Top 8 Super Useful Tips For Colored Contacts Absolutely
1. What Precisely Are Colored Contact Lenses?
Colored contact lenses are similar to clear contact lenses, but they are thicker and have more patterns (regular contact lenses have a sandwich structure with clear sequins in the front and back and a patterned layer in the middle). Contact lenses lack this feature. Superior colored contact lenses do not have a sandwich structure, but rather a first transparent layer and a second pattern layer. (The pattern layer comes into direct contact with the eye and causes irritation.) The following items are referred to as contact lenses. These contact lenses, also known as corneal contact lenses, are a type of lens that is worn over the cornea of the eye to correct or protect it. There are two types of contact lenses: hard contact lenses and soft contact lenses.
2. The Distinction Between Rigid And Soft Contact Lenses
RGP have better oxygen permeability, are less likely to cause hypoxia and dry eye, are easy to maintain, and have a long service life; people with higher requirements for prescription control or eye health can choose RGP, but the disadvantage is that they are not comfortable enough and are not suitable for everyone. Because of the high level of professionalism required for the fitting process, RGPs can only be made in hospitals.
Soft contact lenses have the advantages of softness, itch relief, comfort, and no foreign body sensation. The drawbacks are easy adsorption and sedimentation, as well as a short life span. They are also known as regular contact lenses, which are available in major optical stores.
3. Is It Possible For Anyone To Wear Contact Lenses?
Contact lenses are not appropriate for everyone. How can I tell if they are a good fit for me? The simplest and safest option is to go to a hospital for an examination. Aside from that, in a broad sense.
Contact lenses are used by people who have refractive errors such as myopia, hyperopia, or astigmatism.
People who do not have any other eye conditions (aside from refractive error).
4.People Who Should Not Wear Contact Lenses
- (a) Chronic eye diseases such as keratitis and dry eye, among others.
- (b) Systemic diseases such as type 2 diabetes, chronic sinusitis, rheumatoid arthritis, and so on.
- (c) poor personal hygiene and excessive smoking
- (d) Individuals who are allergic to the nursing solution's ingredients.
- (e) People who have a lot of dust in their home or workplace.
5. How Do I Select Contact Lenses?
- (1) First, examine yourself and consult with your eye doctor to determine your suitability for wearing.
- (2) Select the degree. People who are more than 400 degrees nearsighted will typically wear contact lenses that are 25-50 degrees less than the frame, whereas people who are farsighted will do the opposite.
- (3) Consider the water content; the higher the water content, the easier it is to evaporate and wear for an extended period of time without causing dry and itchy eyes. However, the higher the water content of the lens, the higher the oxygen permeability. If your eyes are prone to dryness, it is best to select ones with a lower water content.
- (4) Examine the base arc. The curvature of the corneal surface is represented by the base arc. One of the influencing factors is whether it is comfortable to wear. You should talk to your doctor about your specific base arc. If there is frequent slippage during wear, there are two possibilities: the base arc is not appropriate or the contact lens quality is poor.
6. How To Care For Your Contact Lenses
- (1) Clean and care for your lenses every time you remove them, regardless of how long you have been wearing them
- (2) Care once a day with a full-function care solution
- (3) Clean with protease tablets every week, which can remove about 70% of the deposits but not completely, so you can't use them all the time
7. Wrong Contact Lenses Can Cause A Lot Of Harm
- Corneal hypoxia: Wearing lenses with low oxygen permeability for an extended period of time can cause corneal hypoxia and damage to the corneal epithelium, which can impair vision.
- An allergic reaction occurs. Metabolites from the eyes are deposited on contact lenses during the wearing process. This causes red eye drops, itchy eyes, and eye pain, at which point you should discontinue use.
- Corneal injury or infection When worn incorrectly, they can cause corneal epithelium damage, resulting in discomfort, foreign body sensation, photophobia, tearing, and, in severe cases, keratitis.
- Eyes that are dry. Wearing soft contact lenses for an extended period of time, particularly lenses with a high water content, causes dry eyes, manifested as foreign body sensation, dryness, burning sensation, blurred vision, increased secretions, and so on.
8. How To Wear Scientifically, You Need To Develop 6 Good Habits
- Always wash your hands thoroughly before touching the lenses, using clean water and soap, and wait until your hands are completely dry before removing the lenses.
- Pay attention to the shelf life of the care solution and carefully read the instructions on the care solution's package, including how long the shelf life is and how long it can be used after opening (usually 3-6 months). Mark the opening date on the bottle when you open it. If it hasn't been used within the shelf life, throw it away.
- To lubricate your eyes, use eye drops. When your eyes are dry and your glasses aren't fitting properly, use some preservative-free or suitable for the wearer eye drops. Use only under the supervision of a medical professional and strictly control the dosage.
- To avoid contamination from other things, keep the contact lens case clean and store it in a cool, ventilated location.
- Before going to bed, always remove your contact lenses. If you do not remove your contact lenses before going to bed, your cornea will be stimulated for a long time and will be in a state of oxygen deprivation for a long time, increasing the risk of infection and causing dry eyes. It can even lead to corneal ulcers. This disease has the potential to cause blindness. It is preferable, strictly speaking, to record the napping time.
- Please check your eyes before putting on contact lenses. It is recommended that you perform a self-examination before wearing contact lenses. If your eyes appear strange (red, itchy, etc.) or you feel uncomfortable, take them off for a while.
Although contact lenses have a shelf life, please do not rely on it. For example, do not use them 24 hours a day, seven days a week, or every day for 30 days in a row. They are undetectable. Protein deposits on your glasses are not completely removed when you clean them, which has an impact on their normal life and cleanliness.
Finally, while wearing contact lenses is not impossible, please do so correctly so that beauty and health can coexist.
