correcting refractive errors
Contact Lenses are small medical devices worn on the corneal lens of the eye for bifocals, distance vision, and astigmatism correction. As with glasses, contact lenses perform this primary function by adding or removing focusing power from the eye’s lens and corneal tissue and thus correcting refractive errors. However, unlike glasses or contact lenses, wearing contact lenses has a number of disadvantages.
One of the major disadvantages of contact lenses is the fact that they cannot be worn for extended periods of time due to their significant weight. Wearing them for a period of time increases the risk of pressure build-up between the corneal surface and the lens, which can cause irritation, discomfort, infections, and even damage of the eyes. Because these types of contacts are placed directly onto the corneal surface, they present the same hazards as any other contact lens, including increased risks of abrasion, wear and tear, and the development of complications such as dry eye syndrome, deposits of moisture on the lens, allergic reactions, and inflammation. Wearing these lenses requires frequent cleaning and is extremely time-consuming. Wearing them for longer periods of time can also increase the risk of developing dry eye syndrome. Therefore, if you wear contact lenses for any length of time, you should consult with your eye doctor for a recommended cleaning schedule.
cause blurry vision
Another major disadvantage of these lenses is that many people suffer from astigmatism, which can greatly affect their vision. In fact, one of the most common vision impairments that sufferers of astigmatism may experience is a reduction in peripheral vision. Because astigmatism may cause blurry vision in either the farsighted or nearsighted state, contact lenses may provide some relief to this condition, but their effects are usually temporary. Also, because astigmatism may cause corneal scarring, wearing these lenses results in the formation of additional corneal tissue, which increases the likelihood of further vision distortions or issues. Therefore, astigmatism may recur even after treatment with corrective lenses.
The best alternative for those who do not have astigmatism or those who do not wish to expose their eye to possible dangers is progressive multifocal contact lenses. These lenses improve both the farsighted and nearsighted conditions, which results in a clearer and more comfortable vision. When compared to bifocals or trifocals, which correct only one eye, these products work by combining the correction of two separate vision problems. In addition, because these products correct both near and far blurriness, there is significantly less strain on the eyes. This makes it easier for patients to read printed materials or perform basic tasks, such as reading the small print on a computer screen. Because these products require less handling and are much easier to store, they are also a more convenient choice than bifocals and trifocals.
contacts over glasses
A patient who prefers contacts over glasses will be pleased to know that they can now use multifocal contact lenses. While glasses can be a great fashion statement and improve an individual’s appearance, wearing glasses can be very cumbersome, limiting the individual’s freedom of movement and increasing the risk of eye injury. Additionally, glasses can present a certain level of self-consciousness, as they cannot be used for certain tasks, such as operating machinery or playing sports. Wearing contacts instead eliminates these restrictions, providing freedom of movement and a more comfortable and natural wearing experience. Furthermore, progressive contact lenses are available in a wide range of colors and styles, allowing people to express their personal preferences.
When deciding between wearing glasses and contact lenses, patients should be aware of the different factors that affect their effectiveness. Glasses are generally recommended for people who are between fifteen and twenty years of age, while contact lenses are ideal for people who are elderly or those who cannot wear glasses. Before deciding on the best option for you, it is important to consult an eye doctor, who can advise you on the best course of treatment.
