Q2: Have you heard about the connection between food and eyesight, like the old saying that carrots help you see in the dark? A2: Yes, definitely. I think everyone's heard that from their parents. I know carrots are healthy, but I don't eat them every day thinking about my vision.

Q3: Our project is about producing that healthy molecule, beta-carotene, from yeast instead of from carrots. What's your first reaction to that idea? A3: That's cool. It seems like a smart way to make a lot of it. Is it for making supplements? I guess it could be a more direct way for people to get the nutrient.

Q4: We're researching how this might be connected to pressure inside the eye, which is a different aspect of eye health than just being nearsighted or farsighted. Is that something you're aware of? A4: I've heard the term, like with glaucoma. But since I've never had any problems, I don't really notice or think about the pressure in my eyes. It's not something you can feel.

Q5: Since you have great eyesight, what does "healthy eyes" mean to you on a day-to-day basis? A5: I guess I'm lucky that I don't have to think about it much. For me, it just means my eyes don't feel tired or strained by the end of the day, and I can see everything clearly without any help.

Q6: If our research led to a safe, natural supplement that could help maintain good eye pressure and potentially prevent future problems, is that something you might be interested in? A6: Probably, if it was easy and there was good science behind it. Since my eyes are fine now, I'd think of it more as a preventative thing, like vitamins, to make sure they stay healthy later on.

Q7: What's your opinion on using modified organisms like yeast for health benefits? Does that seem strange or useful to you? A7: It sounds useful. It seems like a modern way to create things we need. If it's done safely in a lab to make something healthy, I think it's a good idea.

Q8: Finally, for our project, we have to explain our work to the public. How would you suggest we make this project sound exciting and relevant to other students like you? A8: I'd lead with the yeast—it's cool that you're programming a tiny organism to do something new. Then connect it to something everyone cares about, like protecting your eyes from all the screen time we have. Frame it like future-proofing your vision.

Q10: Concern? A10: Eye fatigue affecting creativity.

Q1: When you use digital devices for long periods, how do your eyes typically feel? Do you notice any discomfort, even though your vision remains clear? A1: Actually, yes. Even though my sight is sharp, after long online classes or scrolling on my phone, my eyes sometimes feel a bit tired or dry. It's not painful, but I notice it.

Q2: How aware are you of antioxidants or natural compounds—like those found in certain foods—that can help protect your eyes from environmental or screen-related stress? A2: I've heard a little about blueberries and greens being good for your eyes, but I didn't really know why. It's not something we talk about much at school.

Q3: If you learned that a common food ingredient like yeast could be enhanced to produce eye-healthy nutrients, how would that change your view of science in daily life? A3: It would make science feel much more connected to real life—like it's not just in labs, but in things we eat or use every day. That's pretty exciting.

Q4: Outside of diet, what other methods do you currently use—if any—to help your eyes feel refreshed after a long day? A4: I sometimes use blue light filter settings on my devices, and I make sure the lighting in my room isn't too harsh. But I've never tried anything like a supplement.

Q5: How open do you think you and your friends would be to consuming a nutrient-rich food or supplement that came from bioengineered yeast if it was meant to support long-term eye wellness? A5: I think if it was explained clearly and felt safe, we'd be curious. It would depend on how it tasted or how easy it was to take, though!

Q6: Where do you and your peers usually get information about health or wellness? Would you trust a product developed by student researchers like us? A6: We look a lot online—TikTok, Instagram, sometimes health websites. If students our age were behind it, that would actually make it feel more relatable and trustworthy.

Q7: What kind of message or story about our project do you think would resonate most with people your age? A7: Maybe something like: 'Your screen time isn't going away—so here's a natural way to help your eyes keep up.' It's practical, not preachy.

Q8: Finally, is there anything you wish more people understood about what it's like to be a young person dealing with eye wellness in a digital world? A8: A lot of us are aware that screens affect us, but we don't always have good options that fit into our routines. We want things that are easy, natural, and actually work.

