To prevent dry eyes, eye fatigue, and disrupted sleep patterns, a person may wish to try to:avoid using electronic devices before bedtimeuse blue light screen protectors or filterssit with their eyes at a sensible distance from the computer screenadjust and reduce screen brightness on their devices What are blue light glasses A person wears blue light glasses to block out or filter blue light. Manufacturers claim that filtering the light protects the eye from potentially harmful effects. Some companies that manufacture blue light glasses also claim that their glasses can help:prevent headachesreduce eyestrainimprove sleep quality Do they work There is no conclusive scientific evidence to suggest that blue light glasses can protect a person’s eyes. A 2017 systematic review concludes that there is insufficient evidence to support the successful use of blue light glasses to improve visual performance or sleep quality. It also states that these glasses did not work toward alleviating eye fatigue or protecting macular health. Furthermore, the American Academy of Ophthalmology states there is not enough evidence to suggest that using blue-light-filtering glasses benefits people’s health. Is blue light harmful to the eyes Blue light has a wavelength that is roughly 400–500 nanometers (nm). Some researchers believe that blue light can damage the human eye, stating that peak light damage occurs at approximately 440 nm. According to a 2018 study that draws on evidence from animal studies, blue light can pass through the eye’s cornea and lens, where it may cause several health issues, including:dry eyecataractsage-related macular degenerationenhanced hormone production, which can directly impact sleep quality In contrast, another study suggests that acute exposure to blue light can be harmful to the retina, but long-term exposure to blue light emitted from digital screens does not create a biohazard. Yet another study notes that exposure to blue light before bedtime can disrupt their sleeping patterns, leading to poor sleep quality. Overall, more research will help determine whether long-term exposure to blue light from electronic devices harms a person’s eyes or vision. When to contact a doctor Generally, it is not necessary to contact an eye doctor before purchasing nonprescription lenses. However, if a person notices a change in their vision, such as finding it difficult to focus on objects that are near or far, or has symptoms such as itchy, swollen, or red eyes that do not go away with rest, they should make an appointment with an eye care professional as soon as possible. Frequently asked questions Below, we answer some commonly asked questions about blue-light-blocking glasses. Are blue-light-filtering glasses safe to wear all the time There is currently no evidence to suggest that using blue-light-blocking glasses poses any health risks. However, if a person experiences any headaches or eyestrain when using glasses, they should consider contacting an optometrist for an eye exam. Can blue-light-blocking glasses cause a headache There is currently no evidence to suggest that blue-light-blocking glasses cause headaches. However, eyestrain can cause headaches, as can changes in vision if a person does not wear the correct strength lenses. If people notice any changes in their vision, they should contact an eye doctor for an exam. Summary Blue light may be harmful to the eyes, but there is very little evidence to suggest that this includes the blue light from devices such as smartphones and laptops. Further research is necessary to determine whether the blue light that these devices emit may be harmful to the eyes over a long time. Some people wear blue light glasses to address any perceived issues that blue light may cause, and many lens options are available.
