Farsightedness or Hyperopia is considered a common vision issue affecting more than 25% of the American population. These patients have difficulty in focusing on things that are closer to them but can see distant objects without any issue. In fact, this vision problem is also known as Hypermetropia at times.
The Signs And Symptoms Of Hyperopia
Patients suffering from Hyperopia have eye strain and headaches most of the time. Their eyes may feel fatigued or squint when focusing on something at close range. If you experience such symptoms when wearing contact lenses or eyeglasses, you should get an eye examination and a new prescription for eyeglasses.
The Causes Of Hypermetropia
In fact, light rays that enter the eye of the patient suffering from this condition focus behind the retina instead of directly on the retina. The eyeball of a patient suffering from Hypermetropia is usually shorter than a normal individual. Although many kids are born with this condition, most of them outgrow the condition as their eyeball lengthens during growth. Most people confuse this condition with presbyopia – which causes the same problem but for different reasons.
Treatments For Hyperopia
Contact lenses and eyeglasses are used to change the way the light rays focus on the retina of the patient. If your eyeglass or contact lens prescription starts with plus digits (+2.50), you are suffering from Hyperopia. You might be asked to wear the glasses at all times or only when working on your computer, reading or doing something similar.
When selecting eyeglasses to correct this condition, you should look for aspheric high-index lenses, especially if you have a strong prescription. Such lenses are lighter and slimmer with an attractive profile. These lenses will also reduce the magnified “bug-eye” appearance that is most often caused by farsightedness. But aspheric high-index lenses will reflect more light compared to the plastic lenses on the market. The lenses should include an anti-reflective coating for the best appearance and comfort.
Aspheric lenses for kids should be made of polycarbonate material that is lightweight. It provides superior comfort and impact resistance at the same time. Also, photochromic lenses (darkens automatically when there is too much of sunlight) is ideal for kids who spend more time outdoors.
Hyperopia could be corrected using refractive surgery such as CK or LASIK. It may eliminate the need to wear contact lenses or eyeglasses. On the other hand, corneal implants could be considered a future treatment option for farsightedness.