Q1: Could you tell us about when you first started wearing glasses and how that experience was for you? A1: "I got my glasses in middle school when I couldn't see the board clearly anymore. At first, I was a little self-conscious, but now they're just part of my daily life - and honestly, I think they've become part of my style!"

Q2: What are some of the biggest challenges or annoyances you face daily because of wearing glasses? A2: Oh, so many! They fog up when I wear a mask, get dirty all the time, and I'm always worried about breaking them during sports. Plus, sometimes they just feel heavy on my face after wearing them all day.

Q3: How aware are you of the connection between nutrition and eye health? Have you ever tried to adjust your diet to help your vision? A3: I know carrots are supposed to be good for your eyes, but I've never seriously changed my diet because of my vision. Honestly, I'm not sure if eating certain foods can actually reverse vision problems once you already need glasses.

Q4: If there was a natural, yeast-based supplement that could help maintain eye health and potentially slow down vision changes, would that be something you'd be interested in trying? A4: Definitely! Especially if it could help prevent my prescription from getting stronger every year. That's something I worry about - having to get thicker lenses each time I get new glasses.

Q5: What concerns might you have about consuming something made from bioengineered yeast? A5: I'd want to know it's completely safe and tested properly. Also, whether it would taste bad or be difficult to incorporate into my routine. But the idea itself doesn't scare me - it sounds like science doing something useful.

Q6: How do you think your experience with vision challenges has shaped your perspective on eye health compared to your friends who don't wear glasses? A6: I definitely think about my eye health more than they do. They take their perfect vision for granted, while I'm always aware of mine because I depend on my glasses so much. It's made me more proactive about protecting my eyes.

Q7: What would be the most important benefit you'd look for in an eye health supplement? A7: Something that could actually stabilize my vision would be amazing. But even just helping with eye strain from all the screen time we have would be valuable. My eyes get really tired after online classes.

Q8: How would you suggest we explain our project to make it appealing to other students who wear glasses? A8: Focus on how it could make life with glasses easier - maybe by reducing how often we need new prescriptions. And emphasize that it's a natural approach coming from unexpected places like yeast, which is kind of cool and innovative.

Q1: What specific eye-related challenges have you experienced from prolonged screen time? A1: I've developed digital eye strain - dryness, occasional blurry vision, and difficulty focusing after long sessions. I've also noticed increased light sensitivity, especially when working night shifts.

Q2: Have you tried any solutions to address these issues? A2: I use blue light filtering glasses and eye drops, but the relief is temporary. I've tried the 20-20-20 rule, but it's difficult to maintain consistency during intensive coding sessions.

Q3: What's your understanding of beta-carotene's role in eye health? A3: As I understand, it's a precursor to vitamin A which supports retinal health. But I'm curious about its specific mechanism for digital eye strain - is it primarily antioxidant protection or something more?

Q4: How would the bioengineering aspect of our project influence your willingness to try such a solution? A4: The engineered yeast approach is fascinating. As someone in tech, I appreciate innovative biological solutions. I'd want to understand the metabolic engineering behind it - what modifications were made to the yeast's carotenoid pathway?

Q5: What safety data would you need to see before considering a supplement from engineered yeast? A5: I'd want full toxicological profiling, including off-target metabolite analysis. Also, how the bioavailable form compares to traditional sources. Third-party verification would be essential.

Q6: How might your technical background shape your expectations for such a product? A6: I'd expect precise dosage information and clear mechanisms of action. I'd also be interested in any potential synergistic effects with other nutrients like lutein or zeaxanthin.

Q7: What practical factors would determine whether you'd incorporate this into your routine? A7: Convenience is key - whether it's in capsule form or easily incorporable into foods. Stability data would be important too - how well the compound survives processing and storage.

Q1: Could you describe the specific eye-related challenges you face in your administrative work? A1: The constant switching between computer screens, paper documents, and digital tablets causes significant eye fatigue. By afternoon, I experience blurred vision and headaches, especially when processing numerical data in spreadsheets.

