As we know that contact lenses are worn right on the corner of the eye, it provides a vision that is more natural. The objects appear in the correct size and position, without any distortion. The distance between the eye and the glasses can vary, causing the objects to appear larger or smaller than they actually are. give you a wider and better peripheral vision than glasses. Contact lenses move along with your eyes and you are always looking through the clearest part of the lens – the optic zone. On the other hand, the frames of the glasses block your peripheral vision, and when you move your eyes to the side, you are no longer looking through the optical centre, causing blurred and distorted vision.
Glasses, at times, do not work, and contact lenses are certainly superior to them. Thick glasses are required in cases of severe short-sightedness, making them very heavy, and your eyes look very small.
Types of contact lenses
- Disposable lenses:
If you do not want to deal with the hassles of regular care and maintenance associated with contact lenses, disposable contact lenses are the way to go. These are used and throw lenses that, depending on the type of lenses, can either be used for just a day or for a week or two before being disposed of for a new one.
- Annual soft contact lenses:
Obviously, as the name suggests, they last for a full year. Oxygen passage through the lens is necessary to prevent drying of the eyes and these lenses, made of soft material, give you just that. Unlike their disposable counterparts, these lenses demand careful and regular cleaning and proper storage. At a stretch, these can be safely worn for as many as 14 hours.
- Flexible and Extended wear contact lenses:
These lenses are so designed so that you can keep them for a long time, without needing to take them off at all. If you despise removing and putting back your contacts every single day, you will love these lenses. You can even sleep with these lenses on.
- Cosmetic lenses:
While the primary function of contact lenses is to correct vision problems, there are also cosmetic lenses that also allow you to alter the colour of your iris. coloured contact lenses come in four different varieties: visibility tints, enhancement tints, opaque colour tints and light-filtering tints. Different contact lenses are designed for different eye types and also depending on their sightedness.
