About Us

What is the significance of eye protection?

The significance of eye protection extends far beyond a mere shield against external elements; it encompasses a holistic approach to safeguarding one of our most invaluable senses. Here are key aspects highlighting the importance of eye protection:

  • Vital Sense Preservation – Our eyes serve as our primary means of perceiving the world. Protecting them ensures the preservation of this vital sense, allowing us to navigate and interact with our surroundings effectively.
  • Guarding Against UV Radiation – Ultraviolet (UV) radiation, often underestimated, poses a considerable threat to eye health. Eye protection acts as a barrier against these harmful rays, reducing the risk of conditions like cataracts and macular degeneration.
  • Long-term Vision Health – Consistent eye protection practices contribute to long-term vision health. Regular use of UV-protective sunglasses and adherence to eye care routines become instrumental in preventing degenerative eye conditions.

At Eyeonce, we believe that eye protection is not merely a precautionary measure; it is a proactive choice that contributes to the overall well-being, functionality, and longevity of our eyes, enriching the way we perceive and interact with the world.

What are the effects of UV rays on the eyes?

  • Ultraviolet (UV) rays, while invisible to the naked eye, can have a range of effects on the eyes, impacting both short-term comfort and long-term vision health. Here are the key effects of UV rays on the eyes:

    • Photokeratitis – UV rays can cause a painful condition known as photokeratitis, akin to sunburn on the cornea. Symptoms include redness, tearing, and a gritty sensation, usually resolving within a day or two.
    • Cataracts Prolonged exposure to UV rays is a significant risk factor for the development of cataracts. This condition involves clouding the eye’s natural lens, leading to blurred vision and, if left untreated, eventual vision loss.
    • Macular Degeneration – UV exposure has been linked to an increased risk of age-related macular degeneration (AMD). This progressive condition affects the macula, the central part of the retina, leading to a loss of central vision.
    • Pterygium UV rays can contribute to the growth of a non-cancerous growth on the eye’s surface called pterygium. This growth can cause irritation, redness, and a feeling of a foreign body in the eye.
    • Eye Cancer – Although rare, prolonged and intense UV exposure is associated with an increased risk of eye cancers, including melanoma, on the surface of the eye.
    • Increased Sensitivity to Light – UV exposure can lead to an increased sensitivity to light, a condition known as photophobia. This can result in discomfort in bright environments.
    • Corneal Sunburn – Similar to the skin, the cornea can also experience sunburn. Symptoms include pain, redness, and a sensation of grittiness.
    • Conjunctival Issues – UV rays can contribute to the development of conjunctival issues, including inflammation and irritation of the eye’s outermost layer.
    • Accelerated Aging of the Eyes – Prolonged exposure to UV rays may contribute to the accelerated aging of the eyes, manifesting as wrinkles around the eyes and a general deterioration of the eye tissue.
    • Aggravation of Existing Conditions – Individuals with existing eye conditions, such as glaucoma or retinal issues, may find that UV exposure exacerbates their symptoms and accelerates the progression of these conditions.

    Protecting your eyes from UV rays is crucial in mitigating these effects. That is why our eye doctors at Eyeonce, Dr. Paik Dong Won and Jung Rae Som, recommend wearing sunglasses that block both UVA and UVB rays, along with other protective measures like hats, can significantly reduce the risk of UV-related eye issues and promote long-term eye health. Regular eye check-ups with them are also essential for early detection and management of any UV-related concerns.
