Blue light is a type of light that is emitted by screens, like phones, computers, and TVs. This type of light disrupts sleep and causes eye strain. To help combat these effects, some companies make blue light blocking lenses. Our optometrists at Family EyeCare at Westchase in Tampa can help you pick the right type of lenses for your individual needs.
What are Blue Light Blocking Lenses?
Blue light blocking lenses are designed to filter out blue light. This type of light is short-wavelength, which means it has more energy than other colors. Blue light affects the body in numerous ways, including:
Disrupting Sleep
The body’s natural sleep cycle is regulated by the hormone melatonin. Melatonin is produced in response to darkness and helps the body feel sleepy. Blue light suppresses melatonin production, making it difficult to fall asleep and stay asleep.
Eye Strain
Blue light can cause eye strain and fatigue. It can also contribute to digital eye strain, a condition that occurs from looking at screens for long periods. Symptoms of digital eye strain include:
- Dry eyes
- Blurry vision
- Headaches
- Neck and shoulder pain
How Do Blue Light Blocking Lenses Work?
Blue light blocking lenses work by filtering out blue light. They are available in various styles, including:
- Glasses – Blue light blocking glasses look like regular glasses but have a special coating that filters out blue light. You can wear them during the day and at night.
- Computer glasses – Computer glasses are designed to reduce eye strain from looking at screens. They often have a yellow tint that helps to filter out blue light.
- Sunglasses – Sunglasses with blue light blocking lenses can help reduce eye strain and fatigue from sun exposure.
How to Choose Blue Light Blocking Lenses
There are a few things to consider when choosing blue light blocking lenses, including:
Type of Lens
There are different types of blue light blocking lenses. Some lenses are designed for specific purposes, like reducing eye strain from looking at screens. You can wear others all day and night.
Level of Protection
Blue light blocking lenses are available in various levels of protection. Some lenses only filter out a small amount of blue light, while others block most or all of it.
Tint
Blue light blocking lenses are available in a variety of different tints. Some have a yellow tint, while others are clear.
