How do prism glasses work?
Prism glasses rearrange the images by bending the light and moving the images the eye sees to the desired position. They can align?with what each eye sees, eliminating the double image that the brain interprets. When the images seen by both of your eyes are rearranged, the light is redirected to the right position in the retina of each eye. The brain fuses these two images together to form one clear image.
Many traditional optical stores are complaining about a drop in customer numbers. When we analyze it, we find that the decline in customer numbers is divided into two aspects. The first is the decrease in new customers, which is mainly because the Internet and eye hospitals are fighting for customers from optical stores. The other is the loss of old customers, which is entirely because the optical store did not do the best service, especially the after-sales service.
Is blue light blocking worth it?
There are two main problems with anti-blue glasses currently on the market. One is that the place to be prevented is not preventable, and the other is that people have color casts due to wrong protection and aggravate visual fatigue. Studies have shown that our eyes are the most intolerant of blue light in the 400-440 nanometer band. Therefore, current manufacturers mainly block blue light in this band when producing anti-blue glasses. However, the blue waveband of electronic products is between 450 nanometers and 490 nanometers, so most anti-blue glasses have little protection in this waveband. In addition, the blocking rate of anti-blue glasses is 20%~30% to achieve a good anti-blue light effect, but now the blocking rate of anti-blue glasses on the market has basically reached 80%~90%. All in all, these blocking blue light glasses cannot prevent the blue light in the 450-490 nanometer band, and their high blocking rate will also cause a color shift, which makes people more likely to have eye fatigue and headache.
In daily life, the intensity of blue light is low, not enough to cause damage to the fundus, so ordinary people do not need to wear anti-blue glasses unless they are working in extremely strong light conditions or working in special environments. To protect the eyes, it is more important for people to develop good eye habits. For example, wear a pair of suitable glasses and read insufficient light and at an appropriate distance. Avoid using electronic products for a long time. Take a break for 20 to 30 seconds every 20 to 30 minutes, and look at the distance regularly. If you have dry eyes while reading the electronic screen, remember to blink to 12 times per minute. It is best to wear sunglasses when outdoors.
Compared with single vision glasses, bifocals are multi-focal glasses.
Compared with single vision glasses, bifocal glasses, trifocal glasses belong to multi-focus glasses, and the types of trifocal glasses are diverse. When choosing the optical properties of a trifocal lens, it can be thought that the lens is made up of three different lenses: the main lens, the distal optic regions, two appendages. One for the distance and one for the proximal area.
The Pros of Progressive Lenses
In this section, we will show you the benefits of progressive lenses.
One of the major advantages of progressive lenses is that the design of progressive lenses blends the prescription. There is no image jump or visible line on the lens. This enhances your comfort with your lenses and can be safer when performing tasks such as driving.
With progressive lenses, you don’t have to switch other glasses frequently. Progressive lenses correct distance, intermediate, and reading vision within one lens. So, it can bring you great convenience.
What Is Photophobia?
There are a lot of reasons causing our eyes discomforts, such as moving between indoors and outdoors on bright sunny days, staring at computer screens all day, driving at night, or watching TV. If the discomfort worsens over time with accompanying symptoms such as intense pain, excessive squinting, excessive tearing or burning sensations, it may become an eye condition called photophobia or light sensitivity.
One of the symptoms of photophobia is intolerance of light. To some degree, most of us are sensitive to bright or fluorescent lights, but those suffering from photophobia may experience a range of symptoms - from minor or mild irritation to serious debilitating reactions. The symptoms can include dizziness, headaches, migraines, server eye pain, excessive blinking, blurriness, and eye inflammation.
So, they are a few ways to combat photophobia.