Q2: What current solutions have you tried to address these issues? A2: I've tried anti-glare screens and adjusted my workstation lighting. Our office provides blue light glasses, but they don't completely solve the problem. I take regular breaks, but the nature of administrative work requires sustained visual attention.

Q3: How familiar are you with nutritional approaches to eye health? A3: I know about carrots being good for eyesight, but I'm unsure about practical ways to incorporate eye-healthy nutrients into my busy schedule. Most supplements are expensive and require consistent daily intake.

Q4: What would be important factors for you in considering a yeast-based nutritional solution? A4: Cost-effectiveness and convenience would be key. As an administrative assistant, I need solutions that fit into my routine without disrupting workflow. Easy administration - perhaps in food formats - would be preferable to pills.

Q5: What safety concerns might you have about bioengineered yeast products? A5: I'd want clear information about government approvals and any potential allergies. Since I handle important documents, I need to ensure anything I take won't cause unexpected side effects that might affect my work precision.

Q6: How might your workplace environment influence your interest in such products? A6: Open office lighting and air conditioning create dry conditions that worsen eye strain. Any solution that could help maintain eye moisture and reduce fatigue would significantly improve my productivity and comfort.

Q7: What evidence would you need to feel confident trying such a product? A7: Simple, clear information from reliable sources - maybe testimonials from other professionals with similar eye strain patterns. Clinical data presented in straightforward language without scientific jargon.

Q8: How could we make information about our project accessible to busy professionals like yourself? A8: Brief informational materials in break rooms or through workplace wellness programs. Short videos explaining the science simply, emphasizing practical benefits rather than technical details.

Q1: What was it like when you first found out you needed glasses? A1: I was kind of sad. I didn't want to wear them because I thought I'd look different from my friends. Now I'm used to them, but I still don't love it.

Q2: What's the most annoying thing about wearing glasses every day? A2: They slide down when I run in PE class! And they always get fingerprints on them. Sometimes I forget where I put them and I can't see to find them!

Q3: Do you know why people say carrots are good for your eyes? Have you tried eating more of them? A3: My grandma says that! I tried eating more carrots for a while, but I don't think it helped my vision get better. I still needed stronger glasses this year.

Q4: What if you could get eye-healthy nutrients from something like a yummy snack instead of carrots? Would you try it? A4: Yeah, that would be way better than just eating carrots! Maybe like a fruit snack or something? That would be easy to remember to take.

Q5: How would you feel about eating something made from special yeast (like what makes bread rise) that's good for your eyes? A5: That sounds weird but kind of cool. As long as it doesn't taste like bread or smell weird! Would it be in a candy or something?

Q6: What would make you actually remember to take something every day for your eye health? A6: If it tasted good and I could keep it in my backpack. Maybe if my phone reminded me? Or if I could take it at lunchtime with my friends.

Q7: If you could tell eye doctors one thing about what it's like to be a kid with glasses, what would you say? A7: I'd tell them that glasses are annoying when you want to play sports or go swimming. And I wish there was a way to stop my eyes from getting worse every year.

Q1: Zoey, why do you think protecting our eyes is important?
A1: I think it's important because we use our eyes every day to read and play. If my eyes get tired, I can't enjoy cartoons or drawing.

Q2: Do you know some ways to protect your eyes?
A2: Yes! I try not to look at the iPad for too long, and I eat vegetables and carrots because they are good for my eyes.

Q3: What is your favorite activity that needs healthy eyes?
A3: Reading picture books. I love colorful animals in the stories!

Q4: what do you think about eye problems in students today?
A4: Many of my classmates wear glasses because we use computers and phones too much. I think we should spend more time outdoors.

Q5: Have you heard about β-carotene?
A5: Yes, it is a nutrient that helps our body make vitamin A, which is good for vision. I think producing β-carotene is a smart idea!

