Presbyopia, commonly known as farsightedness or age-related near vision loss, is the progressive loss of accommodation. This results in difficulty seeing nearby objects clearly. It affects all individuals starting around the age of 40–50. It is usually corrected with reading glasses or with progressive glasses or contact lenses. Presbyopia is caused by the loss of
Dry eye syndrome is a very common eye condition. However, it is not at all trivial. This condition is multifactorial and is characterized by instability of the tear film, inflammation, and damage to the ocular surface. Without treatment, the progression of the disease can result in constant discomfort. These symptoms can interfere with basic daily
