A broken blood vessel in the eye, also known as a subconjunctival hemorrhage, can be unsightly but is generally harmless and tends to heal on its own within a week or two. While you can't speed up the healing process significantly, there are a few steps on how to heal broken blood vessel in eye fast:

Avoid Eye Irritants: To prevent further irritation, avoid activities that could worsen the condition, such as rubbing your eyes, wearing contact lenses, or exposing your eyes to smoke or chemicals.

Apply Cold Compress: Applying a cold compress can help reduce any swelling and discomfort. Place a clean, cold cloth or ice pack over your closed eyelid for a few minutes, making sure not to apply excessive pressure.

Stay Hydrated: Staying well-hydrated can help promote overall eye health and may contribute to faster healing.

Protect Your Eyes: If you have a subconjunctival hemorrhage, consider wearing sunglasses when outdoors to shield your eyes from bright sunlight and UV rays, which could potentially exacerbate the condition.
