Q: Can people with astigmatism wear contact lenses?
A: Yes, there are many contact lens brands that offer toric lenses, which can correct both nearsightedness and astigmatism. Some brands can even correct astigmatism up to -2.75. At Tawaen, we have a special vision exam for people with astigmatism to ensure that they can see clearly and brightly with contact lenses.
Q: Can I just soak my contact lenses without rubbing them?
A: No, it is recommended to rub your contact lenses with cleaning solution for 10-15 seconds before soaking them. Even if the bottle of contact lens solution says "No rub," rubbing your contact lenses gently will help remove protein deposits from the surface of the lenses. After rubbing, soak your contact lenses in cleaning solution again to ensure that they are clean and free of infection.
Q: How do I add or decrease my prescription when wearing contact lenses?
A: Lowering your prescription when wearing contact lenses can make your vision more comfortable. You should reduce your prescription by 0.50 steps if your prescription is higher than -4.00. For example, if your glasses prescription is -6.00, you should reduce your prescription to -5.50 when wearing contact lenses.
Q: Can I sleep with my contact lenses on?
A: No, you should never sleep with your contact lenses on. Sleeping with your contact lenses on can deprive your eyes of oxygen and moisture, which can weaken your immune system and make your eyes more susceptible to infection. It can also increase the risk of corneal abrasions when you take your contact lenses off.
Q: Will wearing glasses and contact lenses alternately affect my vision?
A: No, it will not affect your vision and it can actually be good for your eye health. If you wear contact lenses for more than 12 hours a day, you may experience eye fatigue and dryness. When you get home, you should remove your contact lenses and switch to glasses. This will give your eyes, especially your corneas, a chance to relax, recover, and get enough oxygen.
