Questions About Sunglasses

Where does UV radiation affect my eyes most?

Another time when UV can damage your eyes is when you are in environments where there is a reflective surface. For instance a road, or snow, water and even sand (glass is made of sand, so this makes sense). These surfaces react as a mirror and horizontally reflect the sun’s UV rays. This can significantly amplify the rays’ intensity. Make sure you always wear sunglasses in these  environments. If you choose polarized sunglasses, they will filter out horizontally reflected light. The special polarized lenses are manufactured to only let through part of the light.

When you go hiking high in the mountains you are closer to the clouds which increases the risk of damage to your eyes and the skin around your eyes due to more UV radiation. The Equator has also more sun strength, so if you live there or spend a lot of time in an area closer tot he Equator you should know that you’re more exposed to harmful radiation.

Avoid tanning beds, certain lamps that are meant to help cure skin conditions (ask your doctor for a better alternative that does not have these UV side effects). Also watch out for photosensitizing prescription drugs

When do I need to wear sunglasses exactly? I always thought it is only a requirement when it’s sunny and the sky is clear

It's logical that you might think that, but unfortunately it's not true. It’s best ​to wear your sunglasses as often as possible, even when it's not sunny. The sun emits damaging ultraviolet (UV) rays that can damage the eyes. On beautiful, sunny days, but also on more cloudy and overcast days. Some of the harmful UV rays go through clouds and can still damage your eyes, even when you’re not aware of it. So make it a habit to wear your sunglasses when you go outside. Or at least as often as possible.

What are my options to prevent UV damage to my eyes and eyelids?

• ​You can limit your time outside during the sun’s peak intensity hours
  
• You should invest in a good pair of sunglasses that block 100% of UV rays. This is the best way to protect your eyes from the sun. Most quality sunglasses have a UV 400 label and will block 99% to 100% of UV radiation. Make sure you don’t pick a model that is too small. These might look cute but do little to protect your eyes. The best sunglasses from UV protection point of view also shield your eyes from UV radiation entering from the sides
• Some contact lenses provide UV protection. This is a nice little feature, but please remember that they don't cover your eyes and eyelids completely. So even if you wear these, you need sunglasses to cover the rest.
• Use specific sunblock made for your face and the area around your eyes. It should be specifically designed and manufactured fort his purpose otherwise it can hurt your eyes or feel very uncomfortable when it gets in your eyes.
  

Questions About Sunglasses - Which sunglasses lens color is best?

There are no specific UV blocking qualities linked to the color of your sunglasses lenses. Different colors do have an effect on how clear you see in certain environments and weather conditions. But for the rest it's just a matter of taste  is a personal choice and doesn't affect how well sunglass lenses protect your eyes from UV light. Amber/brown coloried lenses are popular because they are comfortable to wear and enhance the natural colors least. Also gray is a popular color.

​Darker lens means better UV protection?

This is not necessarily true. Darker lenses block more light compared to lighter tint sunglasses lenses. But they do not necessarily provide more UV protection. High quality sunglasses provide 99 to 100% UV protection, regardless of lens color.

What ​are the different ​types of sunglasses lenses?

Mineral versus Organic lenses

​There are many, many types of sunglasses ​lenses available. For starters there are lenses made from glass (mineral lenses) and lenses made from plastics (organic lenses). They both have their specific benefits (price, durability, safety).

Different colors and tints lenses

Then there are different lens colors and tints. We have written an extensive article on the topic that you should read. Lens color can have an effect on mood and the clarity of your image, based on different environments

​

Polarized lenses

Sunglasses with polarized lenses generally provide greater comfort because they reduce glare from bright light reflecting off flat, often horizontal surfaces. Examples are water, snow, roads and even sand.

Mirrored lenses

These lenses have a reflective coating applied to the front of the lens. This reflective coating limits the amount of light that can pass and prevents it from entering your eyes. In very bright environments this makes for a highly comfortable wear. And they give yhe wearer a very distinct look as the colors are often bright and flashy. They also mask the eyes of the wearer which can be a benefit for some professions and circumstances. Great for outdoor sports such as watersports, mountain biking and skiing

Anti-reflective lenses (coating)

Sunglasses that have anti-reflecti​ve ​lenses, have a special coating applied to the lenses. This coating prevents light from reflecting off the surface of your sunglasses. This reduces glare and ​makes them comfortable to wear. ​

Gradient lenses

Gradient lenses are exactly what the name implies. They are darker colored on the top and are gradually lighter at the bottom of the lens. ​These lenses are ​used often in the car, because they shield your eyes from other passing cars and overhead sunlight​while the lower part of the lens gives ​full visibility on the dashboard inside.

​Photochromic lenses

these adjust their level of darkness based on the amount of ​light they are exposed to. The material reacts to the amount of light. There are also contact lenses with this photochromatic feature. They no not necessarily protect better against UV radiation though. ​

Prescription sunglasses

These sunglasses with corrective lens is made specifically for the wearer. For this you need a prescription. These are available for many eye conditions, including ​presbyopia. ​Almost any type of sunglasses can be made with progressive lenses, bifocals or trifocals. These are made specificially for the wearer and are usually quite expensive. some people therefore choose to just wear their spectacles with a sun cover. This is a larger than usual type of sunglasses that are big enough to fit over your spectacles and block UV light

​

​Does my child need sunglasses too?

Yes, this really is essential! ​Children are more at risk from UV radiation because they spend (or should spend!!) more time outdoor. UV damage builds up over your full lifetime. So the sooner you provide UV protection to your child, the longer he or she will enjoy healthy eyesight. 

​What shades options ​do I have as a spectacles wearer?

Photochromic lenses are an excellent choice for sun protection outdoors if you need corrective lenses. They provide 99 to 100% protection from the sun’s UV rays as standard sunglasses. And they and darken automatically in brighter environments. In ​some cases, photochromic lenses can eliminate your need for a separate pair of prescription sunglasses.

​Are sunglasses for specific sports a scam?

Yes. Sports eyewear in general tends to be safer than regular sunglasses because the lenses and frames are made of special materials that are unlikely to shatter if struck and can give you the benefits of both sunglasses and protective eyewear. Examples are skiing goggles and sunglasses for golfers. Also, certain tints can enhance your vision for certain sports. For example, amber and brown lenses are popular with golfers because they enhance the contrast between the ball and fairways, greens and the sky.

Are sunglasses produced sustainable and ethical?

​This is a question that cannot be answered with yes or no. I know our sunglasses are. They are made with respect for the people who make them and the environment. Products are made from fastgrowing bamboo and from sustainable wood. They are shipped in 100% plastic free packaging.

But there are many, many sunglasses manufacturers in the world. If you buy your sunglasses from a respected brand that has a lot to lose when it comes to reputation, chances are these products are entically made. I recommend you always check the website of the brands you're interested in, to see what they have to say from a CSR perspective.
