It is a normal condition of aging, generally resulting in the need for reading glasses.
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.
which organisms have more than one lens in their eyes ?
a lens magnifies an object by using the pupal of your eyes and the glass from the lens to look up close. a lens magnifies an object by using the pupal of your eyes and the glass from the lens to look up close.
The medium lens on the nosepiece of a microscope is typically the 10x objective lens. This lens is often referred to as the "low power" lens and is used for general observation and initial focusing of the specimen.
When using a 100X objective lens, you typically want to use a high numerical aperture (NA) condenser lens to match the high NA of the objective lens. A condenser with a NA value equal to or greater than the NA of the objective lens (typically around 1.4) is recommended for optimal resolution and contrast in microscopy.

The results of laser cataract surgery are typically long-lasting and often permanent. Once the cataract is removed and replaced with an intraocular lens, your vision should remain clear. However, it's important to continue regular eye check-ups as your eyes may change over time.
