If you or a loved one has been diagnosed with dry Age-Related Macular Degeneration (AMD), you know how frustrating it can be to hear that options for protecting your sight have historically been limited. Beyond lifestyle changes and specific eye vitamins, treatments for the early to intermediate stages of dry AMD were few and far between.
However, recent advancements in eye care technology have introduced a promising new option: light therapy, also known in the medical world as photobiomodulation.

To help you understand this innovative technology, we’ve answered some of the most common questions patients ask about light therapy for dry AMD.

What is light therapy for dry AMD?

Light therapy (photobiomodulation) is a gentle, non-invasive treatment that uses specific wavelengths of red and near-infrared light to support the cells in your retina.
Think of the retinal cells at the back of your eye as having tiny internal batteries called mitochondria. As we age—and particularly with dry AMD—these cellular batteries can lose energy, leading to cellular dysfunction and vision decline over time. The red and near-infrared light delivered during photobiomodulation helps stimulate these mitochondria, boosting energy production and supporting cell health.

How does light therapy help protect vision?

In clinical trials evaluating light delivery systems (such as the FDA-authorized Valeda® system), light therapy showed several key benefits for dry AMD patients:

  • Slowed Disease Progression: It slowed the movement toward severe vision loss and advanced stages like geographic atrophy.
  • Reduced Drusen: It helped reduce the buildup of drusen—the tiny metabolic waste deposits that accumulate in the retina during dry AMD.
  • Improved Visual Acuity: Some patients in clinical studies saw measurable improvements on eye charts, gaining two or more lines of vision clarity.

    • Am I a good candidate for light therapy?

    Light therapy is primarily aimed at individuals with early to intermediate dry AMD who still retain functional vision (typically between 20/30 and 20/100).

  • Wet AMD: Light therapy is not authorized for wet AMD, which requires specialized injections to manage leaking blood vessels.
  • Advanced Dry AMD (Geographic Atrophy): While it cannot reverse vision loss in tissue that has already been destroyed, it may offer support if central vision tissue is still intact.

    • A thorough comprehensive eye exam and retinal evaluation at our clinic are necessary to determine if photobiomodulation is appropriate for your specific stage of AMD.

    What is a treatment session like?

    Treatment is fast, simple, and comfortable:

  • No Dilating Drops Needed: You won’t need to have your eyes dilated before the procedure.
  • Quick Duration: Each session takes roughly 4 minutes per eye, with the whole visit usually lasting under 10 minutes.
  • Painless Experience: You simply sit comfortably in front of the device and look into the light source (alternating between eyes open and closed as directed).

    • In clinical settings, a full course of light therapy is typically administered periodically (e.g., every four months) to maintain visual outcomes.

    Can I buy a red light device online to use at home?

    We strongly advise against buying over-the-counter red light devices or glasses online for eye conditions.
    Clinical light therapy devices are calibrated to deliver exact, safe wavelengths and intensity levels of light directly to the retina. Unverified or unmonitored home devices lack safety testing for ocular use and could potentially cause damage to delicate eye tissue if misused or overused. Always seek treatment administered directly by trained eye care professionals.

    Is light therapy covered by insurance?

    Because medical-grade light therapy is a relatively recent technological authorization for dry AMD, Medicare and most private health insurance plans do not currently cover it. As a result, treatment is usually an out-of-pocket investment. Our clinic team is happy to discuss payment options, scheduling, and what to expect during your consultation.
