Using digital devices at night can suppress the release of melatonin, the hormone responsible for sleepiness. Excessive exposure to blue light from viewing screens at night can cause:

• Impact on our circadian rhythms
• Sleeping problems
• Waking up during the night
• Alert status reduced the following day

There is evidence that the The eye is susceptible to exposure to blue light and that, over time, cumulative exposure can increase the likelihood of vision problems. More research is needed to determine the long-term effects on the retina and their relationship to chronic vision problems.

Children may be more vulnerable because their eyes don't filter blue light as effectively as adults. Additionally, they tend to hold devices close to their eyes, which increases the intensity of high-energy visible blue light they receive. Twilight lamps and bulbs generate a slightly dimmer light that not only eliminates all blue light but also all green light. They are ideal for use in reading lamps, bedrooms and bathrooms, or anywhere you relax in the evening in the last few hours before bed, as they still provide enough light to read and see. They emit a deep orange to red glow. They are the ultimate in lamps to ensure the best possible sleep.
