Best way to reduce the eyes fatigue and dry eyes caused by the lighting for video calls

Best way to reduce the eyes fatigue and dry eyes caused by the lighting for video calls

Editor by tony jing 01/04/2022

        This article is about the use of use ring lighting for video  calls, which can hurt your eyes in various ways such as visual fatigue, dry eyes and other related phenomena. The purpose of this article is to help users solve this problem.

   What causes eye fatigue and dry eyes?

      The main reason is prolonged exposure of the eyes to light when using lighting for video calls, which causes the muscles of your eyes to automatically contract and the pupils become smaller causing a reduction in light intake. When the muscles are tense for a long time, the eyes become fatigued. Eye muscle fatigue causes a drop in the secretion of eye fluid, resulting in dry eyes.

       This article explores three aspects to reduce this visual fatigue and dry eyes:

  • the first is from the perspective of lighting for video  calls
  • the second is the quality of lighting for video  calls
  • the third, movement

       Is it possible completely to solve the problem of visual fatigue? This is not possible; it can only be reduced.

       First off, from the perspective of light, when you have only one lighting for video  calls placed directly in front of you, then the light enters the eyes directly through the pupil. This is the most important aspect, as it is most likely to produce eye fatigue.

      So we still have to solve the problem of getting less light through the pupil from the point of view of light. How do we solve this problem? The first solution entails switching to one-point lighting.

Solution 1 of eye fatigue caused by lighting for video calls

      So I suggest you use this kind of lighting for video  calls which is 45 degrees diagonally above. The disadvantage of this light is that it will make your nose look very straight, your face and neck will be elongated. If you are a very slim person, it will make you a little distorted in the camera. But if you are fat, that’s good; it will make you look a little you’ve lost some pounds. This is our solution in the case of a single lamp, even if you’re on a tight budget and have only one lamp.

     There is actually a better way to do this with two-point lighting. The characteristic of two-point lighting is that one is the main light and the other is the auxiliary light. The main light is positioned 45 degrees to the left, while the secondary light placed 45 degrees to the right of the subject, both towards the face, the height and face flush. In this method, the lighting for video  calls is not focused directly into the eyes. The biggest benefit of two-point lighting is that it creates the illusion of a three-dimensional subject, with a strong beauty effect.

      Therefore, from a light perspective, if you’re using a single lighting for video  calls, it should be positioned 45 degrees diagonally in front of you. if you are using two light sources, then use two-point lighting. Two-point lighting is better than one-point lighting, because the latter causes distortion inside the camera.

Solution 2 of eye fatigue caused by lighting for video calls

      The second aspect is the quality of lighting for video  calls. The most comfortable light color temperature is from 4000K to 4600K. The human eyes are not easily fatigued in this section, so we have to choose a lighting color temperature in the 4000K to 4600K range.

       Most of the available ring lighting for video  calls use blue chips to excite yellow phosphors to form white light, so there is a lot of blue light inside. If you are running a live broadcast or a long video, I suggest you use full-spectrum LEDs. The benefit of a full spectrum LED substantially reduces blue light and is closer to sunlight. “Full spectrum” refers to the light emitted by the lamp, whose spectrum is close to the solar spectrum, especially in the visible light part. The proportion of various wavelength components is similar to that of sunlight, and the CRI of the light is close to the CRI of sunlight. Full-spectrum LEDs are now more expensive, so the cost of lighting is higher, but if you have a long video time, or you are doing live broadcasts, I suggest that you still use full-spectrum LEDs.

Solution 3 of eye fatigue caused by lighting for video calls

      The last method to relieve eye fatigue involves movement. Regular outdoor sports can effectively regulate eye fatigue of both eyes. Ball sports like badminton, tennis, basketball that require the eyes to chase the target, can enhance ciliary muscle relaxation and contraction. Promote eye metabolism and relieve visual fatigue.

conclusion

       In summary, to reduce eye fatigue, the first thing is to change the angle of light. If it is one-point lighting for video  calls, it should be illuminated 45-degree diagonally from the top in front of you, and use two-point lighting for double light source. In terms of light quality, full-spectrum led lighting for video  calls is recommended. The third method consists of exercising more: playing tennis, badminton, basketball and other sports etc.

