Light therapy is becoming increasingly popular as a treatment for seasonal affective disorder (SAD). It involves exposing yourself to specific wavelengths of light throughout the day. This helps regulate your body clock so that you feel happier and healthier during the dark months. Blue light therapy works by stimulating certain parts of the brain that produce serotonin, a neurotransmitter associated with happiness.
Blue light therapy uses special lights that emit short wavelength light. Some of the benefits include improved sleep quality, increased energy levels, reduced stress and depression symptoms, and enhanced mood. If you suffer from SAD, then blue light therapy could be beneficial for you. Read our buyers guide to learn more about blue light therapy and how it can help you live a happy and productive life.

Blue lights are commonly found in homes, offices, restaurants, retail shops, and hospitals. They're used to simulate daylight during nighttime hours. Typically, blue lights are placed above eye level so that they illuminate only the eyes. But, sometimes it's necessary to turn them on full blast to see where you're going.
The human body has circadian rhythms which regulate our sleep cycles. During daytime hours, we naturally produce melatonin which makes us sleepy. At night, however, our bodies start producing serotonin which stimulates us to stay awake. If you've ever been woken up by bright lights shining into your eyes, you know how disruptive this can be. That's why blue lights are useful for testing whether someone needs to wake up early or go to bed late.
Yes, exposure to too much blue light can cause health problems. Macular degeneration causes vision loss and blindness. Other studies show that excessive exposure to blue light can increase the risk of cancer.
It depends on the type of light bulbs being used. Incandescent bulbs contain mercury which poses a serious threat to humans. Fortunately, newer LED bulbs are safe to use. However, they emit a slightly warmer color temperature than incandescents. Consequently, they might disturb your sleeping patterns.
Some people prefer brighter lighting while others prefer softer lighting. Conversely, if you have insomnia, you might enjoy brighter lighting.
In general, replacing old bulbs with new ones isn't necessary. However, if you notice that certain areas of your house are darker than others, you might want to replace the bulbs. Otherwise, you run the risk of burning out your entire fixture.
Blue light tests measure the amount of visible light emitted by devices. If you own a smartphone, tablet, or laptop, it's important to know whether its screen emits too much blue light. Too much exposure to blue light has been linked to eye strain, headaches, sleep problems, depression, and cancer.
There are several ways to determine whether your electronic device produces too much blue light. One option is to purchase a blue light meter. Although meters are expensive, they're considered the gold standard among professionals. Meters are accurate and reliable. But, they're only useful if you already own a monitor. Otherwise, you'd need to purchase another monitor to compare it to.
Another way to check the level of blue light produced by your electronic device is to simply hold it next to your eyes. If it appears brighter than normal, it probably contains too much blue light.
Yes! While there isn't anything you can do to eliminate blue light entirely, you can reduce its effects. First, turn off automatic brightness settings whenever possible. Second, choose screens with lower levels of blue light emission. Third, wear sunglasses during peak hours of daylight. Fourth, limit your usage of electronic devices before bedtime. Lastly, invest in a pair of blue blocker glasses.
No. All you need is a pair of blue blockers. These glasses filter out harmful blue light so you can enjoy the benefits of technology without suffering negative side effects.
Blue lights are essential tools for anyone working in a dark environment. If you're planning on purchasing a blue light test, it's important to know which features matter most to you. Here are some tips to help you choose the right model for your needs.
The size of the blue light test you purchase depends on where you plan on using it. Smaller tests are ideal for testing smaller areas such as bathrooms or closets. Larger units are useful for larger rooms such as bedrooms or living spaces.
Power consumption is another factor to consider when choosing a blue light test. Low power consumption is desirable because it saves money and reduces environmental impact. High power consumption requires additional batteries or electricity.
Some blue light testers only measure one wavelength of light. Others can detect multiple wavelengths simultaneously. Depending on your lighting situation, you might need both single and multi-wavelength devices.
There are two main categories of lighting: incandescent bulbs and fluorescent tubes. Incandescent bulbs produce white light by heating tungsten filaments inside the bulb. Fluorescent lamps create visible light by passing electrons through mercury vapor. UV rays cause skin cancer and eye problems.
Many manufacturers post information about their products online. You can learn about the product specifications, reviews, ratings, and customer feedback. Check out the manufacturer's website before making a purchase.
Blue light is emitted by electronic devices such as computers, smartphones, tablets, televisions, etc. If you've ever looked into purchasing a pair of sunglasses, you probably noticed that they block certain wavelengths of visible light. Similarly, blue light filters are designed to filter out specific wavelengths of blue light.
Blocking blue light has been shown to improve sleep quality and reduce eye strain. Research suggests that blocking blue light during nighttime hours improves melatonin levels which promotes restful sleep. Additionally, it's believed that blocking blue light reduces eyestrain caused by staring at screens too close to our eyes.
Yes! While blue light exposure does cause health problems, it doesn't pose serious risks.
While there isn't a single type of filter that blocks more blue light than another, polarized lenses are considered the gold standard among consumers. Polarized lenses are created by coating glass with tiny microscopic particles called polarizers. Polarizing filters are commonly found on sunglasses and prescription glasses.
Eye exams are important to ensure proper vision. Unfortunately, regular eye exams are expensive. Fortunately, you can purchase inexpensive blue light blockers at drugstores and optometrists' offices.
A blue light test measures how much blue light your eyes absorb. Blue light has been linked to sleep problems, depression, and even cancer.
To take a blue light test, simply look into a box filled with blue lights. If you have dark brown or hazel eyes, then you will likely have more blue light than someone with lighter eyes like green or gray.
No, your prescription doesn't change the amount of blue light that enters your eyes. Your prescription influences the strength of the light entering your eyes, but this isn't related to the amount of blue light that enters your eyes.
Taking a blue light test won't hurt. There's no pain involved. Simply put your head inside the box and look at the blue lights.
You don't need to take a blue light test every day. Every once in awhile is enough. Try taking a test after waking up, right before going to bed, and again first thing in the morning. Also try taking a test during the middle of the day.
Blue light tests are available online. They're also sold in drugstores and optical stores. Prices vary depending on where you buy them.
If you're worried about having a needle stuck in your arm, then you can use something else. A cotton swab is another option. Simply dip the end of the swab in alcohol and stick it under your skin. Then wipe off the excess alcohol.
Yes, you can take a blue light test without being tested. Simply go to a store that sells blue light filters and ask the salesperson to give you a free sample. You'll know whether or not you need to purchase a full set of blue light filters based on the result of your test.
Cataracts aren't always bad. Sometimes they make things easier to see. But sometimes they make things harder to see. That's why it's important to talk to your doctor about what kind of treatment would be best for you.
Glaucoma is a disease that damages the optic nerve. Glaucoma causes blurred vision and eventually blindness. People with glaucoma can lose their sight completely. Fortunately, most people with glaucoma never develop complete loss of vision. Instead, they experience milder symptoms like blurry vision or seeing halos around objects.
Macular degeneration is a type of age-related eye disease. Macular degeneration affects the central area of the retina, which is responsible for sharp, clear vision. As the disease progresses, patients begin losing their ability to read, drive, recognize faces, and perform simple tasks. Patients with advanced stages of macular degeneration may require surgery or injections to restore function.
Dry eye syndrome occurs when tears evaporate too quickly, leaving behind a thin film of mucus on the surface of the eye. Dry eye syndrome makes it hard to focus, and it can leave you feeling tired, irritated, and uncomfortable. Many people with dry eye syndrome notice that their vision gets worse when they wake up in the morning.
