Myopia is the inability to see things clearly at a distance. Also called nearsightedness or shortsightedness, myopia is the most common refractive error among children and young adults.
Myopia occurs when the eye grows too long from front to back, causing light to come to a focus in front of the retina instead of directly on it. Other contributing factors include a cornea that is too curved for the length of the eyeball or a lens inside the eye that is too thick.
Distant objects and your driving vision will be blurry if you have myopia, but you still will be able to see nearby objects clearly. This is why the condition is also called "near-sightedness."
Blurry vision when looking at distant objects (e.g., front of a classroom, TV, street signs)
Difficulty seeing while driving a vehicle, especially at night
Holding books or devices very close while reading
Headaches caused by excessive eyestrain
Excessive blinking and/or rubbing eyes frequently from eyestrain
IMPORTANCE OF MANAGING MYOPIA
Excessive axial elongation associated with myopia can lead to structural changes in the of the eye leading to pathology.
Common associated conditions include: retinal detachment, cataracts, glaucoma, and myopic macular degeneration.
Lifestyle- more time outdoors
Multiple studies show that myopia progression decreases as outdoor time increases. The general consensus is that 60 to 90 minutes of outdoor time every day is beneficial for preventing myopia.
Low dose atropine drops is an option to slow progression up to 50%. Due to side effects such as: light sensitivity, reduced accommodation, gastrointestinal issues, and hallucinations we typically opt for more non-pharmalogic approaches.
Orthokeratology, or ortho-k, is the use of specially designed and fitted rigid gas permeable lenses to temporarily reshape the cornea to improve vision. Typically the lenses are worn at night to reshape the surface while sleeping. Statistically, these lenses slow progression by 45%.
Misight and NaturalVue are the first and only soft daily contact lenses that are used to slow progression of myopia on average by 38%. These specialty lenses have a defocused zone that works to halt progression while maintaining clear vision.
