Understanding Myopia.

Myopia — commonly called nearsightedness — is a refractive error that causes distant objects to appear blurry while close-up vision remains clear. It occurs when the eyeball grows slightly too long or the cornea is too steeply curved, causing light to focus in front of the retina instead of directly on it. Myopia is extremely common, affecting over 40% of Americans.

Myopia develops from a combination of genetic and environmental factors. If one or both parents are myopic, the risk increases significantly. Environmental factors include prolonged near work (reading, screens), limited time spent outdoors during childhood, and extended close-focus activities. The prevalence of myopia has been increasing dramatically, particularly among younger populations.

Myopia typically progresses during childhood and adolescence, often stabilizing in the mid-to-late twenties. However, some adults do experience continued progression, particularly those with high myopia. Regular eye exams are important for monitoring any changes in your prescription and catching potential complications early.

High myopia is defined as a prescription greater than −6.00 diopters. It matters because the elongated eye shape associated with high myopia increases the risk of serious conditions including retinal detachment, glaucoma, early cataracts, and macular degeneration. Patients with high myopia should have comprehensive dilated eye exams regularly to monitor for these risks.

Myopia is diagnosed through a comprehensive eye exam that includes a refraction test, where your eye doctor determines the precise lens prescription needed to bring distant objects into focus. Additional tests may include corneal topography and an axial length measurement to assess the shape and length of the eye. At Soni Vision Institute, our evaluations also screen for any complications associated with myopia.

Yes, myopia commonly begins in school-age children and can progress rapidly during growth years. Warning signs include squinting to see the board at school, sitting too close to the TV, holding books very close, frequent headaches, and rubbing the eyes often. Children who develop myopia before age 8 are at the greatest risk for progressing to high myopia, so early detection through regular pediatric eye exams is important.

Genetics play a significant role in myopia. Children with two myopic parents have up to a 50% chance of developing nearsightedness, compared to roughly 10% when neither parent is affected. However, environmental factors — including time spent on near-focus tasks and limited outdoor activity — also contribute substantially. Even children without a family history can develop myopia.

For most people, myopia stabilizes in the early-to-mid twenties once the eye has finished growing. However, the timeline varies — some patients see stability by age 18, while others continue to experience small changes into their late twenties. A stable prescription for at least one to two years is typically required before surgical correction such as LASIK or EVO ICL can be considered.

LASIK is one of the most effective treatments for mild to moderate myopia, reshaping the cornea with an excimer laser to correct how light focuses on the retina. It can treat prescriptions up to approximately −11.00 diopters, depending on corneal thickness and anatomy. Most patients achieve 20/20 vision or better, with a rapid recovery — often noticing clearer vision within hours of the procedure.

PRK (photorefractive keratectomy) reshapes the corneal surface without creating a flap, making it an excellent alternative for patients with thinner corneas, active lifestyles involving contact sports, or those who are not ideal LASIK candidates. The visual outcome is equivalent to LASIK, though recovery takes slightly longer — typically one to two weeks for clear vision to emerge.

EVO ICL (implantable collamer lens) is a biocompatible lens placed inside the eye, behind the iris and in front of the natural lens. It is ideal for patients with high myopia (up to −20.00 diopters), thin corneas, or astigmatism that may disqualify them from laser procedures. The procedure is reversible, preserves corneal tissue, and offers excellent visual quality with built-in UV protection.

Yes. During cataract surgery, the clouded natural lens is replaced with an intraocular lens (IOL) that can be precisely calculated to correct your myopia. Patients with both cataracts and myopia can often achieve greatly reduced dependence on glasses after surgery. Advanced technology lens options — including toric, Extended Depth of Focus (EDOF), and multifocal IOLs — can address myopia along with astigmatism or presbyopia.

While myopia cannot be entirely prevented — especially when genetics are a factor — research shows that certain habits can slow its onset and progression in children. Spending at least two hours outdoors each day, taking regular breaks from close-focus tasks (the 20-20-20 rule), and maintaining good lighting while reading are all associated with reduced myopia risk. Early and regular eye exams allow for timely intervention if myopia does develop.

Extended screen time is associated with myopia progression, particularly in children and adolescents. The sustained close focus required by phones, tablets, and computers places continuous demand on the eye’s focusing system, which research links to faster axial eye growth. Limiting screen time, taking frequent breaks, and balancing near work with outdoor activity can help reduce the impact on developing eyes.

Most vision insurance plans consider refractive procedures like LASIK, PRK, and EVO ICL to be elective, so they are typically not covered. However, if myopia correction occurs as part of medically necessary cataract surgery, the procedure itself may be covered by medical insurance.
