How to Wear Contact Lenses 600 400 jometry1

Nervous? Don’t be. Putting contact lenses in and taking them out is easier than you might think. It may take a few days for your eyes to get used to the feeling of wearing lenses. If you’re having trouble don’t force it, give yourself plenty of time to get comfortable. There’s no rush, you can always try again tomorrow.

Daily Disposable Contact Lenses

Care
Daily disposable contacts are inserted on the eye every morning and thrown away every night, so you don’t need care solutions.

Lifestyle
One and done is an easy care routine for many first-time wearers or people with active lifestyles.

2-Week Contact Lenses

Care
Simply clean daily and store in lens solution overnight to maintain safety and cleanliness.

Lifestyle
2-week contacts require basic care and upkeep, but also enable you to have one pair for a longer period of time than just a day.

Monthly Contact Lenses

Care
Basic care and upkeep—storing and cleaning in lens solution overnight—allows you to keep them for an extended period of time.

Lifestyle
Because you’ll have these longer, they require some amount of responsibility to keep them clean.

 

Polycarbonate vs. Trivex Eyeglasses
Polycarbonate vs. Trivex Eyeglasses 450 300 jometry1

When Eye Safty  is a concern, polycarbonate or Trivex lenses usually are the best choice for your eyeglasses, sunglasses and sports eyewear.

Both polycarbonate and Trivex lenses are thinner and lighter than regular plastic lenses. They also offer 100 percent protection from the sun’s harmful UV light and are up to 10 times more impact-resistant than plastic or glass lenses.

This combination of lightweight comfort, UV protection and impact resistance also makes these lenses an excellent choice for children’s glasses and safety glasses.

Polycarbonate Lenses

polycarbonate lenses have become the standard for safety glasses, sports goggles and children’s eyewear. Because they are less likely to fracture than regular plastic lenses, polycarbonate lenses also are a good choice for rimless eyewear designs where the lenses are attached to the frame components with drill mountings.

  • Light weight (Up to 20% lighter and thinner than plastic CR-39)
  • Impact-resistant lenses. (up to 10 times more impact-resistant )
  • UV Protection (100% UV Protection So if you chose Polycarbonate Lenses, don’t pay for UV coating )

Trivex Lenses

  • Thickness. Polycarbonate has a higher index of refraction than Trivex (1.58 vs. 1.53), so polycarbonate lenses are about 10 percent thinner than Trivex lenses.
  • Weight. Trivex has a lower specific gravity than polycarbonate, making Trivex lenses about 10 percent lighter than polycarbonate lenses.Index-Comparison
  • Optical clarity (central). Trivex lenses have less internal stress and may produce sharper central vision than polycarbonate lenses.
  • Optical clarity (peripheral). Trivex lenses have a higher Abbe value and may produce sharper peripheral vision with less chromatic aberration than polycarbonate lenses.
  • Impact resistance. Polycarbonate and Trivex lenses have comparable impact resistance.
  • UV protection. Polycarbonate and Trivex lenses both block 100 percent of the sun’s UV rays without the need for special UV-blocking lens coatings.
  • Availability. Polycarbonate lenses are available in a wider variety of lens designs ( progressive lenses and other multifocals) than Trivex lenses.
