Night mode reduces blue light emissions by 20–50% depending on the device and settings. While blue light is still present in smaller amounts which helps, blue light is still present. It can still disrupt sleep by suppressing melatonin production. Minimizing exposure in the evening may improve sleep quality and reduce eye strain, however, a more effective approach is to eliminate screen time entirely for a few hours before bed. This allows your body to detox from all blue light, not just a diminished amount, promoting better rest and eye comfort.
Are Sunglasses or Transition Lenses Necessary Outdoors When Wearing Eyeglasses?
I question whether sunglasses are truly necessary or simply a modern invention driven by profit. A century ago people didn’t commonly wear sunglasses. Instead, they used hats with visors to shield their eyes from bright sunlight, otherwise allowing natural light to reach them.

Sunglasses can be harmful because they block ultraviolet light, which is essential for vitamin D production in the skin. Vitamin D supports overall health, including eye health, by bolstering the immune system and potentially reducing the risk of conditions like age-related macular degeneration. By wearing sunglasses you limit UVB exposure, which may lead to vitamin D deficiency, indirectly harming your eyes and general well-being.
Do Anti-Glare Coatings Protect Our Eyes from Computer Screens?
Anti-glare (anti-reflective) coatings are marketed as reducing eye strain, but scientific evidence is limited on whether they significantly prevent or alleviate digital eye strain (computer vision syndrome) or long-term eye damage. They’re also promoted for improving night driving by reducing glare from headlights or streetlights. I happened upon a 2019 review in Ophthalmic & Physiological Optics which found no improvement in visual performance or safety for night driving with anti-reflective coatings. In some cases these coatings distorted light in low-contrast conditions worsening vision for certain users. Given the cost, I’d approach anti-glare lenses cautiously. Try them if your budget allows, but evaluate their effectiveness for yourself.
Can You Restore Eyesight and Dental Health Naturally?
The potential for natural restoration depends on the condition. For functional issues (like eye strain or mild focusing issues), the eyes can be likened to muscles that may improve with targeted exercises. Our environment contributes to many modern eye issues. We constantly stare at computers 18 inches away, phones 12 inches away, and TV screens, all while exposed to harsh LED lighting. To counter this, spend time outdoors, practice focusing on distant objects, and get natural sunlight. These habits can significantly benefit eye health, though they’re unlikely to reverse structural conditions like myopia.
Here is to seeing better! Have a great day folks!

Blue light is indeed harmful, but I think the amount of exposure from digital devices is miniscule compared to the amount we are subjected to by artificial lighting. And car headlights are probably the main culprit.
ReplyDeleteAs for myopia, I've seen some sources claim that exercises, such as repeatedly changing focus from a very distant object to a ver close one, may mitigate such conditions.
The three components of teeth are dentin (making up the bulk), cementum (covering the lower part) and enamel. Of these three, dentin and cementum can regenerate, eg. in response to an acid attack. However, enamel can not be regenerated in the same manner. It can only be remineralized by saliva, if weakened in response to an acid attack. Some people claim that glycerine found in some toothpastes will prevent saliva from remineralize enamel. There has been research to find a way to repair tooth enamel by mimicking the body's natural way of producing enamel. Here is a link to one such study: https://pubs.acs.org/doi/10.1021/acsbiomaterials.2c01039
It was conducted at Genetically Engineered Materials Sciences & Engineering Center at Washington University and led by prof. Mehmet Sarikaya. The aim was to develop a lozenge that would repair enamel.
Even though humans cannot naturally regrow entire teeth, there are some mammals, such as elephants, that will grow six sets of molars throughout their lifetime.
I think its all bad... and intentional...
