Transitions® Photochromic Lenses
When you step outside, it immediately begins to darken. The lenses help prevent harmful blue light from digital devices, screens, and sunlight to help reduce glare and prevent eye strain. They have the function of 100% UV blocking,anti-reflection treatment with blue light protection. They can constantly adapt to changing daylight conditions to reduce excess light and optimize color contrast and polarized light to prevent dazzle. They filter out excess light to provide maximum comfort. And provide high contrast and minimize glare. They provide increased color recognition and depth perception.
Standard vs Premium Progressive Lenses: What Are Their Differences
In the above part, we have introduced some basic information about standard and premium progressive lenses. So, what are their differences? In this section, we will show them.
Compared with premium progressive lenses, standard progressive lenses require large frames. Otherwise, you will limit your near vision. On the contrary, if you prefer small and less noticeable frames, premium progressive lenses are the better choice.
Compared with premium progressive lenses, standard progressive lenses are cheaper. For most people, standard lenses are affordable.
Compared with premium progressive lenses, standard progressive lenses are suitable for most people including children.
Premium progressive lenses are customized to your eyes and offer a wider viewing area than standard lenses.
What does the Drop Ball Test have to do with the eyewear industry?
FDA mandates that eyewear products must ensure their safety. Impact resistance is a basic norm for binding glasses and/or lenses in the United States. The FDA does say that a drop ball test must be performed on every glass lens for prescription use. The FDA-regulated eyewear products are common in the everyday lives of the public, and the FDA considers impact-resistant lenses to be an important part of the safe design of these devices. Today, safety lenses are rarely mentioned in our sales, but in the 1990s, when resin lenses first entered the Chinese market and glass lenses still dominated the market, safety lenses were a pretty important concept. At the time, the hardening technology has not been upgraded, and the resin lens is easy to wear out than the glass lens. The eyewear industry is relying on lightness, safety (anti-impact), comfort (anti-ultraviolet) step by step to achieve the market share of resin lenses from 1% to 100%.
Cheap frames can cause skin irritation.
Some cheap frames may look like more expensive frames. But more often than not, they are made of low-level materials that can cause skin irritation over time. Cheap plastic frames can be bleached by ultraviolet light, leaving the surface rough after months of wear and tear. Cheap metal frames often contain nickel alloy, which can cause skin irritation.
Different Types of Progressive Lenses
The first progressive lenses we want to introduce are computer progressive lenses, which are designed for clear vision in office settings. These lenses are ideal when using a computer for over 4 hours a day and help to reduce eye strain.
Computer progressive lenses are intended for indoor use and should not be worn over your regular glasses. The drawback to this is it requires you to have two separate pairs of eyeglasses.
Change the lens.
If you like your frames, but your prescription changes or the lenses are damaged, you can simply replace the lenses in the existing frames. Most optical shops will let you choose this method to reduce waste and save money. It is recommended that you take the frame to your local store and talk to the team. They will be able to assess the suitability of your eyeglasses and will be able to give you a quote based on your requirements.
Can you wear blue light glasses while driving?
The damage of blue light has a cumulative effect. The longer the exposure time is, the more serious the damage of retinal cells will be, which will eventually lead to irreversible damage of the structure and function of the retina. Once the retina has permanent damage, degeneration will directly affect the metabolism and function of photoreceptor cells, resulting in vision loss. It depends on the glasses you're wearing. The function of anti-blue light glasses depends on the material of the glasses. Some blue light glasses have a special anti-reflective coating, which can reduce glare. These glasses are definitely helpful when driving at night.
