In recent years, light therapy has gained popularity among individuals who suffer from Seasonal Affective Disorder (SAD), depression, and sleeping problems. This form of treatment uses a light box to simulate natural sunlight, which can enhance mood, boost energy levels, and regulate sleep patterns.
However, many users might ask, “Are SAD lights bad for your eyes?” Whether you are new to light therapy or have been using a light box for years, understanding its impact on eye health is essential.
Understanding Light Therapy
First and foremost, it’s important to further understand what light therapy is and its benefits. Light therapy involves exposure to artificial light designed to mimic natural sunlight. It is believed that conditions such as Seasonal Affective Disorder are heavily influenced by light exposure when individuals who do not get enough sunlight experience symptoms of depression.
Light boxes emit broad-spectrum light, typically at an intensity of 10,000 lux, to facilitate seasonal light therapy. For SAD, light therapy alleviates the symptoms of sadness and lack of energy caused by a lack of sunlight exposure. On the other hand, light therapy helps regulate sleep patterns, ideal for individuals with sleeping disorders like insomnia.
A session of light therapy can typically last from 20 to 30 minutes a day, depending on the individual’s recommended duration. Some people even use their light box for 60 minutes. It’s highly recommended to do the sessions in the morning for maximum effectiveness. Setting a consistent routine of using the light box daily will yield positive results in the next few weeks.
Just like any other type of treatment, light therapy may cause side effects to certain individuals. Side effects may vary from person to person, so it’s important to delve into how light therapy impacts your eyes, body, and mind. Learning about these side effects can ensure the safe and effective treatment a light box can provide without any potential risks.
The Effects of Light Therapy on Eyes
Since every type of light is different, they can all have different effects on your body. Full spectrum lights have harmful UV rays that need to be properly diffused so that the ultraviolet rays don’t reach your eyes. If your eyes were exposed to UV rays in close proximity, they could get sunburnt, and it could cause serious damage, including the risk of blindness.
When choosing a light therapy box, it is very important to find a unit that uses broad-spectrum lights. Broad-spectrum lights do not contain ultraviolet rays, so they are perfectly safe to use every day. With these seasonal depression lamps, there are very few possible side effects—these include eye strain or a headache.
Eye Strain
A common side effect of seasonal light therapy is eye strain. Prolonged exposure to bright light can cause discomfort, leading to tired or strained eyes. You are more likely to experience this side effect if the light box is on maximum brightness or directly facing toward your eyes. This is also more likely to happen if the light box is used for extended periods.
Increased Sensitivity to Light (Photophobia)
A possible side effect that users may develop is temporary sensitivity to light during or after sessions. Constant exposure to a bright light may be glaring to some users, leading to discomfort when exposed to regular lighting outside the therapy.
Mild Headache
Another common side effect is getting a headache, often caused by eye strain. When the eyes are strained from trying to adjust to the bright light, it can trigger headaches. The headaches are usually temporary and may go away shortly after the session, but they are still bothersome to experience. Headaches can also result from prolonged squinting or discomfort.
Temporary Blurred Vision
In some cases, prolonged exposure may lead to blurry vision. This can also happen if the user stares directly into the light source, especially when it’s set at maximum brightness. Fortunately, the blurred vision only lasts for a short while after the session, but it may still be a frustrating side effect for some users.
Effects On Pre-Existing Eye Conditions
Those with conditions like cataracts, glaucoma, or macular degeneration may be extra sensitive to light therapy, as it may exacerbate discomfort or worsen symptoms. Caution must always be practiced when administering light therapy, especially if your eyes are sensitive due to pre-existing eye conditions.
Even if you experience one of these side effects, it probably won’t be for long. Once your body has adjusted to the extra light it is absorbing (about three sessions), any side effects from your therapy lamp will usually stop happening. With very few possible side effects, a broad-spectrum therapy light is the way to go.
Managing Light Therapy Effects on Eyes
With these side effects, it’s natural to wonder, “Is LED light therapy safe for the eyes?” The reassuring answer is yes, as long as it’s used properly. A light box is not harmful if used correctly. Here’s how to use a light box to mitigate and avoid potential side effects.
Start Slowly
When starting light therapy for the first time, it’s recommended to begin with shorter sessions and gradually increase the duration over time. You can start with 15 minutes daily for one week, then proceed with 20 minutes, followed by 30 minutes, and so forth. This will give your eyes time to adjust to the brightness of the light box without experiencing overwhelming strain.
Position the Light Box Properly
Always ensure that the light box is placed at the appropriate angle—above or slightly to the side of your eyes. Keep the light box at a safe distance, around 24-30 inches away, and avoid looking directly at the light source.
Engaging in a relaxing activity, such as reading or working, while positioning the light box in your peripheral vision is a good practice. This will reduce direct glare and cause eye discomfort.
Consult with an Eye Specialist
If you have existing eye problems or sensitivity, it’s always wise to consult with an optometrist or ophthalmologist to provide you with guidelines on how to take care of your eyes during light therapy.
They can advise you on the length of your sessions or the recommended brightness level. Seeking help from a professional can prevent further complications and ensure safe practices when using a light box.
Choose the Right Light Box
When selecting a SAD light therapy box, make sure to look for devices that are free of UV rays. Since UV light can be damaging to the eyes, it’s highly recommended to purchase a light box that uses broad spectrum lights, such as Alaskan Northern Lights. With a UV-free light box, you are able to protect yourself from developing eye conditions like cataracts or retinal damage.
When To See A Doctor
Although managing the side effects of a light box is easy, some individuals may need to seek medical advice if these effects don’t go away. If you experience persistent or severe eye discomfort, it’s crucial to seek professional advice.
At the same time, if you already have pre-existing conditions, such as cataracts or photosensitivity, you will need to be extra careful when using a light box to avoid the worsening of your condition.
Through medical advice, you will be able to address any severe side effects and make the necessary adjustments in the way you use light therapy advice. Furthermore, if you experience sudden or severe visual changes, stop using the device and consult an eye doctor.
