Living Vitamin Review: Treatment Tuesday

Can You Use Rubbing Alcohol To Clean Glasses

The stimulus effect of alcohol will damage the coating of the lens. If the coating of the lens is destroyed, the transmittance of the lens will decrease and the clarity of the lens will decrease. In addition, if the film layer of the lens is damaged, the scratch resistance and anti-reflective properties of the lens will decrease. Especially if the film layer of the lens is damaged severely, the lens is easily scratched, which directly affects the vision. Therefore, when cleaning the lens, you must be careful not to use irritating cleaning.

Contact Lenses For Single Vision Correction

You may be wondering if you will need different contacts if you only have a problem with either your near or distance vision. This is a good question, as contacts are designed a little bit differently than glasses lenses. If you only need single vision lenses, the same types of contacts are used but in a different way:

  • Multifocal Lenses While these contacts are designed with multiple areas of focus, if you only need your near or distance vision corrected, one area of focus can be set at 0.
  • Monovision Lenses With these contact lenses, you will wear a contact lens in only one eye to correct either your distance or near vision.

If you are uncertain which option is best for you, it is a good idea to speak with your optometrist. They can advise you regarding the options available when it comes to contact lenses.
