Can blue light or AREDS2 affect AMD progression?

Question

Hello doctor,

I am 59 years old and was recently diagnosed with early dry age-related macular degeneration (AMD) during a routine eye examination. I also have a strong family history of the condition, as my mother experienced significant vision loss from AMD in her 70s.

The ophthalmologist recommended that I start using AREDS2 supplements, which I started not long ago. At the same time, I use the statin and blood thinner because of my heart condition, and I wonder whether it is okay to use them together with AREDS2.

In addition, I have seen on the internet that the excessive use of blue light emitting from smartphones, tablets, and computer screens may lead to worsening of AMD in the long run.

Is there good scientific evidence supporting this?
Would using night mode settings, blue-light-filtering glasses, or reducing screen exposure meaningfully help slow the progression?

I would appreciate guidance on how concerned I should be about these issues and what lifestyle measures are truly evidence-based for protecting vision with early AMD.

Please help.

Hello,

Welcome to icliniq.com

I have read your query and understand your concern.

AREDS2 supplements are commonly recommended for patients with age-related macular degeneration (AMD) who are at risk of progression, especially when there is a strong family history.

In most cases, AREDS2 (age-related eye disease study) can be safely taken along with medications such as statins and blood thinners used for heart disease.

However, it is always important to review the exact medications you are taking with your treating physician, as certain supplements, particularly vitamin E or other components, may require caution in some individuals, depending on dosage and overall medical history.

As for the blue light emission from digital screens, it is scientifically unclear whether or not the blue light emitted from these devices has any direct negative effect on the progression of AMD. Although the topic has been extensively covered by the public, there has been no research to confirm that it leads to retinal damage.

Using night mode settings or blue-light filtering glasses may still help reduce digital eye strain, glare, and sleep disruption in some people, but these measures have not been proven to prevent or slow AMD itself.

More important evidence-based lifestyle measures for AMD include:

Avoid smoking.
Maintaining good cardiovascular health.
Controlling blood pressure and cholesterol.
Eating a diet rich in leafy green vegetables and fish.
Regular ophthalmology follow-up and retinal monitoring.

Protect your eyes from excessive ultraviolet (UV) exposure outdoors with sunglasses is also reasonable and commonly recommended.

Since you have early dry AMD and a strong family history, regular follow-up with your ophthalmologist is especially important to monitor for any signs of progression.
