How Does Blue Light Affect the Eyes?

แสงสีฟ้า

Blue light is light in the approximate wavelength range of 380–500 nanometres. It comes from both natural and man-made sources, including sunlight, mobile-phone screens, computers, tablets, televisions and LED lighting. Blue light plays a role in vision and the body’s circadian rhythm. However, prolonged use of digital devices may leave some people feeling visually uncomfortable.

Common Sources of Blue Light

  • Smartphones
  • Computers and laptops
  • Tablets and televisions
  • LED lights
  • Sunlight


Effects Some People May Notice After Prolonged Screen Use

  • Eye fatigue or digital eye strain
  • Stinging or dry eyes
  • Possible disruption to sleep
  • Concerns about retinal health


What Are Blue Light Photochromic Lenses?


Blue light photochromic lenses combine the properties of blue light filtering lenses and photochromic lenses in one pair. They help filter blue light from digital screens and automatically darken when exposed to UV light from sunlight.


How Do Blue Light Photochromic Lenses Work?


Blue light photochromic lenses combine two technologies: a blue light filter to help filter blue light, and photochromic technology to adjust lens darkness according to UV exposure.

  • Indoors: The lenses remain clear or lightly tinted while helping to filter blue light from computers, mobile phones, tablets and LED lights.
  • Outdoors: Photochromic molecules in the lens react to UV light, causing the lenses to darken to reduce sun glare. They gradually return to a clearer state when you move back indoors.


For people looking for prescription lenses with good UV protection, photochromic multi-coated lenses are another option to consider.


What Colors Are Available and Which Light Conditions Suit Each One?

Blue light photochromic lenses are available in several colors. Each color produces a different visual tone and contrast level, so your choice should reflect both your lifestyle and personal preference.

1. Grey Lenses

Grey is a versatile, standard tint. It reduces brightness without significantly changing the colours of objects, helping to provide natural-looking vision. It can suit driving, travelling, regular outdoor use and anyone looking for an all-purpose lens colour.


2. Brown Lenses

Brown lenses can enhance depth and contrast, making surface details or obstacles easier to distinguish. They can suit driving, travelling and outdoor activities in bright light, helping the eyes adapt more comfortably to changing conditions.


3. Green Lenses

Green lenses offer balanced vision by reducing glare while maintaining relatively natural colour perception. They can be suitable for extended outdoor activities, such as walking, cycling or playing sports in the park, helping provide comfortable vision in sunny conditions.


4. Sapphire Blue Lenses

Sapphire Blue is a contemporary blue tint that stands out from classic lens colours. In addition to helping reduce glare, it can suit people who enjoy outdoor activities and want to add more style to their eyewear while retaining the key benefits of blue light photochromic lenses.

Blue Light Photochromic Lenses vs Standard Blue Light Lenses


Both blue light photochromic lenses and standard blue light filtering lenses can help filter blue light from digital screens. Their key benefits and uses are different, however.

Feature Blue Light Photochromic Lenses Standard Blue Light Lenses
Function Filter blue light and automatically darken under UV exposure Filter blue light only
Use Suitable for indoor and outdoor use Best suited to indoor or screen-based use
Price Higher, because two technologies are combined in one lens More budget-friendly
Suitable for People who use screens and spend time outdoors, and do not want to carry multiple pairs People who mainly use screens and spend little time outdoors


Which Should You Choose?

  • Choose blue light photochromic lenses if you regularly use them indoors and outdoors, travel frequently or want one versatile pair of glasses.
  • Choose standard blue light lenses if you mainly use a computer or smartphone and rarely spend time outdoors. They may be sufficient for everyday indoor use.


Price and How to Choose


Blue light photochromic lenses generally cost around THB 2,000–15,000 or more. The final price depends on the lens brand, prescription, material and coatings, such as multi-coating or thinner-lens options. Rather than choosing by price alone, choose lenses that suit your everyday needs and come with reliable after-sales support.

Before getting new glasses, choose a shop that provides professional eye examinations or access to an optometrist, explains lens options clearly, and offers warranty and after-sales care.
