Nearsightedness (Myopia) – What is it?
Nearsightedness, or myopia, the most common eye condition, has been increasing in occurrence among Americans at a rapid rate as of late. In fact, it’s now estimated around 40% of the United States population currently experiences nearsightedness complications and symptoms.
Although there isn’t any known reason for the increase in number of people suffering from myopia, many eye doctors and eye specialists believe the rising number of nearsighted individuals to be directly correlated with the increasing number of screens and computer-related work.
What Causes Nearsightedness?
Nearsightedness is the most common refractive eye condition. Nearsighted individuals are able to see objects up close, but have difficulty seeing objects that are further away. A nearsighted person might be able to read a book or computer screen close to their face, but will have a hard time reading street signs or seeing a clear, crisp skyline.
Myopia is caused when a person’s eye is too long, or has an overly curved cornea. Because the eye relies on refraction to process your vision, excessively curved and elongated eyes mean light isn’t focused properly, causing objects further away to appear blurry.
Although the scientific community has yet to clarify the exact cause of nearsightedness, genetics are thought to play a significant role in your likelihood of developing myopia. Due to the rapidly growing number of individuals being diagnosed with nearsightedness as of late, many eye doctors and experts believe that the average American’s increasing “screen-time” could also be partially responsible. If you spend a lot of time in front of a screen our eye doctors recommend giving your eyes a break for around 15 minutes every 3-4 hours. For those with unavoidable, excessive screen time, our eye clinic carries lenses to specifically combat computer vision syndrome.
During your comprehensive eye exam, your eye doctor will begin checking for nearsightedness with a visual acuity test. More often than not, this test will use the Snellen eye chart. If your visual acuity test indicates that you may be nearsighted, the eye doctor will use a retinoscope to look into your eyes and determine your eyes’ level of refractive error.
Nearsightedness Correction & Treatment
Prescription Glasses or Contacts
There’s many different options when it comes to treating nearsightedness, with prescription glasses and contact lenses being the most frequent. Here at In Vision Optical & Eye Care we have a large selection of eyeglass frames that we can customize to fit with your lens prescription.
Paragon CRT Contact Lenses
Paragon CRT contact lenses are a non-surgical alternative offered through our eye clinic. Corneal Reshaping Therapy Lenses work to reshape your eyes during the night, providing you with crystal-clear, lens-free vision during the day. CRT lenses can be a better alternative for children and young adults who are quite active at school, and in sports during the day.
Refractive Eye Surgery
Refractive Surgery, typically LASIK or PRK eye surgery, offer a permanent solution for nearsighted sufferers whose eyes have stopped growing. Refractive surgery is the only permanent, lens-free solution for those diagnosed with nearsightedness. The eye doctors at our eye clinic can help determine if you would be a good candidate for LASIK, recommend Rapid City’s best eye surgeons, and provide postoperative care along your journey to clear vision.
