Hello! Thank you for your questions regarding eye health. Let's address both of your concerns in detail.

Firstly, regarding the black flashes you and your brother experienced while watching the news, this phenomenon can be quite alarming. What you described sounds like "visual disturbances," which can occur for various reasons. One common cause is the presence of "floaters," which are tiny specks or strands that float in your field of vision. They are usually harmless and are caused by changes in the vitreous gel inside the eye as it ages. However, if you see flashes of light or sudden changes in your vision, it could indicate a more serious condition, such as a retinal tear or detachment. It's important to note that while your parents may have different opinions about the cause, if you experience these flashes frequently or if they are accompanied by a significant change in vision, it would be wise to consult an eye care professional for a thorough examination.

Now, regarding your second question about the redness and blood vessels in the white part of your eyes (the sclera), this can indeed be related to several factors. Allergies are a common cause of eye redness and can lead to itchy, watery eyes. When you rub your eyes, it can exacerbate the redness due to irritation and inflammation. Lack of sleep can also contribute to eye redness, as it can lead to fatigue and strain on the eyes.
The blood vessels in your eyes can become more prominent when you are tired, stressed, or experiencing allergies. In most cases, this redness will resolve on its own, especially if you address the underlying cause, such as getting more rest or managing your allergies. Over-the-counter antihistamine eye drops can help alleviate symptoms if allergies are the culprit. However, if the redness persists or is accompanied by pain, vision changes, or discharge, it is essential to seek medical attention.

In summary, while the black flashes you experienced could be benign, they warrant a professional evaluation to rule out any serious conditions. As for the redness and bloodshot eyes, they are often related to allergies, fatigue, or irritation and can usually be managed with proper care. Ensuring you get enough sleep, avoiding eye rubbing, and possibly using lubricating eye drops can help improve your symptoms. If you have ongoing concerns or if your symptoms worsen, please consult an eye care professional for further guidance.

Remember, taking care of your eyes is crucial, especially in today's digital age where screen time is prevalent. Regular eye check-ups and being mindful of your eye health can help prevent issues in the future. Thank you for your questions, and I hope this information helps clarify your concerns!
