Human Eye Sensitivity
Human vision is predicated on the eye’s capacity to register visible wavelengths of light. These visible wavelengths range from 400 to 700 nanometers and are perceivable by the cone cells of the eye. In terms of the color spectrum, these wavelengths comprise three primary colors: blue, green, and red, which are then combined and re-combined by the human brain into various shades and distinctions of color. Though color itself is a cognitive construction, its perception is biological. Maintaining the health of the eye is imperative and -- unfortunately -- complicated.
Eye Sensitivity Solutions
Sensitivity to environmental irritants is a common enough phenomenon. Approximately 20 million people in the United States suffer from sensitive eyes while roughly 30 million enjoy wearing contact lenses. Though contact lenses are ideal for people with active lifestyles, they can overly exacerbate sensitive eyes.
Given the varied cocktail of seasonal pollen, mold spores, dust, and second-hand smoke, keeping contacts clean can be a problematic proposition. Regular cleaning and sterile storage containers are both fundamental steps towards reducing irritation. Additionally, selectively using hydrating solutions and re-wetting drops can be very effective counter-measures.
Dry Eyes Sensitivity
There are any numbers of factors that can contribute to what is known as “dry eye” syndrome. Characterized by a persistent, burning sensation, dry eye sensitivity often results from a genetic propensity to generate chemically inefficient or insufficient tears. Either the lachrymal glands fail to make enough tears, or they make ineffective tears. Air conditioning and sensitivity to seasonal allergies can contribute to this condition by forcing air or irritants on the cornea and sclera.
The most effective -- and convenient -- means of alleviating dry eyes is using hydrating drops. These drops have been engineered to mimic the chemical make-up of human tears, with saline being the most active ingredient. Subsequently. The saline works to coat the cornea and sclera and keep tear film in tact.
What can exacerbate dry eye sensitivity are contact lenses. The lenses can irritate the eye by rubbing against the conjunctiva, or the outer layer of the sclera. This constant rubbing can make the eyes red with capillary breaks and make blinking an excruciating inevitability. Seeking a soothing solution, in this case, is all too human. Eye sensitivity is treatable and affordable.
