Contact Lens FAQs Q1:Will wearing contact lenses hurt my cornea?A: Contact lenses themselves are not harmful, but improper wearing techniques, poor care methods, and extended wear time can lead to eye infections and inflammation, which may indirectly harm the cornea. Always use contact lenses as directed and develop good care habits. Q2:Who is not suitable for wearing contact lenses?A: It’s essential to have a comprehensive eye examination before trying contact lenses for the first time. Follow your doctor's recommendations. Individuals with eye conditions like blepharitis, conjunctivitis, keratitis, severe trachoma, dry eye, or glaucoma should avoid contact lenses until inflammation subsides.Additionally, it’s best to refrain from wearing lenses during menstruation, pregnancy, or when experiencing a cold due to unstable intraocular pressure. Avoid wearing lenses while swimming or bathing to reduce the risk of infection. Q3:Why is the prescription for contact lenses different from that of glasses?A: Glasses sit approximately 12mm from the eye, which creates a vertex distance effect. In contrast, contact lenses are placed directly on the cornea, making their prescription slightly lower than that of glasses. Q4:I have astigmatism; how do I choose the right prescription?A: If your astigmatism is 150 degrees or more, or if the ratio of myopia to astigmatism is 4 or less, you need specialized toric contact lenses. For astigmatism under 150 diopters and a higher myopia ratio, regular contact lenses will suffice. Always consult your eye care professional to determine the appropriate prescription. Q5:What should I do if I feel a foreign body sensation after wearing contact lenses?A: A foreign body sensation may indicate that the lenses are damaged or worn incorrectly. Remove the lenses and check for any damage or the correct orientation.If discomfort persists, seek medical assistance. Some discomfort is normal for first-time users and should improve with time, but ensure there are no issues with the lenses. Q6:Does a larger diameter contact lens provide a better magnifying effect?A: While a larger diameter can enhance the magnifying effect, it also covers more of the cornea, potentially reducing oxygen supply to the eye. Colored lenses have an additional pigment layer, which further decreases oxygen permeability. For eye health, avoid excessively large diameters, especially for prolonged wear. Q7:My eyes are very dry, and I use eye drops whenever I wear contact lenses. Is this okay?A: While it’s fine to use eye drops for relief, avoid over-reliance, as this can diminish your natural tear production over time. If dryness persists, consider an eye exam to rule out underlying conditions and choose low-water-content lenses for better compatibility. Q8:Is a higher water content in lenses better for comfort?A: While higher water content can enhance comfort for hydrogel lenses due to their oxygen permeability, this principle does not apply to silicone hydrogel lenses. High-water-content hydrogel lenses may absorb tears and lead to dryness as moisture evaporates. Therefore, focus on your specific needs rather than solely pursuing high water content.
