Similar to humans, cancer is the leading cause of death among older cats. It is caused by uncontrolled cell growth, and affects a wide range of cell types and organs in the body. Feline cancer initially manifests as a lump or bump on any parts of the body.
Adaptive headlights make driving at night or under low-light conditions safer, by adjusting the car's headlights to curves in the road. Rather than pointing directly at the space in front of the vehicle, they adjust to illuminate the area that the car will occupy next.
Photochromic or adaptive lenses darken when exposed to UV light, such as when you walk outdoors. When you are no longer exposed to the effects of UV, (i.e. walk indoors), the lenses return to their clear state. Transitions lenses are photochromic lenses that block 100% of harmful UVA and UVB rays.
