Allergys can cause itchy eyes.
To treat a foreign particle in the eye, first, avoid rubbing the eye, as this can cause further irritation or injury. Rinse the eye gently with clean water or saline solution to flush out the particle. If the particle does not come out easily or if irritation persists, seek medical attention from an eye care professional to prevent damage. Do not attempt to remove embedded particles yourself.
The particle size of gneiss can vary, but it typically consists of medium to coarse-grained minerals that are visible to the naked eye. Gneiss is a metamorphic rock formed from the recrystallization of pre-existing rocks under high heat and pressure, resulting in a distinctive banded texture.
A tiny particle is a very small piece of matter or substance, such as a molecule or atom. These particles are often smaller than can be seen with the naked eye and can be found in the air, water, or soil.
an alpha particle
A colloid is not a subatomic particle.
I have a dust particle lodged in my left eye.

A 20 micron particle is not visible with the naked eye. The smallest particle visible to the naked eye is 40 microns. To give you some perspective, a piece of hair's width can range from 40 to 120 microns.
100 um
The smallest particle that can be seen by the naked eye through a microscope is a single-celled organism like an amoeba or a paramecium. These organisms are typically around 0.1 to 0.5 millimeters in size, which is within the range of visibility for the human eye through a microscope.
I should say so! I would go to a eye doctor if I were u. Unless you've had it sense you were born.
Oh, dude, the smallest particle size visible to the naked human eye is around 40 microns. But like, who's really out here measuring particles with their eyeballs, am I right? Just stick to admiring the stars in the sky and leave the tiny stuff to the microscopes.
Macroscopic things which could be seen by naked eye and under visible wavelength of light are considered opposite to Elementary particles !
The cornea
Yes. Go to an ophthalmologist.
They pass from particle to particle by vibrating the particle. When the particle touches another particle, it transfers the sound energy to that particle. Hence the Sound Wave.
A particle is an atom which cant be seen by the naked human eye, everything is made up of: in solids; gasses and liquids. Each atom contains electrons, protons and neutrons, which is what gives each particle its properties. Solids tend to have more compact particles where as gasses have less.
