Laser light can help wounds heal.
For some people with epilepsy, light sensitivity plays a decisive role – especially when watching TV, playing video games or using smartphones. Attacks are often triggered by flashing or flickering lights.
A British research team has developed a dual-layer liquid crystal lens to repel lightwaves in the highly triggering 660-720nm range. Their prototype, when warmed to 36.5℃, blocks 98% of such lightwaves at room temperatures of up to 26℃.
An integrated sensor monitors the temperature to prevent malfunctions caused by erroneous filtering. Activating the lenses selectively would mitigate the effects of wearing permanently tinted glasses.
The frames could be made from coffee grounds, while an intelligent sensor band has the potential to predict seizures.
