    Eyeglasses are designed with a focal length to project an image through the lens in your eye onto your retina, not to concentrate all the light into a single point.

    That said, please don’t stare at the sun for 5 continuous seconds. You are likely to cause permanent long-term damage to your retina doing that. Don’t look directly at the sun at all, ever
