1. vitamin a protects the cornea, and they help lubricate the eyes and prevent dryness.
2. chalazion: a cyst in the eyelid.
keratitis: inflammation in the cornea.
scleritis: painful inflammation in the sclera.
3. astigmatism: refractive error of the eye that causes blurred vision. They are the most common reason why a person goes to see an eye professional.
4. symptoms result in your eyes turning in or out, innability to judge depth, or poor vision in one of the eyes.
5. symptoms are Cloudy, fuzzy, foggy vision, loss of color intensity, double vision, difficulty seeing at night, problems seeing shapes against a background or the difference between shades of colors.
1. because the retina and tissues behind the eye ARE vitamin A.
2.cataracts, glaucoma, astigmatisms
3. irregular curvature in the lens of an eye
4. eyes that turn in or out
-Eyes that do not appear to work together
-Poor vision in one eye
5. cloudy vision or loss of color intensity
1. Vitamin A forms the visual purple and visual violet of the rods and cones of the retina.
2. Itchy eyes, blurred vision, and puffy eyes
3. A type of refractive error of the eye
4. Eye turns in or out, eyes do not appear to work together
5. Decreased clarity of vision, night vision is diminished
1. Vitamin A makes the visual purple and violet within the rods and cones of the retina.
2. major eye disorders: pink eye, itchy eyes, blurred vision
3. Astigmatism is a refractive error in the lens of the eye. Light fails to come to a single focus on the retina to produce clear vision but instead multiple focus points occur.
4.symtoms of amblyopia- eyes that turn in or out, eyes that do not appear work together, inability to judge depth correctly
5. symtoms of cateracts- blurred vision, difficulty with glare, dulled color vision, increased nearsightedness, occasional double vision in one eye.
1. Vitamin A forms the visual purple and visual violet of the rods and cones of the retina. You might have heard of rhodopsin and iodopsin pigments present in rods and cones, respectively. These are conjugated proteins. For example, rhodopsin is composed of opsin and reteneine.
2. 1. Hordeolum — a bacterial infection of sebaceous glands of eyelashes.
2.Chalazion — a cyst in the eyelid (usually upper eyelid)
3.Blepharitis — inflammation of eyelids and eyelashes; characterized by white flaky skin near the eyelashes
3. Astigmatism is an eye condition with blurred vision as its main symptom. The front surface of the eye (cornea) of a person with astigmatism is not curved properly – the curve is irregular – usually one half is flatter than the other – sometimes one area is steeper than it should be.
1. Forms the visual purple and violet of the rods and cones of the retina.
2. Amblyopia, Astigmatism, and Cateracts
3. A condition in which abnormal curvature of the cornea can cause 2 focal points to fall in 2 different locations making objects up close and at a distance appear blurry.
4. Eyes turning in or out, they work together, inability to judge depth correctly, and poor vision in one eye.
5. Blurred vision, dulled color vison, increased nearsightedness
1. It forms the rhodopsin protein, which helps with the violet light in the rods, allowing you to see better in the dark.
2. Cataracts- a white film develops over the eye causing blindness
Glaucoma – causes damage to the optic nerve because of inflation
Iritis- inflation of iris
3. It is when the lens is irregularly shaped, making contacts uncomfortable
4. Eyes are not in coordination with each other (lazy), vision problems in one eye
5. Terrible vision, eye is clouded by white film
2. Cataracrs, conjunctivitis, and astigmatism.
3. Optical defect that cause blurry vision because the eye can not focus.
4. If eyes don’t turn in our out, don’t seem to work together, or an inability to judge depth.
1. Vitamin A forms the visual purple and visual violet of the rods and cones of the retina.
2. The major eye disorders are astigmatism, cataract, and amblyopia.
3. Astigmatism occurs when the front surface of your eye or the lens inside the eye is slightly irregular in shape.
4. Symptoms of amblyopia is blurred vision, crossed eyes, or misaligned eyes.
5. Symptoms of cataracts are blurred vision, vision loss, or no chance of visual improvement.
1. Vitamin A is good for eyesight because it helps prevent night blindness and prevents cataracts
3. A astigmatism is a defect in the eye or in a lens caused by a deviation from spherical curvature; results in distorted images.
5. Symptoms of cataracts are clouded, blurred or dim vision, increasing difficulty with vision at night, sensitivity to light and glare, frequent changes in eyeglass or contact lens prescription, fading or yellowing of colors, double vision in a single eye
1. Vitamin A is important for the eyesight because vitamin A forms the visual purple and visual violet of the rods and cones of the retina.
2. Eye disorders: chorioretinitis, choroiditis, and retinitis.
3. Astigmatism: A defect in the eye or in a lens caused by a deviation from spherical curvature, which results in distorted images, as light rays are prevented from meeting at a common focus.
4. Symptoms of amblyopia include: An eye that wanders inward or outward, eyes that may not appear to work together, and poor depth perception.
5. Symptoms of cataracts: blurred vision and glare from lights.
1.Vitamin A forms the visual purple and visual violet of the rods and cones of the retina.
2.Glaucoma, cataract, Diabetic Retinopathy,Refractive Errors

5. Some symptoms of cataracts are foggy vision, halos around lights, and double vision in one eye.
1. Vitamin A has retinol which collects in the surface of cells of the retina of the eye. When needed, the cells of the eye can take stored retinol and use it as a building block for rhodopsin.

5. Clouded vision
1) Because Vitamin A forms the visual purple and visual violet of the rods and cones of the retina.
2) glaucoma, cataracts, and night blindness.
3) Blurred vision due to an irregular shape of the eye.
4) Eyes that do not move together in the same direction. Eyes that do not fix on the same point. Crying or complaining when one eye is covered.

1. Vitamin A is good for the eyesight because it protects thee cornea and help keep the eyes moist and not dried out.
2. Chalazion-a cyst in the eye, Hordeolum- a bacterial infection of the sebaceous glands of eyelashes, and Blepharitis- inflammation of eyelids and eyelashes.
3. Astigmatism-a defect in the eye or lens caused by the spherical curvature, resulting in skewed and distorted images.
4. Some symptoms of amblyopia are: poor judgment of depth, poor vision, eyes that turn in or out, and eyes that don’t work well together.
5. Some symptoms of cataracts include: clouded/blurred vision, bad night vision, seeing “halos” around lights, and double vision.
1. Vitamin A helps form parts of the rods and cones responsible for picking up images in the retina.
2. Glaucoma, Cataracts, and Astigmatism are three major eye disorders.
3. Astigmatism is when someones eye is irregularly curved, which messes with vision.
4. Amblyopia, also known as lazy eye, occurs when one eye does not properly link up with the brain and sends images which are ignored in favor of the better eye. Sometimes the weak eye appears to turn out or look a different direction than the better eye.
5. Cateracts can cause dull vision, weak night vision, fading of colors, and sensitivity to light.
