Sunglasses have been around for decades, becoming increasingly popular after the Second World War and particularly trendy amongst Hollywood stars. Whilst acting as a clear expression of a person's fashion sense, sunglasses are also an important yet cool way to protect your peepers from the sun's harmful UVs rays.
With various types of lenses available, it's a good idea to seek the advice of a optician or other vision expert when choosing a pair of sunglasses. In the meantime, we would like to share with you four different types of lens coatings that we hope will help influence your decision when browsing for a new pair of shades.
What Are Polarised Lenses?
Sunlight is often reflected from surfaces, such as roads, water or snow. This type of reflected light is referred to as glare and enters your eyes at different angles to normal light. So, although most tinted lenses provide a level of absorption that reduces the brightness of the sun, only a polarised lens can remove intense glare, as it only allows vertical light through to your eyes. This is particularly beneficial if you're an outdoor enthusiast, such as a fisherman, skier or biker, where glare can affect your performance.
What Are Gradient Lenses?
Gradient lenses are great for driving, as they are tinted from the top down and therefore shield your eyes from overhead sunlight. Since the lower half of the lens allows more light through, you will be able to see your dashboard clearly without having to take your sunglasses off. For the same reason, gradient lenses are also popular amongst pilots and as you can tint a lens almost any colour, gradient lenses are great for making a fashion statement.
What Are Blue-Blockers?
Studies have found that spending as little as one hour outside on a normal cloudy day exposes our eyes to 30 times more blue light than spending that time indoors, in front of a digital device. Continual research shows that blue light can cause permanent damage to the human eye, meaning that blue-blockers have become increasingly popular. These types of lenses allow objects to appear sharper by blocking blue light, allowing other colours to focus clearly on the retina.
What Are Mirror-Coated Lenses?
In the 1940s, mirror-coated lenses were favoured by Hollywood stars because they provided a disguise in order to deceive paparazzi. However, if you want to limit the amount of light entering your eyes, you too should opt for highly reflective mirror-coated lenses. They block 30% more harmful UV rays than normal tinted lenses, which is appropriate for those who are particularly light-sensitive. With the advancement of technology, you can buy mirror-coated lenses of any colour so they're great if you want to make a fashion statement.
Even if you're not going abroad this year, the sun can still damage your eyes with its harmful rays!
