Blue Light Glasses

Natural light has various coloured wavelengths. Blue light is a portion of the light wavelength that can be seen by human eyes. In our everyday life, we are constantly exposed to blue light emitted by the sun, artificial lights, televisions and digital devices such as smartphones, tablets and computer screens.

Generally speaking, natural light is composed of multiple colored wavelengths. Among these, blue light is a segment that is visible to the human eye. In our daily lives, we are continuously exposed to this type of light from various light sources. The sun is the primary source of blue light in the first place, but artificial light from light bulbs, televisions, and digital devices like smartphones, tablets, and computer screens also contribute significantly to our exposure.

Artificial blue light is quite pervasive in our modern environment, and it can interfere with our ability to fall asleep by disrupting our natural sleep cycles. This is where blue light glasses work their magic. These specially designed eyewear filter out the artificial blue light, helping to reduce eye strain and promote better sleep patterns.

Exposure to blue light, particularly from electronic devices, can have several negative effects on your health. According to information from Healthline, WebMD and Harvard Health, the most immediate side effect is digital eye strain. Symptoms of this condition include dry, irritated eyes, blurred vision, headaches, and fatigue. Over time, the strain on the eye muscles caused by blue light exposure can lead to more serious conditions such as retinal damage and phototoxicity. This is because blue light falls within the visible light spectrum, which is close to UV light on the electromagnetic spectrum. While the eye has protective mechanisms against harmful light, too much exposure to blue light can override these protections.

In addition to causing physical discomfort and potential damage to your eyes, blue light exposure can also have systemic effects on your overall health. Research cited by Harvard Health indicates that prolonged exposure to blue light, especially late at night, can disrupt your sleep patterns. This disruption can contribute to a host of health issues, including obesity, diabetes, heart disease, and even cancer. The white light emitted by our electronic devices contains high levels of blue light, which tricks our bodies into thinking it's daytime, thus disrupting our natural sleep cycles.

Furthermore, according to studies mentioned by Prevent Blindness and the American Academy of Ophthalmology, sustained exposure to blue light could contribute to long-term vision issues such as cataracts and age-related macular degeneration (AMD). This is particularly concerning given our increasing reliance on electronic devices in our daily lives. To protect your eye health, it's recommended to limit exposure to blue light, especially during the evening hours. Using blue light filters on your devices or wearing blue light blocking glasses can also help mitigate the harmful effects of blue light.

Blue light blocking glasses, also known as computer glasses, feature blue light filtering lenses designed to shield your eyes from the potentially harmful blue light emitted by computer screens and other digital devices.

Here are the benefits of blue light blocking glasses:

• Minimize glare from computer screens and digital devices.
• Reduce eye strain and fatigue caused by prolonged screen time.
• Enhance focus and visual clarity during computer use.
• Improve sleep quality by mitigating the impact of blue light on circadian rhythms.

When buying blue light glasses online, you have two options based on your needs. For non-prescription blue light glasses, simply select your preferred frames from our collection, and during the lens customization, choose "non-prescription blue light glasses."

If you need prescription blue light glasses, ensure you have a valid, non-expired prescription from your eye doctor. Once you have the prescription, pick your preferred frames from our collection and customize your lenses. During lens customization, select the type of prescription lenses you require (single vision, progressive, or reading lenses) and include the blue light blocking feature in the next step.

This streamlined and simple process allows you to easily personalize your blue light glasses to meet your specific needs. Enjoy superior protection and style with your new pair of Kraywoods blue light blocking glasses!
