A contact lens is a lens that attaches directly to the surface of the eye. Abbreviated as C.L- and just Contacts. Contacts are often used to correct vision defects or facial expressions. Those who do not want to wear glasses and want to change the color and appearance of the eyes, use contacts for the beauty of the eyes and to change the non-beauty of the eyes .. !!
Compared to traditional glasses
These are the advantages of contacts.
The distance between the lens of the spectacle and the eye causes a change in focus, which is avoided in contacts.
Traditional spectacles often cause some loss of peripheral vision. This loss does not occur for contacts. As the lens moves with the movement of the eye, the surrounding vision is not lost.
Contact lenses do not have fogging due to heat, cold, rain and wearing of the mask. Sweat is not a problem and can be used comfortably on the playground and does not move while jumping or running.
Contacts do not interfere with wearing cooling glasses and swimming goggles. Makeup is not a barrier or a veil
You do not have to carry heavy loads on your face or ears, which can be like glasses; It does not interfere like glasses during rush hour.
The frame and lens avoid having to be loose and tight from time to time
The color of the pupil of the eye can be changed at will by wearing contact lenses.
No need to think of a frame of glasses that fits the outfit and the occasion. No one knows who the contacts are wearing.
However, the glasses are easy to clean, can be washed with soap and water, and do not cause serious conditions if not cleaned. But you have to touch the eye to clean the contacts. The risk of infection cannot be ruled out. Occasionally there may be a slight bruise or damage to the eye during pulling and pulling. Maintenance of contacts should be rigorous and accurate.
Contacts need to be changed at regular intervals. You have to spend more money on contacts and on a long-term basis than you need for glasses.
Contact should be careful and accurate to ensure that it is suitable for the individual and requires expert examination to ensure that there are no dry eyes, allergies or eye infections. Glasses would be ideal in this situation.
New contact wearers will experience more delays than they need to adapt to spectacle wear. Pulling and placing the contact lens should be done very carefully.
In addition, scientists warn that sleeping while wearing contact lenses can lead to serious eye infections and, possibly, blindness. According to a report published in the Annals of Emergency Medicine, this negligence in wearing contact lenses can lead to retinal infections such as “microbial keratitis”. Not only sleeping with contact lenses, but even fainting may cause eye health problems .. !!
