Neochrome lenses, also known as photochromic lenses, are lenses that function as normal glasses while indoors and darken upon going outside. While many people are familiar with the term “Transition Lens,” it’s important to note that this specifically refers to a brand of photochromic lenses made by EssilorLuxottica, and not all photochromic lenses fall under this brand.
What are Neochrome Lenses?
Neochrome lenses are eyeglass lenses that automatically adjust their level of tint based on the amount of ultraviolet (UV) light they are exposed to. In the absence of UV light, such as indoors, these lenses remain clear, providing the wearer with unimpeded vision. When exposed to sunlight, they darken, effectively becoming sunglasses to protect the eyes from glare and harmful UV rays. This adaptability makes them an excellent choice for those who move between indoor and outdoor environments frequently.
How Do Neochrome Lenses Work?
The magic behind Neochrome lenses lies in their photochromic molecules. These molecules change structure when exposed to UV light, causing the lenses to darken by absorbing visible light. Once the UV light diminishes, the molecules return to their original state, and the lenses become clear again. This process is both automatic and reversible, offering a convenient solution for vision correction and eye protection in varying light conditions.
The Benefits of Neochrome Lenses
- Convenience: Eliminates the need for a separate pair of sunglasses, making it easier to manage vision correction without constantly switching between glasses.
- Protection: Offers continuous protection against UV rays, which can contribute to cataracts and other eye health issues over time.
- Comfort: Reduces eye strain by adjusting the tint level based on the brightness of the surroundings, which is particularly beneficial for people sensitive to light.
What to Know Before Choosing Neochrome Lenses
While Neochrome lenses offer several benefits, there are a few considerations to keep in mind:
- Adaptation Time: The lenses need a few moments to adjust to changes in light conditions, which might not be instantaneous for every situation.
- Temperature Sensitivity: The speed and extent of color change can be influenced by temperature, with colder conditions slowing down the process.
Are Neochrome Lenses Right for You?
Choosing Neochrome lenses depends on your lifestyle, budget, and specific needs. If you find yourself frequently moving between indoors and outdoors and desire the convenience of not having to switch between prescription glasses and sunglasses, Neochrome lenses could be an excellent choice. However, if you work in environments with fluctuating light conditions or spend a lot of time driving (where UV protection from car windows can affect the darkening process), you may want to consider other options or combine these lenses with other eyewear solutions.
