When it comes to Blue-light protection, some blue-light blockers do more harm than good. In addition to preventing eye strain, some blue-light filters are ineffective and only block a tiny amount of blue light. These filters may be helpful for graphic designers who use colors on the computer, but they will do little to protect you from disrupted sleep. Ultimately, you will have to choose between these two options based on your needs and goals. These are the best blue light products to combat eye strain, so read on to learn more!
Some retailers sell inexpensive pairs of blue-light-blocking glasses. However, these glasses wear out quickly, can scratch, and may not offer the same level of protection. If you need prescription-grade blue-light-blocking glasses, you can opt for expensive ones, but they may also have inferior blocking capabilities. Also, manufacturers of these glasses lack standardization regarding their lens properties. Therefore, the only way to ensure your purchase is to compare the prices of different brands and styles.
Blue-light-blocking glasses have some benefits, but the main advantage is that they may improve your sleep. According to Vision Center, blue light is responsible for disturbing sleep patterns. Hence, exposure to too much blue light in the evening could disrupt this natural sleep-wake cycle. Using blue-light-blocking glasses may be the best option for adults, as they can block harmful light from entering the eye and improve sleep quality.
A clinical study has yet to prove that blue-light-blocking IOLs protect the retina from the damage caused by the blue rays of the sun. The study, which included data from 2010 to 2017, found that blue-light-blocking IOLs did not reduce the risk of subsequent neovascular AMD treatment. However, more research is needed to confirm the results of the study. For the time being, blue-light-blocking IOLs may benefit those with a history of cataracts, according to one of the study’s authors.
In the early 1990s, several companies started developing intraocular lenses that would block blue light. As the need for more effective vision treatment increased, ophthalmologists began replacing lenses with IOLs, and blue-light-blocking lenses were developed to reduce this type of light. Nevertheless, these lenses did not improve overall vision and were not recommended for patients with preexisting eye conditions. As these lenses have not been approved by the FDA yet, the research will continue.
Blue-light-blocking glasses for digital eye strain
The recent COVID-19 guidelines have boosted the sale of blue-light-blocking glasses. According to one study, more than a third of optometrists prescribed these glasses in the previous year. That high demand was partly due to the increased use of digital devices and patient requests. Optometrist Karen Walsh at Specsavers said the trend for blue-light-blocking glasses has surged in the past year. While the store is not actively marketing these glasses, she can apply them to customers who insist. So far, she has sold two pairs.
Saks carries an extensive line of luxury and designer blue-light-blocking glasses. These frames feature top brands like Kate Spade, Tom Ford, and Gucci. Besides blue-light-blocking lenses, these glasses also have adjustable nose pads, UV protection, and transitional features. Some pairs even allow you to change the lenses if needed. This eyewear can cost anywhere from $68 to $835.
Blue-light-blocking glasses for sleep
If you have trouble falling asleep, consider wearing blue-light-blocking glasses before you go to bed. Blue-light blocks have been shown to promote sleep and help you sleep faster. However, this does not mean that these glasses are the ultimate cure for sleep deprivation. Instead, you should use blue-light blocking glasses and other methods that promote sleep, such as reducing screen brightness before bed.
Using a tablet or laptop before bed can delay the release of your body’s sleep hormones. Wearing blue-light-blocking glasses can help you get a more restful night’s sleep and more energy during the day. Unfortunately, you may also find that using a tablet before bed delays the release of sleep hormones, leading to increased stress levels and poor sleep. However, if you cannot avoid using a screen before bed, you should invest in some blue-light-blocking glasses. Those glasses are effective for preventing eye strain and stress that can be associated with sitting at a desk all day.
