Blepharitis is a vision condition that affects the eyelids. Eyelids have hair follicles that contain oil glands. Sometimes, these oil glands can get irritated or clogged, leading to eyelid disorders. It is a chronic and uncomfortable condition, but it cannot cause permanent vision loss.
Our vision is a very complex and valuable body function, and there are many different things that can affect our eyes and how well we can see. Most people have heard of eye floaters and flashes, which unsurprisingly, are characterized by visual disturbances. Flashes are spots of light that you see in your field of vision, but that actually come from inside of your eye, while floaters are usually described as being squiggly lines, small, dark dots, rings or cobwebs passing across your vision.
Astigmatism is a very common type of refractive eye error that is characterized by the inability of light to focus evenly on the retina. The retina is the patch of light-sensitive cells found at the back of the eye which is responsible for receiving light and converting it into signals sent to the brain that tell us what we can see and how clearly we can see it. The reason that light isn’t focused properly onto the retina is that patients with astigmatism have eyes shaped more like a football than a soccer ball, causing the light to be focused at more than one place instead. This causes a range of symptoms, including blurred vision, headaches, and eye strain. Fortunately, astigmatism can be treated fairly easily.
Presbyopia is one of the lesser-known refractive eye problems, but eventually, everyone experiences it, even people who are already suffering from either near or farsightedness. However, because people who are farsighted already need vision correction to focus on nearby objects, they may experience presbyopia earlier in life than those who are nearsighted or who have astigmatism.
Research shows that glaucoma is one of the leading causes of blindness in the United States. According to the National Eye Institute, there is still no cure for this debilitating eye condition. To prevent vision loss, eye experts usually recommend their patients start their treatment early. If you have glaucoma, here’s what you should know about managing and treating this disease.
Unsurprisingly, the shape of the cornea of a patient with keratoconus can mean that standard contact lenses don’t fit as well as they should. It should also be noted that contact lenses play an important part in treating keratoconus. One of the most effective types of contact lenses for the condition is known as hybrid lenses.
Also known as keratitis, a corneal ulcer is an open sore that develops on the surface of the cornea – the transparent lens that covers the iris and pupil. Just like any other type of ulcer, they can cause a range of unpleasant symptoms and in some cases, if they aren’t treated, can even lead to permanent vision loss. Fortunately, if your corneal ulcer is detected early it can be treated and it is possible to make a full recovery.
Statistics show that diabetic retinopathy is a leading cause of visual impairment in the United States. Although it’s a serious condition, diabetic retinopathy is treatable and even reversible to a certain degree. Here are the available treatments you should consider for diabetic retinopathy.
