Eye diseases

Most people have eye problems at one time or another. Some are minor and will go away on their own, or are easy to treat at home. Others need a specialist’s care. The eyes are complex organs. There are many parts that must work together to produce clear vision. Read on to get a basic overview of eye anatomy and learn about common eye conditions.

Eye Diseases

1. Eye Strain

If your eyes feel strained, give them some time off. If they’re still weary after a few days, check with your doctor to make sure it isn’t another problem. Anyone who reads for hours, works at a computer, or drives long distances knows about this one.

2. Red Eyes
Their surface is covered in blood vessels that expand when they’re irritated or infected. That gives your eyes the red look. Red eyes could be a symptom of another eye condition, like conjunctivitis or sun damage from not wearing shades over the years. It can cause redness, itching, burning, tearing, discharge, or a feeling that something is in your eye.

3. Cataracts
A cataract is a clouding of the lens, causing blurry or color-tinted vision. People with cataracts often report “haloes” surrounding objects they’re looking at, particularly at night. often form slowly. They don’t cause symptoms like pain, redness, or tearing in the eye.Some stay small and don’t affect your sight. If they do progress and affect your vision, surgery almost always works to bring it back.
This condition is most common in older adults. A healthy lens is clear like a camera’s. Light passes through it to your retina — the back of your eye where images are processed.

4. Night blindness
Some people are born with this problem, or it might develop from a degenerative disease involving the retina, and that usually can’t be treated…a lack of vitamin A all cause a type of night blindness that doctors can fix. Is it hard to see at night, especially while driving? Is it tough to find your way around in dark places, such as movie theaters?

5. Glaucoma
Glaucoma is increased pressure of the fluid inside the eye. This can cause optic nerve damage. Glaucoma is a common cause of blindness. Age, race, and family history are important risk factors. Your eye is like a tire: Some pressure inside it is normal and safe. But levels that are too high can damage your optic nerve. Most people who have it don’t have early symptoms or pain.

6. Lazy Eyes
Lazy eye or amblyopia happens when one eye doesn’t develop properly. It’s found in infants, children, and adults, and rarely affects both eyes. Lifelong vision problems can be avoided if a lazy eye is detected and treated during early childhood. Treatment includes corrective glasses or contact lenses and using a patch or other strategies to make a child use the lazy eye. One eye may be inhibited by problems such as a lid droop, tumor, or misaligned eyes that are not corrected when a child is young.

7. Age related Macular degeneration (AMD)
AMD causes blurry vision, especially in the center of the field of view. According to the Centers for Disease Control and Prevention, Age-related macular degeneration (AMD) is gradual damage to the cells of the macula. This condition is most common in people over 60 years of age.

8.Color blindness
When you can’t see certain colors or can’t tell the difference between them (usually reds and greens), you may be colorblind. Most people who have it are born with it, but you can get it later in life from certain drugs and diseases. It happens when the color cells in your eye (the doctor will call them cone cells) are absent or don’t work.

This is the name for a group of diseases that cause inflammation of the uvea. That’s the middle layer of the eye that contains most of the blood vessels. These diseases can destroy eye tissue, and even cause eye loss. People with immune system conditions like AIDS, rheumatoid arthritis, or ulcerative colitis may be more likely to have uveitis.

10. Retinal detachment
When the retina separates from the back of the eye, it’s called a detached retina. It causes blurry vision and partial or complete loss of vision and should be treated as a medical emergency. The retina is a thin lining on the back of your eye that is made up of cells that collect images and pass them on to your brain. Retinal disorders block this transfer. Retinal detachment happens when the retina separates from the layer underneath.

11. Dry eye
Dry eye is a lack of tears. It’s usually due to a problem with the tear formation, tear ducts, or eyelids, or it’s a side effect of certain medications. This condition can cause pain and blurry vision. This happens when your eyes can’t make enough good-quality tears. You might feel like something is in your eye or like it’s burning.

12. Vision changes
Some vision changes can be dangerous and need immediate medical care. Anytime you have a sudden loss of vision or everything looks blurry — even if it’s temporary — see a doctor right away. Eye diseases likemacular degeneration, glaucoma, and cataracts, can cause vision problems.

Floaters are usually normal, but they sometimes can be a sign of a more serious eye problem, like retinal detachment. That’s when the retina at the back of your eye separates from the layer underneath.

14. Eyelid Problems
Pain, itching, tearing, and sensitivity to light are common symptoms of eyelid problems. You might also have blinking spasms or inflamed outer edges near your eyelashes.