Best way to reducing reflections formed in glasses is using the newest lighting for zoom meetings

Best way to reducing reflections formed in glasses is using the newest lighting for zoom meetings

Editor by tony jing 01/04/2022

         The objective of this article is to finding a solution to the problem of reflective circles on glasses for people who wear glasses under the lighting for  zoom meetings. Even when the user doesn’t wear glasses, the problem still persists — two small circles on the pupil. 

reflection on eye glasses under lighting for zoom meetings

       When we make a video call, there is a  lighting for zoom meetings  placed directly in front of us, thus forming two very bright reflective circles on the glasses, especially when we are talking, our heads are shaking, so the two apertures are also shaking, causing the picture to be extremely uncomfortable.

 

       Even for those who do not wear glasses, two small circles form inside the eyes. Some people like it while others hate it.

lighting for zoom calls

     The main reason for this is because the light from the lighting for  zoom meetings shines right flat against the eyes, thus leaving a circle of light on the glasses (or eyes), so we have to move the light further away from us to make the reflection disappear.

      The lighting for zoom meetings can be moved to four different positions: up and down, left and right. As the following is a horror film, do not discuss.

      Move the light to the left or right, that is, 45 degrees to the left or 45 degrees to the right to illuminate the face.

45 degrees to the left

 

      This method is used to solve the problem of the two apertures on the eyes or on the glasses. But it also causes a problem: 

  • when lightis shone on the left, the right side of your face will be dark. there will be light on the left side of your face, while the right side is dark. 
  • similarly, when you shine from the right, then the left will appear dark lighton the right side, darkness on the left side. Then the dark places will produce a lot of noise and appears that your skin aging.

    The lighting  for  zoom meetings makes your skin reflect light evenly, causing your skin to be smooth.

    Therefore, I think the solution does not consist of placing the light on the side,45 degrees to the left or 45 degrees to the right.

     We can do this in another way: pulling the light up and shining it down on the face at an angle of 45 degrees diagonally directly in front of the subject.

directly above at an angle of 45 degrees

     Since the light is coming directly from above at an angle of 45 degrees, it will make your nose appear and longer because a butterfly shadow will be formed under the nose. Your eyes will appear more esoteric because there is a shadow that is created under the brow bone, while a shadow is formed under the chin, which also causes your neck to lengthen.  

     This is the method used by many movie actors, especially Audrey Hepburn. In almost all of her photos, lighting is placed directly above her head, and the light shines down.

   If you are slim with long face, you will appear slimer with a longer face. But if you are fat, congratulations, this method is suitable for you.

    In general, most of what we use lighting for zoom meetings for is to make some simple calls to colleagues or friends. If you are not conducting professional lectures, speeches or conducting live event or talking  to customers, a single light is sufficient. If you think, your budget is on the high side, then we will introduce the two-point lighting method. This method is better than the 45degrees method we saw earlier.

    For two-point lighting, you need for two lighting for  zoom meetings: one for the main light, the other for the auxiliary lights. In general, as the light placed at left is the main light, this time it is a little brighter. It is also placed at an angle of 45 degrees to the left. The other auxiliary is placed at an angle of 45 degrees to the right. This time its brightness is only half that of the main light, or even less.

    The advantage of this is that the light is not directed to the lens, and there will be no reflected light, which also eliminates the reflected light.

   Two -points lighting

      Why use two light sources? As we saw earlier, when the left side is illuminated, the right side of the face will be dark state, hence there will be more noise, which gives the skin a very rough appearance. So the right side of the face needs to be illuminated by also placing a light source to at the right.

     So two-point lighting is a better lighting method. It is better than single-point lighting at an angle of 45 degrees directly above facing down, because its light is more uniform. Besides, two-point lighting does not change the appearance of the shape of the human face whereas single-point lighting does.

      Moreover, two-point lighting accentuates the three-dimensional effect of the face, especially in the cheeks thanks to a triangle of lighting. This contrast between light and dark gives the face a sharp and angular form.

conclusion  about  zoom  lights

 

     In summary, there are two solutions to the problem of reflective circles on glasses or on the eyes: For calls between acquaintances, use one-point lighting, which is an inexpensive alternative. For one-point lighting, the light source is placed directly above obliquely at a 45-degree angle facing downward. Although this is not the perfect solution, it can solve the problem of reflective circles. If your budget is flexible, you can use two-point lighting to solve this problem. Two-point-lighting is better than a one-point lighting.
