Is nearsightedness influenced by genetics?

Struggling to read street signs or finding yourself inching closer to the TV might indicate you have nearsightedness (myopia). Many wonder if this blurring of distant objects is wired in our genes or influenced by other factors.

Dive into our latest blog post where we unravel the mysteries behind the causes of nearsightedness and explore the role of genetics.

What exactly is nearsightedness?

Myopia happens when the eyeball is elongated or the cornea is overly curved, disrupting the focus of light on the retina and blurring distant images. But why are some people affected and not others?

The genetic backdrop of nearsightedness

So is nearsightedness influenced by genetics? Research shows that genetics significantly contribute to the development of nearsightedness. If your parents wear glasses for myopia, chances are higher you might need them too. Several genes linked to myopia highlight its strong hereditary aspect.

Yet, it’s not all in the genes.¹Goldschmidt, E. and Jacobsen, N. (2014) Genetic and environmental effects on myopia development and progression, Eye (London, England). Environmental factors like extensive reading, computer use, and limited outdoor activities also play a critical role in developing nearsightedness. This blend of genetic traits and lifestyle factors paints a complex scenario.

Can you influence whether your children become nearsighted?

While you can’t alter your genetic makeup, knowing the risks allows you to adopt preventive measures. Regular eye check-ups, ensuring breaks during close-up tasks, and encouraging more outdoor time can significantly benefit children during their crucial developmental years.²Goldschmidt, E. and Jacobsen, N. (2014) Genetic and environmental effects on myopia development and progression, Eye (London, England).

Fortunately, numerous treatments are available to manage nearsightedness effectively and maintain optimal eye health. From corrective glasses to advanced options like laser eye surgery, eye care professionals can restore clear vision for nearly all individuals.

Advantages of laser eye surgery

Laser eye surgery offers a transformative solution for individuals seeking freedom from glasses and contact lenses. One of its primary advantages is the potential to achieve 20/20 vision or better³Saragoussi JJ, Djadi-Prat J, Lebuisson DA, et al. Quality of life after LASIK: part II. Quality of life and satisfaction of a population of patients treated with LASIK [in French]. J Fr Ophtalmol. 2011;34:294–302, which many patients experience following the procedure. The benefits extend beyond just sharp vision; laser surgery can significantly enhance your lifestyle, allowing you to engage more freely in sports, outdoor activities, and spontaneous travel without the encumbrance of corrective lenses.

Moreover, the surgery is known for its speed and efficiency, typically taking less than 30 minutes⁴Probst, The Optimization of LASIK, International Ophthalmology Clinics 48(1):p 9-16, Winter 2008.  https://journals.lww.com/internat-ophthalmology/citation/2008/04810/the_optimization_of_lasik.5.aspx for both eyes, with most people returning to their normal activities within a day or two. Long-term cost savings are also notable, as the need for new glasses, contact lenses, and related accessories is greatly reduced or eliminated.

Additionally, modern laser eye surgeries have a strong track record of safety and effectiveness, backed by decades of technological advancements and clinical research, making it a reliable choice for suitable candidates.
