The Magic of Our Eyes
Sight - the most prized of all human senses. Our inspiration to help people see better, connect better, and live to the fullest.
We marvel at the magic of our eyes, yet we are acutely aware there are many who do not fully experience the wonder of this gift. Nearly 1.3 billion people around the world face impaired vision, and 80% of those cases are preventable with early diagnosis and vision treatment. We are committed to changing these statistics.
We are relentless in our pursuit to help people honor their eyes across their entire lives. Innovation is at the heart of our organization and embedded in all we do. It fuels our discovery and development of new products and also extends to our collaborations, education and community efforts to bring new solutions to those in need.
Nearsightedness, also known as Myopia.
Myopia is a condition where distant objects appear blurry. The myopic eye is slightly longer than normal and is corrected with minus powered lenses.
Uncorrected myopia is the leading cause of distance vision impairment globally.
There are two kinds of farsightedness: Presbyopia and Hyperopia.
Presbyopia is an age-related, decreased ability to see nearby objects, especially in low light. Everyone will become presbyopic, usually starting around the age of 40.
Hyperopia affects people of all ages and is where near and occasionally distant objects appear blurry. The hyperopic eye is slightly shorter than normal and is corrected with plus powered lenses.
Astigmatism is a variation in the curvature of the cornea - the clear, round dome covering the eye's iris and pupil - or in the shape of the eye's lens. Astigmatism results in blurred or distorted vision at all distances, varying with the amount of astigmatism.
Glaucoma usually happens when fluid builds up in the front part of the eye, causing increased pressure within the eye which can damage the optic nerve.
Tears help maintain the health of the front surface of the eye and help to maintain clear vision. Dry eye is a condition in which a person doesn't have enough quality tears to lubricate and nourish the eye.
Dry eye is a common and often chronic problem, particularly in older adults.
Globally, at least 2.2 billion people have a vision impairment, and of these, at least 1 billion people have a vision impairment that could have been prevented or is yet to be addressed
By 2050, 4.8 billion people
(half of the world’s population)
is projected to be myopic
Cataracts are the main cause of preventable blindness worldwide and impacts 100 million eyes
