Contact lenses must be the greatest invention in the optical room. The invention was out of need for flexibility and less obstructive therapy for people with sight problems. Lenses were discovered at least a century ago. They were first made of glass and then hard plastic. At the time, it was heavy and crazy expensive.
Today, contact lenses are easy to find and much more affordable. They are also made of soft plastic hence less effect on eye movement. They are much more comfortable than before. People with sensitive eyes and any multiple eye complications can still benefit from the variable options of contact lenses.
If you are not familiar with lenses, they are not complicated as it sounds. Lenses are thin and soft plastic discs fitted around the cornea to help with sight problems from uneven focus to long sightedness and shortsightedness. Contact lenses also help with treating some chronic eye conditions. Some people who had to undergo cataract surgery but did not receive implants can live normally with contact lenses.
Of course, lenses should be prescribed and fitted by a professional eye doctor.
Before you wear contact lenses, it is crucial to engage an eye specialist to help in identifying suitable lenses for your condition. Lenses are medical devices; just like drugs, if you use them inappropriately you risk more damage to your eyes. Besides, the eye is a sensitive part of the body. The fact that lenses are fitted on the cornea, depending on size and curvature of an individual’s eye makes it a delicate process. It is crucial to engage experts for proper fitting.
Contact lenses are also worn for cosmetic purposes; still, you need to consult an eye specialist to check on condition of your eye and advice whether lenses are suitable for you.
Who should wear contact lenses?
Most people get excited with the contact lenses idea. In fact, 9 out of 10 would want to wear lenses whether they have eye complications or merely to change color of their eyes. While there are no strict measures on suitability of lenses, not everyone is advised to wear lenses.
People with the following conditions are unfit for contact lenses.
- If you have problems with eye lubrication
- History of severe allergic infections considering the eye is a sensitive body part
- If you have had repetitive eye infections
- If your job or daily activities expose you to high amount of dirt, smoke, and dust
- People with specific vision problems or need specific lenses
Types of contact lenses
Lenses vary on basis of material, lens intensity, and color among other factors. This is why it is important to schedule examination with an eye specialist to determine your condition and suitable contact lenses.
Soft contact lenses
These lenses are thin and flexible discs. They are subdivided into; extended wear and daily wear. A doctor will advise on either of the lenses depending on severity of your condition. Daily wear lenses are removed and cleaned while extended wear lenses are for 24/7 use, throughout the night. Extended wear lenses are associated with infections if you over use or extend the prescribed period.
Hard contact lenses
Hard contact lenses are for extreme conditions. They are made of hard plastic, which is a little uncomfortable. These lenses can easily slip off the cornea when you engage in rigorous physical activity. While most people opt for soft lenses, it is never a patient’s decision. Severe conditions require hard lenses; they have more clarity and obviously durable.
Most hard contact lenses are for daily wear because they are for specific lens conditions.
The type of contact lenses determine when and how to clean. Both daily and extended wear lenses should be removed and cleaned at specific times as advised by an eye specialist. Typically, sterile tools are provided for effective and easy cleaning. Do not use home-made solutions to clean lenses.
