The opposite condition to myopia is Hyperopia (farsightedness). Instead of an ability to see near objects better than far, the hyperopic eye sees far objects better than near. The hyperopic eye is a shortened oval, as compared to a normal eye. This shortness causes light to focus behind the retina, causing the perception of a blurred image.

The distortion of light as it passes through the cornea is known as Astigmatism. The astigmatic eye has a cornea which is not perfectly smooth and spherical, with equal curvature on all sides. Because the astigmatic eye is not round, but shaped more like a football, there is a distortion or tilting of images due to asymmetric bending …
Myopia is the medical term for ”nearsightedness”, a condition in which the eyes can see close objects but not distant objects. It is usually an inherited trait and is oftentimes found in children between the ages of 8 and 12. Myopia increases as children grow, leveling off in adulthood. Myopia less commonly manifests itself in adulthood. It is …
What causes it?
Caused for dry eyes is a lack of tear production. Tears normally keep the eyes moistened and lubricated. However, stinging, burning, dryness, and redness will result if enough tears are not produced to keep the eyes wet and comfortable. While discomfort is the primary result of the condition, infection and corneal scarring may occur …
A person with ptosis cannot lift one or both of their eyelids all the way, usually because of a malformed eyelid-lifting muscle. The affected eyelid may droop only slightly, or it may droop enough to partially or completely cover the pupil, restricting or obscuring vision. Ptosis may be inherited, be present at birth, or occur later in life. …
They are also called Muscae volitantes (from the Latin, meaning “flying flies”), or mouches volantes (from the French). They may appear as spots, threads, which float slowly before the observer’s eyes. The common type of floater, which is present in most people’s eyes, is due to degenerative changes of the vitreous humour. The perception of floaters is known …

It requires an urgent referral and thorough examination by an ophthalmologist or optometrist along with urgent treatment to control the inflammation

It is the medical term for poor visual development, usually in one eye and usually occurring in the early stages of life. In most cases, it is caused by lack of use of one eye when the brain ”favors” one eye over the other. Amblyopia is essentially a disorder of the brain cells that control the vision in …
Typically, the eyes work as a team, aiming at the same spot, providing the brain with the information it needs to create a three dimensional image. This three dimensional image provides a person with depth perception. Strabismus also known as heterotropia, is a condition in which the eyes are not properly aligned with each other. It typically involves …
The macula is the most central portion of the retina, directly opposite the lens. It is where the greatest number of light sensitive cells, called cones, are located. Cones are the cells which allow us to see color and fine detail. The high concentration of cones in the macula gives people extremely detailed and rich central vision.
