Should you fly in a plane if have broken blood vessel your eye?

It's generally recommended to avoid flying within 24 to 48 hours of experiencing a broken blood vessel in your eye.

Here are a few reasons why:

- Changes in cabin pressure. When an aircraft ascends or descends, the cabin pressure changes rapidly. This can cause the air inside your eye to expand and contract, which can put additional strain on the blood vessels in your eye. This could potentially cause a broken blood vessel to bleed further or even rupture.

- Dry air. The air inside an aircraft cabin can be very dry, which can irritate your eyes and make them more prone to damage.

- Recirculated air. The air inside an aircraft cabin is recirculated, which means it's not constantly being replaced with fresh air. This can increase the risk of exposure to airborne irritants, such as dust, pollen, and bacteria, which can further irritate your eyes.

- Other passengers' coughing or sneezing. When someone coughs or sneezes, they can release tiny droplets of fluid that can contain viruses or bacteria. These droplets can travel through the air and potentially infect your eyes, causing additional irritation or even an infection.

If you have a broken blood vessel in your eye and you're considering flying, it's important to talk to your doctor first. They can assess the severity of your condition and advise you on whether it's safe for you to fly.

Here are some tips for flying with a broken blood vessel in your eye:

- Choose a nonstop flight if possible. This will reduce the number of times you have to ascend and descend, which will minimize the changes in cabin pressure.

- Stay hydrated. Drink plenty of fluids before, during, and after your flight to help keep your eyes moist.

- Use a saline eye drop solution. This can help to soothe and lubricate your eyes.

- Avoid alcohol and caffeine. These substances can dehydrate you and make your eyes more dry.

- Wear sunglasses or protective eyewear. This can help to protect your eyes from dust, pollen, and other irritants.
