It doesn't mean that someone sees the world in black and
white.
It's technically labeled as Red-Green color blindness, which means
the world is seen in shades of yellow.
The cones in your eyes (a certain shaped cells in your retina) are
built to pick up different wavelengths of light (think
ROYGBV). So the cones that would pick up reds and greens are
absent or broken.
Found to be a Y-chromosome trait, so it is more prevalent in
males.
Rarely Blue-yellow color blindness is a thing.
pink eye = inflammation of the conjunctiva
conjunctiva = the layer that covers your whole eye
A scratched or injured cornea. Symptoms include redness,
watering, light sensitivity, foreign-body sensation
Can be dramatic or traumatic like being hit in the face or eye by
something, or something as simple as rubbing an itchy eye or
getting something out of their eye.
* If you end up with something in your eye, the best option is to
flush it out with water or saline
Bacteria on your hands or the thing that scratched your eye can
lead to a deeper infection, but most of the time, if you use
caution, it will heal itself rather quickly.
**Solution for light sensitivity: wear sunglasses at night
When the retina detaches from the back of the eye. Sounds awful but it doesn't hurt. The retina a web of nerves in the back of your eye that sends signals to the brain.
Closing curtain sensation is where part of the view of vision will become shadowed as the retina detaches gradually from one side to the other. Floaters also show up if this is happening. (All floaters ARE NOT related to the retina.)
Sudden detachment can be caused by head injuries or sudden
intra-ocular pressure drops (the fluid pressure inside your
eyeball). This sudden detachment is experienced as a flash of
light and then sudden darkness. Sudden or gradual detachment
requires immediate medical attention and can be repaired with
surgery and medical intervention.
Diabetic retinopathy do to chronic damage can lead to retina
detachment. *The risk of retina detachment occurring after an
eye procedure (lasik surgery or cataracts surgery) is skewed for
people with severe nearsightedness, possibly due to a genetic
disposition of having a shorter retina.
Safe to use allergy eye drops long-term?
Answer: Sure! The only problem is that chronic use can
lead to your body not responding to the same med over and over as
well. So, to avoid this, swap between drops and allergy tabs
- based on if you're experiencing "eye only" allergies or a wider
allergy response that involves the sinuses too.
