What is the thickening of the lens called?
The thickening of the lens is called presbyopia. This condition occurs with age and results in difficulty focusing on close-up objects.
When the lens loses its elasticity and can no longer bring the objects into focus the condition is known as?
Presbyopia. It is a common age-related condition where the lens of the eye becomes less flexible, making it harder to focus on close objects. This typically occurs around middle age.
When the lens loses its elasticity and can no longer bring near objects in focus what is the condition?
The condition is called presbyopia. It is a natural part of aging where the lens of the eye becomes less flexible, making it harder to focus on close objects. This typically occurs around age 40.
When does a convex lens act as a diverging lens?
A convex lens acts as a diverging lens when the light passing through it diverges rather than converges. This typically occurs when the object is located very close to the lens or when the light rays are not parallel to begin with.
Why does the lens loosen with age?
As we age, the proteins in the lens of the eye can degrade and become less flexible, leading to a condition called presbyopia. This results in difficulty focusing on close objects and can make the lens feel like it is no longer as firm or resistant to changes in shape. Age-related changes in the muscle that surrounds the lens can also affect its ability to change shape for focusing, causing the lens to feel looser.

At what age does the hardening of the eye's lens usually occur?
The hardening of the eye's lens typically occurs around the age of 40, a condition known as presbyopia. This makes it difficult to focus on close objects and can be managed with reading glasses or corrective lenses.
What changes occur in the lens's protein during the aging process?
As people age, degenerative changes in the lens's proteins occur.

Presbyopia. It is a common age-related condition where the lens of the eye becomes less flexible, making it harder to focus on close objects. This typically occurs around middle age.
How does light go through a lens?
Light goes in the lens, refraction occurs, and the light exits the lens.
Who invent the bifocal lens?
Benjamin Franklin is credited with inventing the bifocal lens in the 1780s. He designed the lens to help address his presbyopia, a condition that makes it difficult to focus on close objects as people age.
What age is Emphysema seen in?
Emphysema occurs more often in people 65 years of age and older
What is meant by the term 'lens flare'?
A lens flair occurs in photography when unwanted light shines into the camera and shows up in a picture. This occurs often when shooting pictures with the sun in the background.

Why do humans eyes have to blink?
The lens of the eye needs to stay moist, so blinking replenishes that dryness of the lens. Blinking also occurs in the event of debris getting on the lens of the eye.
Is there right age to wear contact lens?
at least 7 years of age
