Contact lens technology has not progressed to the point of creating the perfect contact lens for every person. Contact lenses do not give all users perfect vision. However, there are a wide range of contact lenses available, as well as many advantages to wearing contact lenses.

Contacts Are Available for More Eye Types

Individuals with special vision needs were not able to wear contact lenses just a few years ago. Now, contact lenses are available for just about every eye type. Individuals with astigmatisms, dry eyes, and even people who have had cataract surgery can now wear contacts. Contact lenses are even available as bifocals. New technology allows contacts to be made from a range of material to match the wearing habits and eye conditions of the patient.

The Benefits of Gas Permeable Contact Lenses

Individuals with astigmatisms may be prescribed gas permeable contact lenses. These contacts are made from a semi-rigid, silicone-based plastic, which lets oxygen penetrate the lens and come into contact with the cornea. Because of how rigid the lenses are, it can take a few weeks for a person to get comfortable wearing gas permeable contact lenses.

Using Soft Contact Lenses

Soft lenses, or disposable contacts, are similar to a wet sponge. They are made of between 38 and 70 percent water. The benefit of soft contact lenses is that they are oxygen permeable. The cornea needs oxygen from the environment in order to stay healthy and remain transparent. Because of their malleable quality, soft contact lenses are easier to adjust to, and wearers are usually comfortable with them in their eyes after just a few days.

The Advantages and Disadvantages of Contacts

Contact lenses are cosmetically preferable for most people because they allow them to see clearly without altering their appearance. Those with strong prescriptions prefer contact lenses because they have improved peripheral vision and minimized visual distortion. Glasses are a nuisance for active people because they can easily be knocked off, become steamed over, or break.

Contact users must wear their contacts responsibly. Sleeping with contact lenses can lead to eye infections as well as corneal ulcers that can damage a person’s vision. Additionally, there are some people who have a prescription or an eye shape that just makes wearing contacts impossible. For them, purchasing glasses from an optometrist or using their prescription to buy glasses at places is the only option that works for them.

At the end of the day, both prescription eyeglasses and contacts serve the same purpose. Their goal is to help a person see clearly and better interact with the world around them.
