A lot of people struggle with poor vision, which can make everyday tasks challenging. It’s really important to take care of our eyes – after all, they’re one of our most vital and sensitive organs. Glasses can help correct vision, but not everyone likes wearing them. They might feel that glasses ruin their look or get in the way of their work.
One alternate solution is contact lenses. Now here’s an interesting history piece – the first contact lens was invented by Fick, a Swiss physician, back in 1887. It was made from glass, which wasn’t comfortable and could even be dangerous. But with advancing time and technology, we got plastic lenses in 1938, and by 1950, lenses made from silicone. These modern lenses could cover the entire eye safely and provide really good vision, without harming the delicate cornea.
There are different types of contact lenses available, with each serving a specific purpose. First up, we have Rigid Contact Lenses, made from hard plastic. They were next in line after the original glass lenses, but they were still uncomfortable because they didn’t allow oxygen to reach the eye.
Then came the Soft Contact Lenses, made from a material called HEMA. They soak up water, making them flexible enough to shape perfectly to the eye. Comparatively, these are much more comfortable than the rigid version.
Lastly, we have the Silicone Contact Lenses, a more advanced option. These lenses are quite popular these days. Since they’re made of silicone, they’re great for your eyes and also help to correct vision issues. They allow more oxygen to flow through, which makes it one of the best lens types you can go for.
Just like other things we use, contact lenses need proper care too. Here are a few tips to help you maintain your lenses well:
– Always wash and dry your hands properly before touching your contact lenses.
– Use your fingertips to handle them, not your nails.
– Make sure to dry your hands with a lint-free towel.
– If you’re using soap before handling contacts, it should be free of oil, perfumes, or lotions.
– Remember to change your contacts within their prescribed time frame, so your eyes don’t feel itchy or fatigued.
In a nutshell, contact lenses have done wonders for improving vision. They’re not just functional, but also have a place in cosmetics, with a range of colored lenses on offer. Truly, they’re one of the biggest game-changers of our time.
