Think about how often you use smart device screens, how often you watch TV or how many hours you work in front of your monitor or laptop. Currently, about 93% of adults use these devices for at least two hours a day, and more than 60% use them five or more hours a day. After just a few hours in front of the monitor, our eyes become tired, with symptoms including a general tiredness, headaches, blurred vision or red, irritated or dry eyes. More than 50% of people who use this type of device experience this type of eye fatigue.

Smart devices and some energy-saving lighting systems emit high-frequency blue light. Research has shown that blue light is particularly important for regulating melatonin in the human body, a process that influences the biological circadian rhythm and overall well-being.
However, on the other hand, there is evidence that long-term exposure to blue-violet light contributes to photo-chemical damage to the retina, increasing the risk of macular degeneration (a phenomenon known as “dangerous blue light”). It has also been shown that exposure to blue light before bedtime can cause sleep disturbances.

It is particularly important that there is adequate filtering of blue-violet light according to its intensity. Filtering blue-violet light at 440 nm and shorter wavelengths has a minor impact on the circadian rhythm while providing protection against macular degeneration.
Lens enhancements for glasses, or so-called BlueProtect lenses, partially reflect blue-violet light from artificial sources, preventing harmful light from reaching the eye. These treatments reduce the transmission of harmful blue light, while maintaining a high level of transmission at the wavelength needed to regulate the cicadian rhythm, and this would be the difference between quality lenses, compared to those that totally reflect light, and induce a mirror effect, the transmissibility of light through the lens is greatly diminished.

The human eye is a work of art of nature. It includes a combination of lenses and muscles that work together to send information to the brain , then transformed into images. Peripheral vision is just a part of our ability to see, and there are a number of very interesting aspects related to this area of ​​vision.

As we always look ahead, many of us assume that central vision is the most important. This is not true. For example, central vision is not essential to the overall view. Only with the periphery we can have a complete picture. It’s amazing how dependent we are, and how much we use it without being aware of it.

The significance of peripheral vision is best emphasized during driving. This means we do not have to turn our head every time we want to see sideways, being able to look forward, but use the side mirrors at the same time without losing our focus on the road, thus avoiding accidents.

Did you know that?

From the scientific point of view, the peripheral vision is that area of ​​the visual field, outside the central vision area. So when we say that “we see the tail of the eye” we are referring to this segment of vision.

• Peripheral vision is an aspect of our safety. It allows us to see objects approaching us sideways to avoid accidents, for example.
• Peripheral vision helps us see at night.
• In the peripheral vision area, we see everything in black and white, but this is not noticeable because the eye movement compensates for this.
• Most people read using only central vision, which prevents them from seeing more than 50% of the text. A peripheral trained view increases the ability to read texts faster.

Each person, with his or her age, begins to be dependent on the use of glasses for the near work. This can create discomfort especially when the person is already wearing eyeglasses for distances and normal activities such as driving, watching TV, shopping or reading a prescription of medicine becomes difficult because it requires the alternation of two pairs of glasses.

To eliminate this discomfort, the solution is progressive lenses. The progressive lens gives you a good view at a distance, close to, but also in the middle, due to a vertical diopter sequence similar to a degrade color. However, there is a wide variety of progressive lenses, suitable for each individual, depending on the type of activity carried out, but also on the budget and its expectations.

How do we choose the right type of lens?

At Best Optic, both optometrists and sales consultants will recommend products related to your activities and lifestyle. From the available portfolio you will be able to choose from the classic variants to the individual ones according to budget and expectations.

Technology and innovations in the field have today produced the lens at the highest level. If in the past lenses were manufactured in series and each wearer had to adapt to the same lens type, today the lenses are built according to the particularities of the wearer.

At the same time, adaptation with progressive lenses will also be influenced by choosing the right frame and meticulousness, and by going through all the steps involving technical parameters, both through classical methods and with state-of-the-art equipment.

At Best Optic, a young, enthusiastic team is waiting for you to offer the perfect solution for a great view.
