All of us are not fortunate enough to enjoy perfect eye health. Usually, people suffer from vision-related disorders, eye disorders caused by medical conditions such as diabetes, or age-related eye disorders. You may feel that nothing is wrong with your eyes, but you must understand that many serious eye disorders have no symptoms. Regular eye checkups, therefore, are a must.

Here is a list of some common eye conditions:

• Vision-related eye disorders such as hyperopia, myopia, astigmatism, and presbyopia
• Age-related macular degeneration (AMD)
• Cataracts
• Diabetic Retinopathy (DR)
• Glaucoma
• Ambyopia or lazy eye
• Strabismus
• Floaters and flashes
• Retinal Detachment

Age-related Macular Degeneration (AMD)

AMD, also known as macular degeneration, usually affects middle-aged and aged people. There are two AMD types—dry AMD, which is the milder variety, and wet AMD, which is the more severe variety. Treatment is easy if the condition is detected in the dry AMD phase. In case of wet AMD, several weak blood vessels are formed in the retina, leading to bleeding, scarring, and discharge of fluid from the eye. Read more on Age-related Macular Degeneration

Cataracts

Cataract is the condition in which the lens becomes opaque and cloudy, making it very difficult for the patient to see. Cataracts are caused by a wide range of factors such as age, injury, inflammation, exposures to harmful rays, surgical procedures, genetic disorders, skin disorders, and others. The condition can be corrected by wearing glasses or by surgical procedures. Read more on Cataracts

Corneal Graft

A corneal graft is a surgical procedure used by eye surgeons to correct corneal defects that cannot be treated with medication, eye drops, contact lenses, and glasses. Read more on Corneal Graft

Floaters and Flashes

Floaters are the tiny specks, dots, or strands one sees floating in one’s field of vision. Caused by formation of collagen strands, specks, or dots in the vitreous, floaters are harmless and do not cause vision loss. However, if one sees too many floaters or if the floaters are accompanied by brilliant flashes of light, one must fix an appointment with the ophthalmologist. Read more on Floaters

Diabetic Retinopathy

As its name suggests, diabetic retinopathy is a condition that mainly affects diabetics. The retinal blood vessels are damaged, resulting in bleeding, scarring, and rupture of the retina. If left untreated, it could lead to retinal detachment and irreversible loss of vision. Read more on Diabetic Retinopathy

Glaucoma

Glaucoma is a condition in which the optic nerve is damaged because of increase in intraocular pressure, leading to loss of vision. Glaucoma does not cause complete blindness as a rule. In fact, if detected in its early stages, it can be treated with medication and eye drops and damage to the nerve can be curbed. Read more on Glaucoma

Retinal Detachment

In case of retinal detachment, a serious eye disorder, the retina peels off the wall of the eye, making it difficult for the patient to see. When detached from the wall of the eye, the retina is unable to function properly and send the correct electrical impulses to the brain. If you are diagnosed with retinal detachment, your doctor might suggest a surgical procedure to correct the condition. Read more on Retinal Detachment

Eye Health Page

Your eyes are responsible for filling color in your life, owing to which they deserve a lot of care and attention. The human eye is a delicate and sensitive organ, susceptible to a number of vision-related and age-related disorders. Since some of the most serious of these disorders hardly have any symptoms, you must schedule eye checkups as regularly as possible so that your eye doctor detect signs of eye disorders if any and start treatment at the earliest possible.

On this page, you will find almost everything you need to know about eye health. However, you must understand that the information on this page is not a substitute for consultation with a certified ophthalmologist. If you suspect that you have a problem in one or both your eyes, you must talk to your ophthalmologist and get your eyes examined at the earliest possible. Read more on Eye Health

Eye Anatomy – How We See

Understanding the anatomy of the eye is essential to understanding the process of seeing. Those parts of the eye closely associated with the seeing process are the cornea, the pupil, the iris, and the retina.
When you focus on an object, rays of light from that object enter your eye through the pupil, which is the opening at the centre of iris. The pupil, the iris, and the cornea then direct these rays toward the lens, a crystal clear part of the eye, which in turn directs those rays to the retina, a photosensitive tissue comprising cones and rods at the back of your eye.

A chemical reaction now takes place inside the retina, which transforms into an electrical impulse that is sent to the brain via the optic nerve. The brain then makes sense of the message, as a result of which we see.
