It’s not unheard of for someone to worry when their vision becomes consistently blurry and they have trouble seeing what’s ahead of them. After all this may make work more difficult and worse, tasks like driving can be downright dangerous. This blurred vision may likely be caused by one or more of the four types of refractive errors and the most prudent step to take is to go to the eye doctor for an eye examination.

But in case you can’t go to your optometric physician right away, here’s some information on eye refraction that may prove useful to you:

TYPES of REFRACTIVE ERRORS

As mentioned earlier, there are 4 main kinds of eye refraction issues, namely:

  • Nearsightedness or myopia – nearsighted people can see nearby objects clearly but have trouble with objects in the distance. Myopia can be inherited and is mostly discovered during childhood. Really bad nearsightedness may increase your risk of retinal detachment so it is important to have your retina examined.
  • Farsightedness or hyperopia – Someone with hyperopia can see far away objects better than they can close objects. Like nearsightedness, this can be inherited and developed at a young age.
  • Presbyopia or age-related near vision loss – Usually discovered at age 40+ years old, this occurs when the eye’s lens becomes more inflexible, making it difficult to focus and read. Presbyopia can occur in addition to the other refractive errors.
  • Astigmatism – this happens when the cornea, lens or eyeball shape is asymmetrically curved where it is normally round. This issue makes images look distorted and vision may be blurry no matter how near or far the objects are.

Apart from seeing blurry images, people suffering from refractive errors may develop headaches due to frequent and prolonged squinting. Eye irritation, tiredness, and redness may also be experienced by people with eye refraction problems.

DIAGNOSIS and TREATMENT

Patients are usually tested for refractive errors during their regular eye examinations by using a vision chart and a variety of lenses which may help the patient see better.

Refractive problems are fixed with corrective eye glasses or contact lenses which are prescribed according to the results of the eye examination.

Aside from this, patients may also opt for CRT (Corneal Refractive Therapy) or LASIK surgery to treat myopia and astigmatism. CRT involves a molding lens that only specially trained eye doctors can fit. This therapy corrects your prescription overnight so that you have 20/20 vision during the day without the need for glasses or contacts, so long as you wear the molding lens overnight. LASIK is an outpatient procedure where the ophthalmologist uses a laser to reshape the cornea and correct the vision problem by helping the light that enters the eyes focus more accurately. It’s considered to be a permanent solution to wearing eyeglasses and contact lenses.

To-date, there is no permanent way to stem the development of presbyopia but people with this condition may see better with progressive lenses or reading glasses.

Refractive errors are nothing to be afraid of. While eyeglasses, contacts lenses, or the idea of undergoing LASIK surgery may require some getting used to, with proper care and patience, anyone can function as normally as they used to prior to the diagnosis of the refractive error. Just the same, we recommend that everyone have their eyes checked regularly by a reliable eye doctor to make sure there aren’t any underlying issues.
