![]() ![]() Tears will last longer, and accordingly, the tear osmolality will decrease. VISTA® Tears contains a unique and balanced mixture of Polyethylene Glycol combined with Propylene Glycol and Hydroxypropyl Guar to perform the dual action of attracting moisture to the eye and locking it in. Tears are vital to ocular health since they protect eyes from harmful microbial invaders (e.g., bacteria, viruses, fungi), debris, and mechanical friction that causes inflammation and discomfort. Most drops are simply a lackluster substitute for the real deal.ĭesigned by leading eye specialists, VISTA® Tears was scientifically developed to perform the lubricating function as natural tears. Bear in mind, however, that tears are an incredibly sophisticated substance. Eye drops are a simple solution that can be used to help lubricate irritated and tired eyes directly. Consequently, dry eye should not be ignored and should be treated properly.Ĭombating the vicious cycle of dry eye syndrome requires advanced treatment. This uncomfortable, gritty sensation results in even more blinking, which perpetuates the nasty loop, and consequently, causes cell death. The friction can cause scratches on the eye especially when the debris is present. This is analogous to running your windshield wipers without fluid. Without adequate lubrication, the likelihood of mechanical damage to the ocular surface increases significantly. When this occurs, the ocular surface is exposed, and a cascade of inflammatory events (e.g., the release of pro-inflammatory factors and cytokines) is kickstarted. ![]() When too few tears are produced-or when the tears lack an oily layer and evaporate quickly-the eye enters a state of hyperosmolarity. Eyes require the unique concoction of compounds found in tears to stay hydrated and healthy. Just because dry eye is a widespread condition does not mean it is normal. It is more common among older individuals, people taking certain medications, individuals wearing contact lenses, or those who have undergone eye surgery (e.g., Lasik, glaucoma, or cataracts surgery). This leaves even well-rested individuals with eyes that feel tired and dry in the morning.ĭry eye can be the result of eating an unbalanced diet (with too few carotenoids and fatty acids) and exposure to dry or polluted air. Most people are sleep deprived to some degree, and in addition, roughly 10% of people sleep with their eyes partially open! This condition, known as nocturnal lagophthalmos, exposes eyes to desiccating air overnight. Relatedly, poor sleeping habits-which is often a consequence of long work hours and exposure to blue light-can intensify dry eye. This can lead to dryness and eye strain since fixating on screens causes our blink rate to drop dramatically-from approximately 20 per minute down to 4! Whether it is for work or leisure, many people spend long hours looking at blue light-emitting electronic screens (e.g., computers, smartphones, tablets, etc). If left untreated, the condition can worsen over time resulting in severe inflammation and physical damage to the eye's surface.ĭry eye disease is exacerbated by the demands and conveniences of modern life. Both issues can occur in isolation or simultaneously. Some people produce too few tears, while others produce poor-quality tears that lack the lipids essential for stabilizing the tear film. With every blink, healing tears remove cellular waste and coat the ocular surface protecting delicate eyes from infection and debris. The oily component of tears slows the evaporation of tears and distributes tears evenly across the eye. Tears-far from being just drops of water-are a highly complex mixture of an aqueous solution, phospholipids (oils), and mucus. Ultimately dry eye is caused by problems associated with tear production. Various factors can leave our eyes feeling left high and dry-some issues are inherent to the individual while others are due to outside influences. Consequently, dry eyes are often unhealthy eyes. This is problematic since our sensitive eyes rely on tears for adequate moisture, nourishment, and defensive support against microbial invaders (e.g., bacteria, viruses, fungi) and debris. Not everyone seeks help for their dry eye symptoms, thus the actual number of people suffering from DED is likely higher. For an estimated 16 million Americans1, their condition is persistent and is classified as dry eye disease (DED). ![]() Roughly 30 to 50% of people experiencing the symptoms of dry eye at some point. If you have or are currently experiencing dry eye, then you are certainly not alone. Dry eye can not only completely undermine your productivity at work, it can reduce your ability to recharge while relaxing. When your eyes feel inflamed, itchy, and tired, getting through the day can seem nearly impossible. Little compares to the discomfort and irritation associated with dry eyes. ![]()
