We will continue to test the top performing glasses to see how they perform over time. A board-certified ophthalmologist from our Medical Expert Board also reviewed the contents of this article for medical accuracy surrounding blue light blocking glasses and the effectiveness of different materials and tints. Throughout the test, we paid close attention to how the glasses fit in terms of size and weight, how it felt to wear them for long periods of time, and how clear the lenses were or how any tint affected our clarity of vision. Our editors wore 20 pairs of blue light blocking glasses for one week and evaluated how their eyes felt after spending several multi-hour sessions using screens. To choose the best blue light blocking glasses you have to consider your prescription needs, when and where you’re planning to wear your glasses, and-of course-their overall comfort and degree of protection against blue light (and, in some cases, UV light, too). “These can be lenses with prescription or without… people who feel stress or strain upon their vision after looking at computer or phone screens might want to wear them.” “Blue light glasses are glasses with special coatings designed to eliminate the short wavelength of blue light,” says Brian Lojka, OD, an optometrist at Clarkson Eyecare and medical officer of optometry for EyeCare Partners. However, it can also be caused by an eye injury or a medical condition.Blue light is a type of light emitted by cell phones, computers, and televisions-in other words, the same devices most of us spend huge parts of our day using. Heterochromia is the result of a genetic mutation caused by variations in the distribution and concentration of melanin. Like red eyes, heterochromia is rare and effects less than 1% of the population.
Albinism happens when there is a problem with one of the genes inherited from the mother. Only 1% of people have pink and pale red eyes they are typically albinos. They are most common in Northern and eastern Europe. Green eyes originate from areas around the Caucasus Mountains.Īround 3% off people in the world have grey eyes. People are not born with green eyes they usually develop at around 6 months old. Green eyes affect around 2% of people worldwide however, they make up 86% of the population in Ireland and Scotland. Light brown eyes are most common in West Asia, America and Europe. According to World Atlas, 8% - 10% of people in the world have blue eyes.īetween 55% to 79% of people have brown eyes with dark brown eyes being most prominent in Africa, East Asia, and South East Asia. They believe that the first person to have blue eyes had a genetic mutation that caused the body to reduce its melanin production.īlue eyes are most common in the UK, Ireland, Finland and Sweden. Scientists believe that thousands of years ago, everybody in the world had brown eyes. Rare eye colours originate from genetic mutations. Where do rare eye colours originate from?
