Why Do Some People Think Blue Light Glasses Alter Colors?
Some people think blue light glasses alter colors because these glasses often have a yellow tint. This tint can affect how colors appear, particularly shades of blue.
According to the American Optometric Association, blue light is part of the visible light spectrum. It has a short wavelength, which means it carries more energy compared to other colors.
The perception of altered colors is primarily due to the yellow tint in many blue light glasses. This tint filters out a portion of blue light, which can lead to a warmer, yellowish perception of the environment. Thicker or darker lens tints may intensify this effect. Additionally, anyone accustomed to seeing colors in their natural spectrum may notice a shift when wearing tinted lenses.
Blue light glasses may use a coating called anti-reflective coating to reduce glare. This coating can sometimes introduce minor optical aberrations, which may also impact color perception. Optical aberrations are imperfections in lenses that cause distortion, resulting in a change in how we perceive colors.
Specific conditions that can contribute to the perception of altered colors include poor lighting environments or when viewing screens that emit high levels of blue light. For example, if a person shifts from a brightly lit environment to a dimmer one, and then puts on blue light glasses, they may notice a more pronounced yellow tint in their vision. Another scenario is if someone wears glasses with a significant blue blocking capability while viewing a digital screen. This could further enhance the perception of yellowish colors.
Are All Blue Light Glasses the Same in Terms of Tint?
No, not all blue light glasses are the same in terms of tint. While many blue light glasses have a yellow tint designed to filter blue light, the degree of tint varies by brand and product. Some glasses may have a more substantial yellow hue, while others may feature a minimal tint, depending on their intended use and design.
Typically, blue light glasses come in two main types regarding tint: those with a noticeable yellow tint and those with a clear lens. Glasses with a significant yellow tint are better at blocking blue light and may be ideal for individuals spending long hours in front of screens. On the other hand, clear lens versions may block a lesser amount of blue light while maintaining a more neutral appearance. Both types aim to reduce eye strain but cater to different preferences and needs.
The positive impact of blue light glasses includes reduced eye strain and improved visual comfort. A study published in the Journal of the American Optometric Association (2020) found that 73% of users reported decreased eye discomfort after using these glasses.
