The unprotected human eye is extremely sensitive to laser radiation and may be permanently damaged from direct or reflected beams. Due to tissue traits, the place of the attention broken by means of laser power depends upon the wavelength of the incident laser beam. The retina, cornea, and lens are the areas maximum generally damaged.
"In navy packages, only some microjoules of laser through the scholars in a 10 to 30 nanosecond pulse can produce a seen lesion. At 150 to three hundred microjoules, a small retinal hemorrhage can arise," said Mr. Stuck. This type of damage will have a devastating impact on a pilot's imaginative and prescient.

Glaucoma is a imaginative and prescient situation that outcomes from harm for your optic nerve, often due to expanded pressure in the eye. It’s one of the most common causes of vision loss in adults and may lead.
NOTE: Laser retinal injury can be severe because of the focal magnification (optical gain) of the eye which is about 100,000 instances. This way that an irradiance of 1 mW/cm2 coming into the eye could be correctly multiplied to a hundred W/cm2 whilst it reaches the retina. More Notes on Ocular Laser Damage

However, even this will be pretty risky if the blinded person is, as the FDA places it, "engaged in a vision-essential pastime" (like riding a car).
Laser irradiation of the eye may purpose harm to the cornea, lens, or retina, relying on the wavelength of the light and the electricity absorption traits.
