A Curious Curve: Farsightedness and Your Precious Eyes

It’s pretty cool, right? You have vision like a hawk.

You can see perfectly far away. In fact, the farther, the better. The problem is you can’t read without getting a headache or without having to squint. It’s weird.

Things up close should be easy to read, shouldn’t they? Yes, they should. But, you may have a condition called “hyperopia.” Here’s what you need to know about it.

The Causes

No one really understands the root cause of hyperopia, but current research suggests that much of the cause of the condition is correlated with genetic factors. Hyperopia is a condition in which objects up close appear blurry while objects far away appear in focus.

This happens because the eyeball is smaller or flatter than it should be, causing light to enter the eye’s lens and bend – focusing behind the retina instead of on it. In order for objects to be in focus, the light must bend and then focus on the retina. To the extent that this does not happen is the extent to which you suffer from altered or distorted visual acuity.

Corrective Lenses

So, you know you have a problem. Now what? There are many options available, fortunately. You can opt for traditional corrective lenses or for surgery, and multiple options in between.

Corrective lenses are cheap and they will help you see better when working on the computer or when you are trying to read. Based on the degree of your refractive error, your age, and other factors, your doctor will help you determine which option is best.

If reading glasses will suffice, you will only have to shell out a few pounds for the lenses, and you’ll be sent on your way.

However, if you want to address the basic structural problem, you will need to opt for surgical intervention.

LASIK

LASIK treatment is a laser eye treatment that permanently changes the shape of your eye.

While many people are great candidates for this procedure, many are not. If your doctor determines that your vision is not stable, or you have refractive instability (your prescription keeps changing with each visit), then you will not be recommended for the procedure. You should contact a professional if you need more help deciding whether you’re a good candidate for this type of surgery.

Refractive surgery for hyperopia allows the doctor to cut a flap in your cornea. From there, a second laser is used to make surface adjustments to the shape and angle of your eye. For hyperopia, the doctor steepens the angle of the cornea.

This allows light to bend at a steeper angle, which then allows the light to focus onto the retina instead of behind it.

Once the second laser has made adjustments to your eye, the doctor replaces the flap and the procedure is over. You are send home to heal. It takes roughly 1 to 3 days for your vision to be restored. But, once it is, you will be able to see much more clearly. Over the next several weeks, you will have to come back to the doctor’s office for followup examinations.

Your vision should steadily improve until you have attained 20/20 vision, and you no longer suffer from hyperopia.
