In this post, let us understand about Contact Lenses
For individuals with defects in vision, contact lenses are a valuable, virtually imperceptible tool. In a bid to rectify vision troubles like near-sightedness, farsightedness, or astigmatism, thin plastic lenses are placed on top of the cornea of the eye. Contact lenses are separated into two major types: soft and rigid gas permeable.
Soft Contact Lenses For Daily Use
Soft polymer-plastic material amalgamated with a percentage of water constitutes soft lenses. Water permits oxygen to penetrate the contact lens material and enhances comfort. A number of soft contact lenses also make available UV defense. Soft contact lenses give greater comfort in contrast to rigid gas permeable contact lenses when initially placed in the eye.
Several soft contact lenses are not reusable and are discarded after a brief period of use. Being in a position to obtain a fresh pair of soft contact lenses implies less possibility of infection, less cleaning, and greater ease, specially for individuals whose eyes generally manufacture more protein that clouds contact lenses. Other types of soft contact lenses are used on a yearly basis and are commonly not discarded during the period.
While the majority of users prefer soft contact lenses due to their advantages, there are also certain shortcomings. Soft contact lenses without difficulty soak up pollutants like lotion or soap from the hands, which can cause discomfort to the eyes. Soft contact lenses are also more delicate than hard contact lenses and can split or tear with ease.
Types of Soft Lenses Available
Daily Disposables:
Such types of soft contact lenses are used for a day and then discarded. The advantages of these lenses are that it spares the user the trouble of cleaning the contact lenses regularly and diminishes dry eye conditions and discomfort pertaining to contact solutions. They have also a suitable replacement program.
Silicone Extended Wear Disposables:
These soft contact lenses use the latest silicone hydrogel material that can be put on for nearly 30 nights and days. The latest silicone material also checks deposit build up and diminishes dry eye discomfort.
Colored Soft Contact Lenses
They’re trendy and they’re exciting, but colored contact lenses can also be very useful. There are four kinds of colored contact lenses, each presenting a somewhat dissimilar advantage:
Visibility tint: Such types of colored contact lenses are lightly colored so that you can locate the lens if it falls on the ground. Visibility tints don’t influence the color of your eyes.
Enhancement tint: These types of colored contact lenses obtain a translucent shade that’s intended to augment your natural eye color. Enhancement tints are somewhat darker in comparison with a visibility tint.
Color tint: Such lenses have darker, dense shades that alter the color of the eyes. Color shades are available in a diverse range of specialty colors, together with amethyst, violet, and green.
Rigid Gas Permeable Lenses: Rigid gas permeable lenses are more durable than soft contact lenses since they are more rigid in contrast to them.
