Eye Quizzes Online & Trivia

The palpebral conjunctiva is known to be a part of the conjunctiva. This is a clear membrane and the main goal of this is to coat the inside portion of the eyelids. There is another membrane that coats the outer area of the eye called ocular conjunctiva. There are some people who have issues with their conjunctivas because of a disease called conjunctival concretions. These come in small and yellow-white lesions that may affect different people. This is a disease that is more common for the elderly. If this would be detected early, there are different treatments that are possible in order to prevent this condition from occurring.

This question does not make sense because:1. F is pointing to two parts2. the answer (B) is pointing to the LENS3. F is really the Retina.

When we look at an object, light rays from every part of the object enters into the eyes, the light rays then pass through the cornea, the aqueous humour, lens and vitreous humour, the light rays are bent and image is formed on the retina.the vitreous humour converts the light rays to electrical impulses , before reaching the retina to stimulate the rods and cons to invert the image. the retina views images in an inverted form and not the actual size. the electrical impulses pass through the optic lobe which transmits it to the optic fibre to send impulses to the brain.from the optic fibre the impulses are sent to the vision centre cerebral hemisphere where the image is formed and the real size and colour of the image is seen. images are formed and seen properly when they fall on the fovea centralis. note that images on the retina are smaller but we see the images as the actual size

Lens ! The pupil is the opening in front of the Lens

Constriction of the pupils with near vision-2. convergence of the axes of the eyes-constriction of the pupils with near vision. -to assess the accommodation response, the client looks at a distant point then shifts their gaze to a near object a few inches away. the expected response is convergence of the eyes and constriction of the pupils to adjust for near vision. direct and consensual pupil constriction. -this is an expected finding when assessing the pupillary response to light. parallel movement of the eyes. -the six cardinal fields of gaze assess parallel movement of the eyes. convergence of the axes of the eyes. -the client looks at a distant point then shifts their gaze to a near object a few inches away. the expected response is convergence of the eyes and constriction of the pupils to adjust for near vision. light reflection at the same spot in both eyes. -this is the expected finding with the corneal light reflex.

The eye is a very sensitive part of the body. It can be more vulnerable than the other senses and would need to be taken care of more. It is common that people will sometimes get soap, shampoo, and other chemicals in their eyes. If in case this occurs, they need to flush out the chemicals with water. If the irritation persists, seeing a doctor is necessary. There are still other causes of eye injury though such as getting your eye scratched by your own nails or another object. Even rubbing your own eyes can cause corneal abrasion so you should avoid doing this. Eye swelling is also another possible cause of eye injury. Getting hit by a hard object in the eye such as a fist or other hard objects can definitely cause eye injury.

They are probably most common in people of mixed race, the Middle East, North Africa, and India. Hazel eyes are considered a recessive trait. Hazel, green, and mixed eyes have more easily visible patterns than blue and brown eyes. In "the average white American", the most common eye color is brown, followed by blue, then hazel, and then other mixed eye colors, with green eyes being the rarest of all. Hazel eyes are not the MOST common, but theyre definitely not rare either. For some reason, hazel eyes are most common in people of these regions or with this type of ancestry. One theory is that the groups listed are very mixed-- they have European, African, and Asian roots and so in-between colors like hazel are common because these people carry so many mixed genes, including those for blue, green, brown, etc. eyes whereas people of pure ancestry have a more limited gene pool and are just likely to inherit either brown or blue eyes depending on where they are from. All eye colors are recessive to brown. Hazel and any medium/mixed colors usually have the most patterns, or at least, the most visible patterns. With blue and brown eyes, they are just one solid color, so even if there are multiple layers of brown or blue, you wont be able to see patterns. Hazel, on the other hand, are green, brown, gold, orange, etc. so because each layer is different, you can usually see what each layer is doing (forming a starburst, stripes, spots, flecks, etc.). (Think of it like this: if you color on a blue canvas with just blue paint, you wont really be able to see much in terms of patterns. Yet, if you have a grey canvas and you use brown, green, yellow/gold and orange paint, the patterns you make will be easy to see.) Most white Americans are mixed- They have Southern, Western, Northern European ancestry, maybe some African blood, and maybe some Native American blood, etc. So brown eyes are more common than blue. In most of Europe, however, blue eyes are the most common.

Giraffes are the tallest living animals on the earth, measuring up to 18 feet tall with their neck being around 53% of their height. With their incredible height and long blueish-black tongues, the giraffes are able to feed off of the tallest of trees which supplies them with their nutrition of leaves, flowers, and fruits. Giraffes live in herds that consist of related females and the offspring. Male giraffes establish dominance amongst a herd by fighting using their necks, referred to as “necking”. Many giraffes are found in captivity throughout the world but are native to many different parts of Africa.

When kittens are born, they are born with their eyes and ears sealed shut, only able to use their noses to search for their mother and their siblings born in their litter. As kittens grow older, their ears open, followed by their eyes. When they kittens eyes finally open around day seven to ten, they are blue but will change to their life-long eye color shortly after. Kittens are highly dependent upon their mother for the first few weeks, needing their mother to help them stay warm, be fed, and as protection against infectious disease. Once the kittens reach between six to eight weeks, the kittens are much more independent.

To avoid any contraindications to the eye such as swelling ,watery and sensitive eyes

Students need to be studying textbooks, and often academic articles that are typically in tiny print. This can cause eyestrain and worse, especially if the lighting is insufficient. This may well be the case in many student digs. However, it is more likely that students are staying up late with their eyes on mobile phones, again with tiny detail. the use of TV, ipads and mobile phones has adverse effect upon sleep, and lack of sleep is a key factor in impaired health generally.
