What Are Colorblind Glasses?
Colorblind means that you can’t see the depth or richness of certain color shades. Colorblind glasses are eyeglasses with specially tinted lenses that help a colorblind person to see colors more accurately. Colorblind glasses do not cure color blindness or produce 100% normal color vision. But they enhance and partially correct certain color vision deficiencies of colorblind individuals.
Color blindness is common among people, especially in men. Blindness is an inherited condition, but can also be acquired. It can also occur if the eyes are damaged due to injury or from another disease that affects vision.
Colorblind glasses claim to assist with detecting differences between colors. They also claim to add additional vibrancy to the colors that people with color blindness may not fully experience.
Bifocal Lens
Bifocal lenses have two observation areas separated by visible lines, a larger observation distance area, and a smaller reading area. It may take some time for people who are wearing bifocal glasses for the first time to get used to the lenses. This is mainly due to learning how to move the eyes between the observation distance area and the reading area. Some people will also find that there will be an 'image jump' phenomenon at the visible line between the distance and the reading area, especially for those with limited mobility, who must look down when walking. The best way to get used to bifocals is to wear them as much as possible.
What Are Polycarbonate Glasses?
Polycarbonate was developed in the 1970s for aerospace applications and is currently used for the helmet visors of astronauts and for space shuttle windscreens.
Polycarbonate lenses were introduced in the early 1980s in response to a demand for lightweight, impact-resistance lenses. Since then, polycarbonate glasses have become standard for safety glasses, sports goggles and children’s eyewear.
Polycarbonate glasses are thinner and lighter than regular plastic lenses. They also provide 100 percent UV protection and are up to 10 times more impact-resistance than plastic or glasses lenses.
In addition, Polycarbonate lens provides clearer and more comfortable vision if anti-reflective coating is applied to the lenses, which can eliminate distracting lens reflections that interfere with vision, particularly when driving at night or in other low-light conditions when glare sources are present.
After learning some basic information about polycarbonate glasses, we will show you the advantages and disadvantages of polycarbonate lens.

3 Common Problems with Progressive Lenses
Though progressive lenses are popular to correct some eye conditions, there are also some drawbacks. So, in the following section, we will show you some common problems with progressive lenses.
Dizziness: the three different focal lengths of progressive lenses can make people susceptible to dizziness, as well as vertigo. From long to medium to short distance, the lenses offer a gradient of increasing strength. So, it would have trouble in adapting the glasses for the people who are wearing them for the first time. A common mistake is to look out of the wrong focal length, causing their vision to be blurry and lead to an overall feeling of dizziness.
Peripheral distortion: another common problem of progressive lenses is the way in which they blur peripheral vision. Most glasses cause an initial distortion to vision. However, the three different segments found in these lenses can make that distortion feel more prominent than other pairs of eyeglasses. And most people may need two weeks to adjust to progressive lenses.
Depth perception: Since progressive lenses provide three different prescriptions to see objects clearly for different distances, it is important that you need to move your head instead of your eyes when focusing on objects at different distances. Prior to adjusting to this little nuance, progressive lenses can cause depth perception to feel off.
From the above information, you have known some common problems with progressive lenses. So, you may ask how to adjust the progressive lenses. The most popular way is that you need to wear them frequently.
How Does Photophobia Glasses Work?
The visible light spectrum is made up of all the colors in the rainbow. Red light waves sit to the left; as you move to the right, there is orange, yellow, green, blue. And violet light, with other colors in between. The light resides along the visible light spectrum according to how long their wavelengths of energy are. UV light has the shortest wavelength and red has the longest.
However, UV light carries a significant amount of energy that can damage and burn our eyes. So, the indoor sunglasses for light sensitivity are designed to filter out and block blue-green wavelengths, fluorescent light, LED lighting, bright sunlight and other reflective lights that may affect the eyes.
After wearing photophobia glasses, the number of migraines may be reduced besides the eye damage. So, not only can they protect your eyes from the sunlight, but also can relieve other symptoms.
Hence, if you need a pair of light sensitivity glasses, Koalaeye glasses are recommended. They come in stylish and at a cheap price.
