Pupil:
The pupil is the black circular opening in the center of the iris. It allows light to enter the eye and reach the retina.
Lens:
The lens is a clear, flexible structure located behind the iris. It helps to focus light onto the retina.
Retina:
The retina is a layer of cells behind the eye that includes photo receptor cells called rods and cones. These cells convert light into electrical indicators that are sent to the brain through the optic nerve.
Optic Nerve:
The optic nerve carries visual information from the retina to the brain.
Functions of the Human Eye
The human eye is an exceedingly complicated organ, and it plays numerous features to allow us to look at the world around us.Here are some of the main functions of the human eye:
Refraction:
The attention's cornea and lens paintings collectively refract or bend incoming mild, so that it could be focused onto the retina.
Sensing Light:
The retina contains cells called rods and cones, which are sensitive to light.
Age-associated Macular Degenern:
Age-associated macular degeneration (AMD) is a situation that influences the vital part of the retina, leading to imaginative and prescient loss.
Diabetic Retinopathy:
Diabetic retinopathy is a circumstance that occurs in humans with diabetes, where the blood vessels inside the retina become broken, leading to imaginative and prescient loss.

Glaucoma
Glaucoma is a group of eye conditions that damage the optic nerve, leading to vision loss. Treatment options for glaucoma include eye drops, laser therapy, and surgery. The goal of treatment is to lower the intramuscular pressure in the eye, which can help to prevent further damage to the optic nerve.
Macular Degeneration
Macular degeneration is a common condition that affects the central part of the retina, leading to vision loss. There is no cure for macular degeneration, but treatment can help to slow its progression. Treatment options include injections of medication directly into the eye, laser therapy, and dietary supplements.
