Invisible Ink Glasses

If you are a poker player who wants to see the marked cards clearly, the invisible ink glasses can be very helpful. These glasses have a special red filter in the lens which will help you see the invisible markings on the backside of the marked decks.

During the WWII, countries worked hard to develop invisible inks that would keep them one step ahead of their enemies. Ideally these inks should be odorless, could not be developed by heat, iodine or ultraviolet light, and would only be visible by careful visual inspection or olfactory testing.

Infrared sunglasses

While UV rays are often considered the most dangerous part of the sun’s radiation, infrared rays can also cause serious damage to your eyes. Thankfully, some sunglasses now offer protection against these harmful rays, which could save your vision and prevent long-term eye damage.

For example, Vuarnet sunglasses have IR filters built right into the lens that block 95% of near infrared radiation. They’re a great option for outdoor use during the day.

Another way to protect your eyes from infrared rays is to wear sunglasses that block both UVA and UVB light. Look for a label that says “UVA/UVB” or ask your eye doctor for recommendations on what kind of sunglasses to choose.

Infrared rays aren’t as well-known or as damaging as UV rays, but they can still cause eye problems for people who spend a lot of time outdoors. This is why many Marshall Protocol (MP) patients require a special type of sunglasses that blocks IR rays.

Clear glasses

Clear glasses are one of the most popular frame trends for prescription glasses. They’re a flattering, understated option that lets you flaunt your unique style.

They’re also a great accessory for special occasions, such as weddings or parties, since they go with most outfits. And they’re a good choice for people who don’t want to have an opaque or patterned frame in their peripheral vision or who dislike having a colored frame competing with their makeup or hair.

When you wear an outfit with darker colors, clear frames blend in. That’s why it’s important to choose a softer palette around the eyes when building an outfit with clear glasses.

Styling clear frames can be a bit tricky, so it’s helpful to know the correct way to do it. The first step is to find the right shape for your face. Round faces should get square or rectangular frames to make them look slimmer.

Infrared contact lenses

Invisible ink glasses are one of the best tools to read marked poker cards without being busted out. They can also help you see better in dimmed lighting conditions.

University researchers have created a super-light, super-thin material that detects infrared light, which could make night-vision contact lenses possible. The material is based on graphene, which has been shown to be very effective at infrared detection.

In addition, it is able to undergo changes in its chemical structure, thermal properties, and water content. It has been reported that dehydration and rehydration of soft-lens materials lead to significant changes in their physicochemical properties. Moreover, water plasticizing of these materials can cause them to lose some of their transport properties. These fluctuations are related to the molecular dynamics of these materials and their reaction to chemical changes in their environment. These factors can be evaluated by a spectrophotometric technique and a Fourier Transformed Infrared Spectroscopy (FTIR) method. These techniques can provide a good basis for the study of the stability of soft-lens materials.

UV glasses

Whether you’re shopping for sunglasses or prescription glasses, you can add UV protection to protect your eyes from the sun’s harmful rays. This special treatment makes it easier to see in bright-light conditions, lessens the amount of squinting you have to do, and can protect your eyes from the development of cataracts, eye-surface problems like pterygia, and macular degeneration.

Glasses with photochromic lenses contain organic compounds that change their structure in response to UV light. When the dyes are exposed to UV rays, they absorb more visible light and darken the lenses.

Blue-light blocking glasses filter out the blue wavelengths of light produced by digital screens and other artificial sources. These lenses help reduce eye strain and may improve your sleep quality.
