The clinical suspicion for hyperopia or farsightedness is usually clinched when patients present with following signs and symptoms:

  • Frequency in squinting during focus to a nearby object.
  • Complains of a blurry vision when object in focus are brought near the eyes.
  • Recurrent eye strain characterized with the frequent burning sensation and aching of the eyes.
  • Periodic headaches and eye discomfort during prolonged intervals of reading and using a computer.
  • Difficulty in concentrating and maintaining a clear focus on nearby objects.
  • Occasional bouts of double vision.
  • Frequency in periods of unexplained fatigue.
Broad Thumb
  • A family is reported with conductive hearing loss, hyperopia, broad thumbs and broad first toes.[ncbi.nlm.nih.gov]
  • No gender influence was found for hyperopia, strabismus or malocclusion.[ncbi.nlm.nih.gov]
  • The patient and his family had many congenital anomalies including hereditary brachydactyly, syndactyly, and hyperopia. The association of these anomalies seems not to have been previously reported in the literature.[ncbi.nlm.nih.gov]
Blurred Vision
  • These findings were responsible for the blurred vision that was reversed by chalazion resolution or removal.[ncbi.nlm.nih.gov]
  • Intensive glucose reduction may cause transient hyperopia changes in newly diabetic patients and results in blurred vision.[ncbi.nlm.nih.gov]
  • A 47-year-old woman, who had undergone refractive surgery for radial keratotomy in both eyes 22 years before the present study, presented to our clinic with blurred vision.[ncbi.nlm.nih.gov]
  • Hyperopia develops in eyes that focus images behind the retina instead of on the retina, which can result in blurred vision. This occurs when the eyeball is too short, which prevents incoming light from focusing directly on the retina.[aea-ny.com]
  • This causes blurred vision. Astigmatism is due to an irregularly shaped cornea , toric crystalline lens or toricity of the retina.[mastereyeassociates.com]
Eye Pain
  • Reading in particular can cause asthenopic symptoms such as eye pain or headache , burning sensation in the eyes, blepharoconjunctivitis, blurred vision, and rapid fatigue. Esotropia can also occur, as was mentioned above.[alpfmedical.info]
  • See your doctor if you develop changes in vision or if you have eye pain, red eyes, or a discharge from your eyes.[healthline.com]
Vision Disorder
  • Definition A hyperopia is a vision disorder, not a disease. A hyperopic eye is too short eye, the image of a distant object is formed so behind the retina. Symptoms Symptoms of farsightedness can include: Blurred vision, especially at night.[provisu.ch]


Hyperopia is easily diagnosed with a simple eye examination. Other instrumentation like funduscopy (direct examination of the retina) or slit lamp examination may be used to demonstrate any defect in the eye’s anatomy.

Staphylococcus Aureus
  • Corneal smear culture showed a positive growth of Staphylococcus aureus. The patient was immediately treated with subconjunctival gentamicin and intensive topical ofloxacin 0.3% with systemic cephalosporin.[ncbi.nlm.nih.gov]


The conservative treatment of hyperopia includes the prescription of graded lenses (glasses) and the use of contact lenses. The early use of corrective glasses and contact lenses in the treatment of hyperopia in children reduces the temporal risk for advanced age myopia [6]. 

For corneal imperfections, refractive surgery may be applied to correct vision. These are the most common refractive surgical procedures done in hyperopia correction: Laser assisted in situ Keratomileusis or LASIK [6], Laser assisted subepithelial keratectomy or LASEK, Photorefractive Keratectomy or PRK [7], Conductive Keratoplasty or CK.


Congenital or acquired hyperopia may easily be addressed with proper prescription lenses or corrective ophthalmologic surgery. In some cases, mild hyperopia may resolve spontaneously. Mortality with hyperopia rarely occurs but are usually related to driving accidents or industrial accidents in heavy equipment due to an impaired visual acuity.


Hyperopia is commonly associated with the following complications:

  • Reduction in the quality of life: Daily chores and activities are adversely affected with a hyperopic visual impairment. Children and adults with farsightedness may experience learning problems in school [4].
  • Headache and eye strain: The unconscious desire to focus on the blurry objects may lead to eye strain and headache especially in cases of chronically uncorrected hyperopia.
  • Strabismus or squinting in children with farsightedness may often succumb to this complication which are easily addressed with a corrective prescription glasses [5].
  • Impaired safety: Hyperopia can adversely affect driving skills and reduce one’s capacity to safely operate industrial heavy equipment. This impairment heightens the risk for accidents.


