Introduction to the Eye

Eye health is an important part of overall health. It’s crucial to childhood development and independent aging for adults. Most people depend on clear vision. It helps them participate in their occupation, hobbies, and even to perform most everyday tasks. If any part of your visual system is not working, or not conveying the appropriate messages to your brain, vision suffers. To understand how vision is possible, check out our video below.

Our eyes allow us to appreciate the beauty of the world, experience the joy of learning new activities, and undertake new adventures. Knowing the anatomy of your eyes and having regular exams is the best way to keep your eyes healthy and your vision intact.

Parts of the Eye

The sclera (the white part of the eye) is the opaque, fibrous, protective outer layer.

The pupil is the hole located in the center of the iris. It allows light to enter the eye. The pupil appears black because light rays entering the pupil are absorbed by the tissues inside the eye. Or they are absorbed after diffused reflections within the eye.

The iris is a thin, circular structure in the eye. It controls the diameter and size of the pupil. The color of the iris is often referred to as eye color.

The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea with the anterior chamber and lens refracts light with the cornea. This accounts for approximately two-thirds of the eye’s total optical power.

The crystalline lens is a transparent and biconvex structure. Along with the cornea, it helps to refract light to focus on the retina. By changing shape, the lens functions to change the focal distance of the eye. This happens so that it can focus on objects at various distances.

The retina is a light-sensitive layer of tissue lining the surface of the eye. It captures light sent through the cornea and crystalline lens. It then creates an image by triggering nerve impulses that pass to various visual centers of the brain via the optic nerve.

The macula and fovea are small areas within the retina that contain the rods and cones. These structures determine the color and shape of the image you are viewing.

We are happy to be back seeing routine eye care! When you come in for your next appointment you will see we have made several changes to prevent the spread of COVID-19,  including the following: 

1)  The number of patients we see in a day will initially be reduced.  Both the number of available exam appointments and optical encounters will be kept to a minimum to allow for appropriate social distancing and limit the number of patients in our clinic at any given time.

2) When you arrive for your appointment, we kindly ask you please call our office (651-457-2020) to let us know you have arrived.  Our doors will remain locked for the time being. When we are ready for your appointment, we will meet you at the front door and screen for temperature.  If you have a mask of your own, please bring it along to your appointment.  Otherwise, we will provide a mask if you do not already have one. It will be required that you wear a mask for the entirety of your visit within the clinic. 

3) We will continue curbside dispenses glasses, contact lens and eye vitamins.  If you need to pick up any of these items, please call our front desk and a staff member will bring them directly to your car.

4) We require that patients arrive for their exams alone.  Patients can only be accompanied by one other person if they are either a) a minor or b) have mental/physical disabilities.  Again, any patient or caretaker entering the building must wear a mask.  Any accompanied person will be screened for temperature as well.

5) In addition, all of our staff and doctors will have their temperature checked prior to beginning their work day.  All staff will have proper PPE compliant with new regulations.  Although it may seem impersonal, we at Dakota Eye Care are working and will continue to work tirelessly to ensure the safety of both our staff and patients.  Our new policies in regards to social distancing, clinic hygiene, etc. will be posted for you to review.

We have spent the several weeks ensuring we're in compliance with every CDC hygiene guideline for safety of our doctors, staff and patients.  We are excited to get back to work, but in the safest environment possible.  If you have any questions on our new protocols, do not hesitate to ask.  We hope to see you soon and please stay safe!
