Why Choosing Quality Eyeglasses Should Not Be Taken Lightly?
Lens coatings can enhance the durability, performance and appearance of your eyeglass lenses. This is true whether you wear single vision, bifocal or progressive lenses.
The importance of adding a coating to my lenses
No eyeglass lenses — not even glass lenses — are scratch-proof.
However, lenses that are treated front and back with a clear, scratch-resistant coating have a much harder surface that is consequently more resistant to everyday scratching - whether dropping your glasses on the floor or occasionally cleaning them with a paper towel.
Kids' lenses, especially, benefit from a scratch-resistant hard coat for greater durability.
The importance of UV protection
Ultraviolet light is a type of radiation that comes mostly from the sun but can also be created by artificial light sources. Just as UV rays can cause sunburns, they can also damage your eyes.
At the front of the eyeball, the cornea and crystalline lens filter UV rays by absorbing them. This prevents UV rays from penetrating further into the body, but it also means that the cornea and crystalline lens are strongly exposed to the effects of UV rays.
The importance of blue light¹ filtering
We spend many hours per day outdoors and indoors exposed to blue light¹ coming from the sun (even inside through the windows), artificial lighting and digital devices.
As a result, damage to the eye can be done in early adult life for people who spend a lot of time outdoors. Cataracts, which occur when the crystalline lens becomes clouded, have also been found to be related to UV exposure. Time spent under the sun without protection can add up and increase the risk of diseases developing. Kids are particularly sensitive to UV rays, so it is a good idea to protect their eyes when outdoors in daytime.
If you need to correct your vision, many types of sunglasses and eyeglass frames can be fitted with Nikon ophthalmic lenses. With sunglasses that fit your correction power, you will experience eye protection, perfect vision and an accurate perception of colours. Enjoy the view!
The overexposure to intense changing light sources may be uncomfortable.
Nikon has created special light management solutions to filter blue light¹ before it reaches your eyes.
The importance of vision while driving
Wearing the right lenses will make every trip in the car a lot smoother.
When you are behind the wheel, having good vision is fundamental: it keeps you and others on the road safe, and gives you a more comfortable driving experience.
Common factors that can affect a driver’s vision include:
- Bright sunlight
- Headlight glare from oncoming cars
- Reflections or glare on wet roads or snow
- Difficulty with peripheral vision, such as glancing at side mirrors
- Eye fatigue
Driving during the day
Good weather helps us enjoy driving. However, bright light can cause glare, which makes driving more difficult. Eye fatigue is also caused by driving. This happens because our eyes are constantly looking at varying distances such as the road, signs, the navigation system, the dashboard and more.
Driving at night
It is said that more than half of all driving fatalities occur at night. Although general fatigue is likely a major cause, it is also true that everyone has a lower vision capacity at night. Vision can also be easily strained by glaring lights from other cars and traffic lights.
There are many Nikon ophthalmic lenses that can benefit drivers. High-performance Nikon anti-reflective coatings minimize unwanted reflections, so you can focus on the road.