In the normal eye, there are two distinct parts that focuses the image – the cornea and the lens. They both have a soft curvature that refracts (bends) the image and focuses it to the retina.

Any imperfections in natural curvature of the cornea and the lens disrupts the focus off the cornea. While the eyeball is too short, images sent through the normal cornea and lens are focused at the back of the retina giving a blurry object in our vision.


There are no definite data as to the exact number of hyperopic individuals are in the population. Ophthalmologic data in the US suggest that there are millions of people suffering from hyperopia.

Approximately half of those wearing glasses and contact lenses suffer from farsightedness. Studies have shown that hyperopia is the most common refractive error in both Asian and Non-Hispanic white children [1].

Presbyopia or the natural tendency of the eye to be hyperopic with increasing age may occur in the great majority of the population. Presbyopia is oftentimes confused with primary hyperopia in clinical practice because of it close similarities [2].

The basic pathophysiology of hyperopia or farsightedness is the refractive error that take place in the eye. With normal image and light refraction by the cornea and the lens, the image is practically brought exactly on the retina.

Patients with a pathologic thickening of the cornea will refract the light and image improperly bringing the image beyond the retinal surface. This hyper-refraction gives a blurring in the vision. Error of refraction in the lens also displaces the image and light away from the retina giving a similar symptomatology as the former. Nanophthalmos or the abnormal placement of lens near the retina will obscure focusing and cause hyperopia [3].

In cases where the eyeball is shorter in diameter than usual, normal refractive elements (cornea and lens) may still over shoot the image beyond the retina. The problem in the focus may easily be correctable when the image is brought farther from the eye to bring the image exactly on top of the retina. In far sightedness, patients makes an unconscious effort to focus on the blurry object. This extra effort may cause eye fatigue, tension, discomfort and occasional headaches which may be severe.


In general, congenital and acquired hyperopia may not be preventable. The following tips of prevention may however protect your eyes and your vision:

  • Regular eye check-up with an ophthalmologist.
  • Shield your eyes from the sun. The wearing of shades and sunglasses significantly protects your eyes from the ultraviolet light from the sun which can damage your eyes.
  • Control of chronic illnesses. Patients with long standing diabetes mellitus and hypertension may lead to complications that may impair vision if left untreated
  • Eye vigilance is important. Patient should pay particular attention to any acute visual disturbances like blurring of vision, flashing of light, black spots, perception of halos in the vision. These innocent signs may herald an impending serious eye disorder or a neurologic event.
  • Refrain from smoking. Nicotine can damage almost all kind of cells in the body including your eyes. Smoking pregnant mothers has been demonstrated to increase the incidence of hyperopia in the unborn child as depicted in a large cohort study [8].
  • Consume healthy foods: The regular consumption of fruits and vegetables with high vitamin content and antioxidants may prevent the emergence of macular degeneration that affects vision and the retina.
  • The use of proper prescription glasses is very important to ensure that the defect is corrected properly. 
  • Better lighting at home and in work can provide good lighting contrast for the eyes and keep them healthy.


Hyperopia or more commonly known as “farsightedness” is a clinical condition characterized by the difficulty in focusing in nearby object which gradually improves when the object in focus is brought to a nearer distance.

Clinically, hyperopia occurs when the eyeball’s diameter is shorter than normal, or the corneal curvature is defective enough to impair normal focusing. Farsightedness is believed to be hereditary in nature or may be influenced by environmental factors. A number of hyperopic individuals may actually be born with the condition. Hyperopia may easily be correctable with use of spectacle glasses or eye surgery.

Patient Information

Patients must understand that farsightedness or hyperopia is very common. Any changes in the quality of vision or any detraction on your everyday enjoyment must be brought promptly for medical or ophthalmologic evaluation.

Adults reaching the age of 40 must submit for a baseline eye examination and a regular eye check-up every two to four years before the age of 55. Frequency of visits may be adjusted yearly beyond the age of 60 years. However, those with prescription glasses and contact lenses must visit their doctors annually. Children and adolescents who are at risk should be regularly screened by their pediatricians [9].
