Visual Impairments

Ophthalmic science is the branch of medical science that deals with the study of the eyes and their related diseases, conditions and disorders. One of the most common ophthalmic concerns that people face is visual impairment. Visual impairment can be caused by a number of factors such as genetics, injury, illness or simply due to the aging process. Visual impairments can be classified into two broad categories: low vision and blindness. Low vision refers to the inability to see things clearly or with great detail which can be caused by a variety of factors like age-related macular degeneration, cataracts, glaucoma, diabetic retinopathy and other diseases. Blindness, on the other hand, refers to complete loss of sight in one or both eyes. It is interesting to note that while visual impairments cannot always be cured, many can be treated with corrective measures such as glasses, contact lenses, medication, surgery or rehabilitation. For example, cataract surgery is one of the most common procedures performed for the treatment of visual impairments. In summary, visual impairments are a significant public health concern, with an estimated 253 million people worldwide suffering from some form of visual impairment. As such, ophthalmic science is essential in helping people understand the importance of eye health, and in finding effective treatments and preventative measures to address this problem. By working together, we can help to reduce the impact of visual impairment on individuals and society as a whole.