Q6: What is your favorite food that has vitamin A?
A6: I like pumpkins and sweet potatoes. My mom cooks them in soup.

Q1: Given your academic and research background, you likely spend a lot of time on screens. What are some of the most common eye health issues you've experienced personally, such as dry eyes or eye fatigue? A1: As a PhD student, I spend a significant amount of time reading papers and analyzing data on a computer. I've definitely experienced digital eye strain, which manifests as dry eyes, fatigue, and occasional blurred vision. It's a common problem in academia, and it can be a real distraction when you're trying to focus on complex research.

Q2: From a scientific perspective, what are your thoughts on using a novel method like yeast fermentation to produce beta-carotene? How does this compare to traditional extraction methods from plants, in terms of efficiency or scalability? A2: From a scientific standpoint, using yeast fermentation to produce beta-carotene is a really interesting approach. It offers several potential advantages over traditional extraction from plants. You have a controlled environment, which can lead to higher purity and a more consistent product. Additionally, it could be more scalable and cost-effective, as you're not limited by seasonal harvests or arable land. The challenges, of course, would be optimizing the yield and ensuring the final product is safe and bioavailable.

Q1: In your role in Human Resources, you deal with employee well-being. What are some of the most common complaints or issues related to eye strain and screen time that you hear from colleagues? A1: In HR, we hear about eye strain quite a lot, especially since a lot of our staff work on computers all day. The most common issues are definitely headaches, eye dryness, and general fatigue by the end of the day. People also complain about neck and shoulder pain, which is often related to poor posture when they're leaning into the screen.

Q2: From a consumer standpoint, how would you perceive a health product, like a beta-carotene supplement, that's produced using yeast instead of being extracted from carrots? Would the source matter to you? A2: Initially, the source might be a point of curiosity for me. If a supplement said 'yeast-produced,' I'd want to know more about what that means. My main concerns would be safety and effectiveness. If the company could clearly explain the process and provide evidence that the product is just as good, or even better, than a plant-based one, I would be open to it. I think transparency about the science would be key for a consumer like me.

Q1: In your opinion, what is the most significant challenge in translating a biotechnological breakthrough like this from the lab to a commercially viable product? A1: The most significant hurdle is almost always scaling up production. What works in a small lab flask often faces immense challenges when you move to a large industrial bioreactor. You have to consider everything from optimizing the fermentation process and ensuring product stability to meeting regulatory requirements and achieving a competitive cost-of-goods. The science is one thing, but the engineering and logistics are a whole other challenge.

Q2: As a fellow researcher, you likely spend extensive hours on detailed work, often at a computer. How do you personally handle the physical demands on your eyes, and what methods have you found most helpful for preventing fatigue? A2: Like many researchers, my work involves long periods of screen time. I've found a few simple habits to be very effective. I try to follow the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds). I also make sure my workspace is set up correctly with proper lighting and screen height. These small changes really help in preventing the worst of eye fatigue.

Q3: What's your initial reaction to the idea of using brewer's yeast to produce beta-carotene? What advantages or disadvantages do you see in this biotechnological approach compared to traditional methods? A3: As a researcher, my first reaction is that it's an innovative and sustainable idea. One of the main advantages is the ability to have a controlled, year-round production cycle, which isn't possible with agriculture. This could lead to a very consistent product. A potential disadvantage might be the cost of scaling up and the need for significant R&D to optimize the genetic engineering of the yeast. We'd also need to ensure there are no unintended byproducts in the final extract.

Q4: Beyond the benefits for eye health, what other potential applications of beta-carotene produced by yeast fermentation do you find most intriguing from a research standpoint? A4: I think the possibilities are really wide-ranging. Aside from human health supplements, this technology could be used for food coloring or fortification. You could potentially introduce beta-carotene into everyday foods in a more cost-effective way. It could also have applications in animal feed to improve the nutritional content of livestock products, or even in cosmetics as a natural antioxidant.
