Hyperopia - What to do about it
What is Hyperopia?
Hyperopia or farsightedness is a common condition of the eye wherein you can see objects at a distance clearly but may find nearby objects blurry. In short, your eyes focus on distant objects better than on nearby ones. Sometimes hyperopia is also referred to as hypermetropia.
This problem takes place when the rays of light entering your eye, focus behind the retina, instead of on it. A hyperopic patient’s eyeball is shorter than average. Many children are born hyperopic, but outgrow the condition as the eyeball grows with other body parts.
Causes of Hyperopia
Hyperopia stems from a refractive error. A refractive error takes place when your cornea or lens isn’t evenly or smoothly curved, leading to improper refraction of light rays.
Let’s take a better look at the science behind this.
Your eye has two parts that focus on images.
- The cornea is the clear, dome-shaped tissue that forms the front of the eye. It acts as a window and is what allows light to enter the eye. It helps your eye to process the focusing of light rays, that in turn, allows you to see words and images clearly.
- The lens is a transparent and flexible tissue, which is found right behind the iris and pupil, that helps focus light and images on your retina.
In an eye without visual problems, these eye parts have perfectly smooth curvatures, like a marble’s surface. A cornea and lens with such curvatures refract (or bend) all incoming light to create a sharply focused image directly at the back of the eye on the retina.
In case your cornea or lens isn’t curved evenly, light rays aren’t correctly refracted, leading to a refractive error. Hyperopia or farsightedness is when your eyeball is shorter than normal, or when your cornea is curved too little. The opposite effect is myopia or nearsightedness.
Another refractive error would be astigmatism, which occurs when your cornea or lens is curved more steeply in one direction than it is to another. This when uncorrected, blurs vision.
The initial signs of farsightedness are:
- Nearby objects may appear blurry.
- Difficulty in concentrating or focusing on nearby objects- leading to the need to squint.
- You may experience eyestrain or feel tired when working on something in close range. You may also feel burning eyes and aching around the eyes.
When you should see a Doctor
If the extent of farsightedness is such that you’re unable to perform tasks as well as you wish, or if the quality of vision deters you from enjoying daily activities, it’s time to visit the optometrist. They’re qualified to determine your degree of farsightedness and provide you with the best options to correct your vision.
Since it may not be evident that you’re having vision issues, it’s recommended to go for regular eye checkups as per the following intervals:
If you’re at risk of eye conditions such as glaucoma, it’s recommended to get a dilated eye exam every 1-2 years, starting from the age of 40.
However, if you don’t wear eyeglasses or contact lenses, neither do you have symptoms of eye trouble and are at low risk of developing diseases such as glaucoma, the following intervals are a good guide as to how often you should get an eye check-up.
- An initial exam at the age of 40
- Between 40-54, every 2-4 years
- Between 55-64, every 1-3 years
- 65 onwards, every 1-2 years
If you have an eye prescription or a health condition that affects the eyes like diabetes, it’s better to have your eyes examined on a regular basis. Ask your optometrist how often you need to schedule your appointments. However, it goes without saying that you should schedule an appointment with your optometrist as soon as possible if you notice problems with your vision- this is even if you have recently had an eye exam. Your optometrist will help you determine whether you would just need a prescription change or whether there could be another underlying problem linked with the rest of your body.
Children should ideally be screened for eye diseases or vision correction at the following intervals by a pediatrician, optometrist, or trained screener::
- At 6 months
- At 3 years
- Before 1st grade and every 2 years during school years.
Adults usually don’t suffer from hyperopia associated complications. Some children may face problems such as lazy eye (amblyopia), crossed eyes (strabismus), development delays, and learning problems.
- Hyperopia can be corrected with eyeglasses or contact lenses that change the way the light rays bend in the eyes.
- Prescriptions with plus numbers infer those for farsightedness.
- Typically, hyperopic prescription eyeglasses only need to be worn when working on close-up objects such as reading a book or working on the computer.
- High-index aspheric lenses help with this correction, especially for strong prescriptions, without the “bug-eye” appearance that such eyeglasses usually come with. For the best comfort and clear vision, we recommend, opting for our high-performance Arise HD Clarity lenses. For children, we recommend polycarbonate lenses as they’re highly durable, lightweight, and impact resistant. In addition, for enhanced outdoors protection, we recommend photochromic lenses, which automatically darken with UV light
- Refractive surgeries such as Lasik help in correcting hyperopia, thereby reducing or eliminating the need to wear prescription eyeglasses.
Your hyperopia prescription for both glasses and contact lenses will be a positive number under ‘sphere’. The more positive the number is, it means the stronger your prescription is. For more information on how to read your prescription, see our handy guide here.
Difference Between Hyperopia and Presbyopia
Hyperopia is the condition where distant objects can be clearly seen but close-up objects seem blurry. This condition can occur at any age, however, individuals are often born with it.
Presbyopia is the condition where nearby objects appear blurry even with glasses. This usually starts around the age of 40 and progresses through the age of 60. This is when individuals resort to reading glasses or eventually upgrade to progressive or multifocal lenses.
Difference Between Hyperopia and Myopia
Myopia is when light enters through the cornea, gets refracted to a position in the eye before it reaches the retina, because of the shape of the eyeball. This results in the person being shortsighted.
Hyperopia, on the other hand, is when the light is refracted to a point beyond the retina, resulting in distant objects to be clear, but making activities such as reading and sewing difficult as nearby objects are blurry or unfocused.
