axenfeld-Rieger syndrome will develop glaucoma as well which is a condition that increases the pressure within your eyes \u2014 potentially causing various problems such as hyperopia <\/a>and even vision loss in some extreme cases.<\/p>\n\n\n\n

Other symptoms of Axenfeld-Rieger syndrome beyond hyperopia include abnormally small teeth as well as heart defects. The syndrome can be passed down hereditarily. That being said, the severity of the symptoms that the child will experience doesn\u2019t have to be identical to the parents. In some cases, it is less severe, while in other cases it\u2019s more severe, and the severity seems to be random in the way that it varies.<\/p>\n\n\n\n\n\n\n\n

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

While it may be surprising to see a metabolic disease here as one of the causes for an eye condition, it\u2019s actually a known fact that diabetes can lead to hyperopia. Sudden changes in glucose levels can lead to hyperopia. As you know, patients with diabetes are unable to regulate their glucose levels and thus it may rapidly fluctuate, leading to hyperopia. That being said, patients who receive regular treatment for their diabetes <\/a>often don\u2019t suffer from hyperopia or other eye-related complications.<\/p>\n\n\n\n

The standard treatment for diabetes is insulin. However, there are other methods that can help regulate blood sugar levels. The first of these is a healthy diet. Eating the right food will keep you healthy and maintain safe glucose levels. Regular exercise can also help your body regulate the amount of sugar in your blood. Sticking to your diabetic treatment is the best way to prevent diabetic hyperopia.<\/p>\n\n\n\n\n\n\n\n

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

A cataract <\/a>is a cloudy and dense region that forms on the lens of your eye. They occur when proteins in your eye start to clump together. This blurs the light before it can reach the retina and thus leads to hyperopia. More than half of all Americans will either have cataracts or cataract removal by the time they reach the age of 80.<\/p>\n\n\n\n

There are many symptoms that can be indicative of cataracts, and spotting them is the key to early treatment which can yield the best results. If you\u2019re seeing colors as faded or halos around lights then these may be symptoms of cataracts. Of course, hyperopia itself can also be a red flag that you might have a developing cataract. If you notice any of these symptoms then getting your eyes examined immediately is highly advised to nip the issue at the bud.<\/p>\n\n\n\n\n\n\n\n

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

If any part of your eye is exposed to chemicals then you may suffer from a chemical eye burn<\/a>. Most burns only cause minor discomfort and heal on their own. That being said, you shouldn\u2019t take them lightly. If you suffer a chemical eye burn then you should have your eye examined to see if there\u2019s a potential for permanent damage. In some severe cases, the cornea could be damaged leading to hyperopia.<\/p>\n\n\n\n

There are even some cases, albeit very rare, in which vision loss occurs. Lye and other alkali chemicals could be very damaging to your eyes. Pepper spray is a known irritant for your eye. That being said, it rarely leads to any vision loss or permanent eye damage. If you notice hyperopia after suffering from a chemical eye burn then you should visit an ophthalmologist immediately to treat the underlying issue.<\/p>\n\n\n\n\n\n\n
