Protect your eyes from damage with Crizal Prevencia
by Optoplus / August 2020
With social restrictions linked to COVID-19, we’re spending more time on computer screens, smartphones and tablets than ever before. Many of us are working from home, playing video games online and watching Netflix instead of socializing in person, doing online exercise classes instead of going to the gym, and even students will be doing some or all their courses online this fall.
Harmful effects of blue light
While these technologies are extremely helpful in this unprecedented time, the bad news is they not only cause eye strain but also emit harmful blue light (also called blue-violet light). While the sun is the largest source of blue light, the use of screens as well as modern fluorescent lighting (e.g. LED) contribute to long-term continuous exposure to harmful blue light, which can damage retinal cells and cause eye damage.
Blue light is also a contributing factor to age-related macular degeneration (AMD), the leading cause of blindness in industrialized countries. There is still no cure for AMD, and those at highest risk include older people with a family history or exhibiting signs of AMD.
Furthermore, whether it is sunny, cloudy or rainy, UV light can also damage eyes, just like it damages skin. UV light is everywhere and is reflected off many surfaces, and damage from UV light can occur 365 a year in all weather. The damage accumulates over a lifetime, accelerating eye aging and the onset of many severe eye diseases, such as cataracts, which cause cloudy vision, as well as loss of colour vision.
Thankfully, there are preventative measures that can be taken to protect your eyes from damage from both harmful blue light and UV light. Crizal Prevencia lenses selectively filter out harmful blue light, while letting through essential visible light, which is necessary for acuity and colour perception. Furthermore, the lenses also allow beneficial blue-turquoise light to get through, which is essential for the regulation of sleep/wake cycles, mood, memory and cognitive performance.
Crizal Prevencia lenses are the result of several years of research in collaboration with the Vision Institute in Paris. This research helped develop the first clear lenses that selectively filter blue-violet light and contribute to reducing its potential harmful effects on the eye.
Protecting the most sensitive part of your body (i.e. your eyes) from direct exposure to UV light is crucial to prevent cataracts and eye diseases. This is why Crizal Prevencia lenses also incorporate an E-SPF 50 Index, the highest E-SPF index on clear lenses to protect against premature aging and even cancer. 5-10% of skin cancers occur around the eye and protecting the skin around your eye can also prevent wrinkles caused by UV rays. Crizal Prevencia lenses act like a shield to repel dust and water, resist scratches, shocks and smudges and reduce glare.
Eye health protection is important for everyone all year round. Crizal Prevencia is a safe and effective way to protect and maintain your ocular health.
