There have been many advances in the contact lens industry over the past years and some people may want to re-consider contacts at this time. With today’s contacts technology, a vast majority of eyes can be corrected by contact lenses and the prescription range of contacts has significantly expanded. Contact lenses using automatically techniques can correct high amounts of astigmatism. Bifocal contact lenses are available in more styles now.
Contact lenses fit right against the eyes so that peripheral vision can be improved. Different people have varying eye anatomy and tear chemistry so that a specific person requires certain lens brand and type. In choosing proper lenses, a patient should tell the doctor his occupational and recreational needs, in order to get an individualized pair of lenses.
One’s lifestyle plays an important role in deciding lens type. For instance, individuals performing computer tasks all day long may suffer intermittent blurring and discomfort. In this case, lenses made of dehydrating materials are more suitable. Soft lenses with plasma treatments on the surface can also help maintain the eyes moist.
Bifocal lens are also rapidly advancing in these years. Most soft lenses are simultaneous designs, which have a central zone for distance vision and a surrounding zone for near vision, or vice versa. Another common modified version is that the dominant eye is fit with a distance center lens and the other eye with a near center lens.
Patients with astigmatism are always referred to having a football-shaped eye. Soft contact lenses aligned in the correct orientation with the eye prescription can be used to correct astigmatism. When these lenses unfortunately rotate off alignment, blurry vision may occur for short periods. Patients with high amounts of astigmatism may even suffer more fluctuation.
In the past, some people were dissuaded from contact lenses because of their occupations. However, there are huge breakthroughs in the lens material technology during the past few years. The addition of silicone and plasma treatments allows more people to take contacts now. In addition, daily disposable contact lenses have changed the situation that children were not allowed to wear contacts because they could not take adequate hygiene and lens care.
Some people could not adapt to contact lenses in the past. Fortunately, modern lenses are always designed with enhanced comfort and eye health and cause less irritation. Daily disposable contacts are particularly safe that they are never reused. What’s more, some of the extended wear lenses can last 30 days continuously, while ensuring comfort.
