Migraine Glasses: Black Cat Eye Photochromic

FL-41 migraine glasses are specially tinted eyewear designed to reduce the frequency and intensity of migraines triggered by light sensitivity. The FL-41 tint filters out specific wavelengths of light, particularly blue and green light, that are known to trigger migraines and eye strain.

FL-41 glasses are beneficial for individuals who suffer from migraines, light sensitivity (photophobia), visual stress, or eye strain. They are also helpful for people who spend long hours in front of screens or under fluorescent lighting.

Generally, you can wear FL-41 glasses throughout the day, both indoors and outdoors consult with your eyecare professional for advise on how to wear them. They are designed to provide comfort and protection from light-triggered migraines and eye strain.

Yes, FL-41 glasses are suitable for children, especially those who suffer from migraines or light sensitivity. It's important to choose a frame size that fits comfortably on a child's face.

To keep your FL-41 glasses in good condition, clean them regularly with a microfiber cloth and lens cleaner. Avoid using harsh chemicals or abrasive materials. Store them in a protective case when not in use.

Most people do not experience any side effects from wearing FL-41 glasses. However, some individuals may need a short adjustment period to get used to the tint. If you experience discomfort, consult with your eye care professional.

Photochromic lenses are eyeglass lenses that automatically adjust their tint in response to changing light conditions. They darken when exposed to ultraviolet (UV) light, such as sunlight, and return to their prior state when indoors or in low light.

Photochromic lenses contain special molecules that change structure when exposed to UV light. This change in structure causes the lenses to darken, providing protection from bright light and glare. When the UV light is removed, the lenses return to their prior rose-colored state.

"Transition" is a brand name for a type of photochromic lens. While all Transition lenses are photochromic, not all photochromic lenses are Transition lenses.

The time it takes for photochromic lenses to adjust varies depending on the brand and the intensity of the UV light. Generally, it takes about 30 seconds for the lenses to darken and as little as a minute to return to rose.

Yes, photochromic lenses provide 100% UV protection, helping to shield your eyes from harmful UV rays whether the lenses are rose-colored or darkened.

TAC (Tri Acetate Cellulose) sunglass lenses are made from a type of plastic that is lightweight, durable, and offers excellent optical clarity. They are commonly used in polarized sunglasses to reduce glare and improve visual comfort in bright conditions.

TAC lenses provide several benefits, including:

- **Glare Reduction** Reduces glare from reflective surfaces like water, snow, and roads.

- **UV Protection:** Offers 100% protection against harmful UVA and UVB rays.

- **Impact Resistance:** TAC lenses are more impact-resistant than standard lenses.

- **Lightweight:** TAC lenses are lighter than glass lenses, making them more comfortable to wear for extended periods.

TAC lenses are lighter and offer better optical clarity than polycarbonate lenses. TAC lenses are suitable for many outdoor activities, especially those where glare reduction is important, such as fishing, boating, and skiing. 

Adding a prescription to pre-made photochromic TAC lenses tinted with FL-41 is usually not possible. Here's why:

1. **Manufacturing Process:** Prescription lenses need to be made to fit your vision from the start. Once lenses have a tint and coating, changing them to add a prescription isn't practical.

2. **Material Limitations:** TAC lenses are made from a plastic that might not work well with the equipment used to make prescription lenses.

3. **Optical Clarity:** Putting a prescription in lenses that are already tinted and coated can make them less clear and effective.

4. **Warranty and Quality Control:** Changing pre-made lenses can void the warranty and might not meet quality standards.

Since Eclipse Aura lenses are intended to be used both indoor and outside, they are not polorized. This is due to the fact that most electronic screens already use anti-glare coating, so wearing polorized glasses will make it particulary hard to spot fine details.

Our lenses do provide several benefits, including:

- **Glare Reduction** Reduces glare from reflective surfaces like water, snow, and roads.

- **UV Protection:** Offers 100% protection against harmful UVA and UVB rays.

- **Impact Resistance:** TAC lenses are more impact-resistant than standard lenses.

- **Lightweight:** TAC lenses are lighter than glass lenses, making them more comfortable to wear for extended periods.
