In the recent past, more people have turned into contacts for visual support.

Every year, there is an increase of approximately 4% among wearers of contacts. They have various reasons to replace the traditional glasses. Most of the people introduced to contacts say they do not want to be restricted from an active lifestyle. Others give cosmetic reasons, which lead them to lose the glasses.

The Role of Contacts

Contacts are designed to touch your eye to give it the appropriate magnification. They float on the tear film on the surface of your cornea. They correct refractive errors and help maintain high standards of ocular health. The latest version of contacts are smaller, thinner and less recognizable. They fit perfectly onto your eyes and are comfortable enough.

The role of contacts is a replication of traditional glasses. They function similarly by refracting and focusing light so the objects appear clearly. They are however, advantageous because they can move with your eye as opposed to glasses. This is because they are stuck to the tear fluid on the surface of the eyeball.

Types of Contacts

Not all contacts come with the same features. Like regular glasses, the contacts come in a wide variety of forms to meet different purposes. The design depends on their mode and how regularly you change them. Some people change them as often as on a daily basis while others use them for a month before changing.

Contacts are also defined by their different needs. For example, those meant for astigmatism, nearsightedness, and many other needs of the wearer. To find the contacts that best suit your condition, you need to undergo tests that will determine what you need. You will be relying on the specialists’ recommendation. This means you cannot choose contacts by preference because they have to be functional.

These products also vary in strengths or diopters. Observe the prescription on their box to find out the strength you are exposed to when using them. They are labelled with a plus or minus sign and numbers. These are the definitions of the shape of the lenses and we all know that every shape has a specific role. Each shape is responsible for correcting different vision problems. For example, toric lenses have a weighted bottom and are used for correcting astigmatism. Spherical lenses, on the other hand, are uniform all round and help correct nearsightedness as well as far sightedness alike. Other rare cases include mono-vision, bifocals, and multi-focals. Each problem has a specifically designed lens to address the problem.

Using Contacts

Most users involved in active engagements such as sports always want to know whether it is safe to use them in action. This concern is important because it helps you stay safe by using them correctly. According to experts, contacts give a firm grip on the tear film for a crisp and clear vision. Players can therefore, comfortably use contacts without having to bother about them moving out of place. Your contacts will not be falling out place anytime. You are in no risk of damaging them by falling off like glasses do.

You will not be losing peripheral (side) vision as they move with the eye’s natural movement. Clear vision is important in most sports to avoid high risk of injury. Rapid eye movement involved will not affect the position of the contacts.
