Nearsightedness, also known as Myopia.
Myopia is a condition where distant objects appear blurry. The myopic eye is slightly longer than normal and is corrected with minus powered lenses.
Uncorrected myopia is the leading cause of distance vision impairment globally.
It's on trend: there is growing interest in contact lenses that correct vision and also enhance the beauty of our eyes. Beauty lenses are medical devices and eyes are sensitive- making it essential to have an eye exam and proper fitting by an eye care professional.
There are two kinds of farsightedness: Presbyopia and Hyperopia.
Presbyopia is an age-related, decreased ability to see nearby objects, especially in low light. Everyone will become presbyopic, usually starting around the age of 40.
Hyperopia affects people of all ages and is where near and occasionally distant objects appear blurry. The hyperopic eye is slightly shorter than normal and is corrected with plus powered lenses.
Astigmatism is a variation in the curvature of the cornea - the clear, round dome covering the eye's iris and pupil - or in the shape of the eye's lens. Astigmatism results in blurred or distorted vision at all distances, varying with the amount of astigmatism.
Glaucoma usually happens when fluid builds up in the front part of the eye, causing increased pressure within the eye which can damage the optic nerve.
Tears help maintain the health of the front surface of the eye and help to maintain clear vision. Dry eye is a condition in which a person doesn't have enough quality tears to lubricate and nourish the eye.
Dry eye is a common and often chronic problem, particularly in older adults.
A clouding of the normally clear lens of the eye.
