Answer – Yes!

Various scientific studies have clearly proved that exposure to blue light, particularly in the evenings, can suppress or reduce melatonin production, causing irregular sleeping patterns. Prolonged exposure to blue light doesn't only disrupt your sleep pattern but may cause eye strain and 'Digital" eye fatigue, leading to macular degeneration over time. 

Sleep ZM's blue light blocking glasses protect your eyes from harmful blue light, regulate your natural sleep patterns, and improve visual comfort and clarity during screen use.

Answer – It primarily depends on the type of lens and your goals. 

At Sleep ZM, we recommend using our blue light glasses anytime you're exposed to artificial blue light. In essence, wear blue light blocking glasses whenever you're exposed to digital devices or artificial light, especially in the evening or night. 

Irrespective of whether you're reading under artificial light, gaming, working on a computer, or scrolling on your phone – wear blue light blocking glasses to shield your eyes from avoidable eye strain and fatigue. 

Most importantly, wear them in the evenings 2-3 hours before bedtime to regulate your sleeping cycle. This is because exposure to blue light around evening time can suppress melatonin production, leading to you staying awake for longer and waking up feeling tired. 

In severe cases, it may even lead to insomnia, macular degeneration, and other eye-related issues.

Note – Don't abstain entirely from the sun or blue light during the day. It can disrupt your circadian rhythm and may lead to anxiety, depression, and mood swings.

Answer – When it comes to effectiveness, accuracy, affordability, and style – Sleep ZM has no competition in the market. Backed by years of research and designed to perfection – our exclusive collection of blue light blocking glasses helps reduce eye strain, improve sleep quality, and positively influence your overall health and well-being.

Answer – Yes & No!

Let us explain why -

You can wear Sleep ZM's blue light blocking glasses all day, every day, especially the ones that are clear or lightly-tinted. These clear or lightly-tinted blue light blocking glasses are designed to reduce eye strain, protect from blue light, and ensure no significant change in color perception. 

With that said, it's always good to remember that some exposure to blue light during the daytime, especially from the sun, is actually beneficial in boosting alertness. If you completely block out sun or blue light during the day for an extended period of time – it may result in you feeling depressed, anxious, or having mood disorders. 

So, while it's okay to wear blue light blocking glasses every day, don't block out blue light completely during the day.

Wearing red/orange and amber-tinted lenses is mostly preferred at night to help you doze off on time.
