Riboflavin is generally considered safe, even at high doses. Riboflavin is water soluble meaning that the body does not store it and expels it via urine, often causing a bright yellow color.

Yes, since one of the ingredients is a blood thinner you should discontinue use of Preventa Migraine at least one week prior to surgery.

Yes, it is perfectly safe to ingest the contents of Preventa Migraine without the capsule in food or drink.

Not all Butterbur remedies are the same and not all of them are safe. The Butterbur plant in its un-purified powder form contains natural pyrrolizidin alkaloids (PAs) which may cause liver damage or liver cancer. Preventa Migraine is PA free, we use Butterbur Root with the PA's removed from the extract via non-chemical ion exchange, which removes nothing from the extract except the PAs and 2 to 3% of its minerals, ensuring the highest quality product with less than 1 ppm of PAs. Preventa Migraine is also manufactured in our GMP certified facility located in the United States.

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.

Preventa Patches are made from a plant-based cooling hydrogel. Cooling hydrogel is a type of gel that is made primarily from water and has the ability to absorb and retain a large amount of water. This gel is used in various products like cooling patches, head strips, and skincare products.

The hydrogel has a cooling effect when applied to the skin, which can help soothe inflammation, reduce swelling, and provide relief from pain or discomfort. The cooling sensation is due to the evaporation of water from the gel, which draws heat away from the skin. Cooling hydrogels are often used for relief from headaches, fever, sunburn, and muscle aches.

To use the strips, simply peel off the backing and apply the adhesive side directly to your forehead or temples. The cooling effect will begin immediately and can last for several hours. No refrigeration is required, but for an enhanced cooling effect, you can chill the strips in the refrigerator before use.

No, the hydrogel cooling head strips are designed for single use only. Once the cooling effect diminishes, dispose of the strip and use a new one if needed.

The head strips are lightly scented with mint. The refreshing mint scent is intended to provide a soothing and invigorating experience while the cooling effect helps alleviate discomfort.

The cooling effects of the head strips can last for up to 8 hours. However, the duration may vary depending on individual body temperature and environmental conditions.

Yes, the head strips are safe for use on children. However, it is recommended to consult with a healthcare professional before using them on young children or infants.

Do not apply the head strips to broken or irritated skin. If you experience any discomfort or skin irritation while using the strips, remove them immediately and consult a healthcare professional if necessary.

Store the head strips in a cool, dry place away from direct sunlight. If you prefer a stronger cooling sensation, you can store them in the refrigerator, but do not freeze them.

It is generally safe to use the head strips during pregnancy, but it is always best to consult with your healthcare provider before use.

There are 18 individually wrapped head strips in each box of Preventa Patches.
