The Best Blue Light Filtering Lenses Today

Modern life exposes people to many different light sources, from natural sources like the sun to artificial sources like LED lights, fluorescent lights, and screens of digital devices... Among these, some types of light can be harmful to the eyes, such as UV rays and blue-violet light.

• Exposure to UV rays can increase the risk of cataracts – one of the leading causes of blindness in the world.

• Exposure to blue-violet light can increase the risk of age-related macular degeneration (AMD), a condition that causes vision loss commonly seen in older adults.

To better protect the eyes from harmful light sources, blue light blocking lenses have been developed by many well-known brands, with varying prices that can make it difficult for you to choose. The market currently offers many different types of blue light blocking glasses. So, what is the best choice for you?

Let’s explore through the article below with Mắt Kính ĐBP 529!

I. Understanding Blue Light Blocking Lenses
What are blue light blocking lenses?
Blue light is present around us all the time. It includes sunlight and light emitted from electronic devices such as TVs, phones, computers, LED lights...

Blue light includes:

– Cyan blue light: Has a wavelength of 455 – 495nm, beneficial for the eyes.

– Blue-violet light: Has a wavelength of 380 – 455nm, causing many health harms, damaging vision such as dry eyes, blurred vision, eye strain, and even headaches. Prolonged exposure to blue-violet light increases the risk of cataracts and macular degeneration – two causes of blindness and vision loss. Additionally, blue-violet light can disrupt sleep cycles.

Therefore, we need blue light blocking lenses, smart blue light filtering to protect the eyes from harmful rays like UV rays and blue-violet light while still retaining the benefits from cyan blue light, maintaining the body's biological rhythm.

It can be understood that blue light blocking lenses are lenses that can prevent the harmful effects of blue light by a special coating that reflects part of the blue light away from your eyes. Typically, they are divided into two types:

Blue Cut lenses: Designed to eliminate 100% of blue light, including harmful and harmless. Those who are sensitive to blue light can choose this type.
Blue Control lenses: This product still eliminates 100% of harmful blue light. Filters about 20% – 40% of harmless blue light. This is a lens line with many advantages. The only limitation is that the lens color is slightly yellowish.
It can be said that this is a perfect, cost-effective solution to protect the eyes and ensure people have better sleep, even when frequently online on phones, computers...

So, what are the harms of blue light:

According to scientific studies, blue light has higher energy than other lights, combined with its short wavelength, so blue light can penetrate the cornea and lens directly to the retina and damage eye cells.

This affects health many times over and can easily damage retinal cells, eventually leading to the death of visual cells.

Manifestations include:

– Eye strain, dry eyes

– Headaches, insomnia

– Increased risk of macular degeneration

Some blue light blocking lenses have a slightly yellowish tint, while others are clearer. Typically, lenses that appear more yellow tend to block more harmful effects from blue light compared to clearer lenses.

1. Benefits of Blue Light Blocking Glasses
   Using blue light blocking glasses helps reduce eye strain, headaches, and dry eyes
   Limits the increase in nearsightedness
   Easier to fall asleep: If you feel eye strain or have trouble sleeping (especially after prolonged use of electronic devices), you should consider using blue light blocking lenses. "Studies show that wearing blue light blocking lenses 3 to 4 hours before bedtime can help us sleep better and more relaxed."
   Reduces the risk of macular degeneration (AMD) in old age
   It also blocks glare during the day and night and protects against UV rays.
2. Who Should Use Blue Light Blocking Lenses?
   – Blue light blocking lenses are for everyone, including children. They are especially necessary for office workers who frequently interact with computer and phone screens.

– Additionally, blue light filtering lenses are also very useful for those who have just undergone myopia surgery (post-surgery eyes tend to be weak and sensitive to light) because blue light lenses also have the added feature of blocking UV rays when going out in bright sunlight 100%.

However, due to the ability to block some blue light from reaching the eyes, vision through blue-blocking lenses may appear slightly yellow. Those who need color accuracy in images should think carefully before using blue light blocking glasses.
