How does the Eye See Color?

The 6 to 7 million cones in the human retina are responsible for color vision. The cones are photoreceptors concentrated in the central zone of the retina called the macula. The center of the macula is called the fovea, and this tiny area contains the highest concentration of cones in the retina and is responsible for our most acute color vision.

Not everyone sees color the same way, some people are “colorblind“. Color vision deficiency describes a number of different problems people have with color vision. Abnormal color vision may vary from not being able to tell certain colors apart to not being able to identify any color.

It is possible to develop color vision problems later in life. Sudden or gradual loss of color vision can indicate any number of underlying health problems, such as cataracts. Color blindness can occur when changes due to aging damage retinal cells. An injury or damage to areas of the brain where vision processing takes place also can cause color vision changes. If you feel your perception of color is changing, schedule an eye exam.

Successful Contact Lens Use

 

Contact lens wear is quite safe as long as proper lens and storage case care are followed. Improper lens wear and care can put the lens wearer at risk for serious consequences. Sight-threatening microbial keratitis (corneal ulcer) is the most significant adverse event associated with contact lens wear and is largely preventable.

Single-use or daily disposable soft lenses are prescribed to be worn once and discarded. This is the safest lens wearing modality because no lens cleaning, lens care or storage case is required.

The contact lens storage case is the most likely potential reservoir for contact lens related ocular infections. Contact lens cases are not meant to be family heirlooms. Replace the case at least every 3 months.
