Which is better: Glasses or Contact lenses?
There really is no say in which one is better. Both glasses and contact lenses have their separate fan base and some people prefer both. It really depends on who is comfortable with what. Most people don’t mind cleaning dust off of their glasses every now and then while some people have problems with it. Lenses are perfectly safe and yes, you can cry in them. Before switching to contacts or glasses, make sure to ask a doctor about it Compared to glasses, contact lenses are a relatively modern invention but even then these modern inventions might have some cons too. Do contacts really fare against glasses? The answer to this is, not really. Again, as mentioned earlier, it depends on preference. Both glasses and lenses have their fair share of pros and cons but relatively speaking, contacts are better.
Here are some important points to consider before making the decision. Expenses Talking about expenses, contacts are generally more expensive than glasses and require a lot of maintenance which is costly too. In case the contact’s case breaks, there is definitely the need to buy a new one because contacts need to be kept in the case when they are being cleaned or whenever there is a need to carry them. Then the solution also costs money which has to be changed every month, depending on the quantity. It isn't like they are crazy expensive or anything. It’s just that when comparing them to glasses they tend to be more costly. Safety Before buying anything that concerns health and the body. Make sure to ask the doctor about it. Safety should be the top priority before anything and that is why it’s important to know about the products planning to be purchased. Contact lenses have been evolving since the early 80s and have improved a lot. They are completely safe and if the eye care routine is followed thoroughly, there should be no problem.
Comfort This is where contact lenses are better than glasses. Glasses can fall or break when people tend to move a lot which doesn’t happen with contacts. They allow people to run, jog, exercise freely. They are more comfortable when one gets used to them because they don’t come in between when wiping your face or taking off your clothes. People with glasses can’t play sports or have to switch to contacts. People tend to find it annoying to have to put on and take off glasses repetitively. Vision Glasses tend to attract a lot of dirt and get easily smeared by fingerprints which doesn’t happen in lenses. They are also right on your cornea which provides better vision and allows you to see things all around unlike with glasses. Taking these points into consideration and knowing that there are plenty of options available for both contacts and glasses is a smart thing to do. There are disposable lenses too like Acuvue 2 Contact Lens and many more. Hopefully, this has helped make a better decision.
Who came up with the idea to invent contact lenses? Like many inventions, making contact lenses took time and effort. Many personalities were involved in this and they came up with different ideas over many years that helped create this amazing invention. While glasses were created over 700 years ago, contact lenses covering only the cornea have existed for just over 60 years. So read along to gain a little knowledge on how contact lenses came into existence. History of Contact lenses In 1508, the famous Leonardo DaVinci realized that submerging one’s head into a bucket of water could help fix certain vision issues. He wrote “The Codex Of The Eye’, created a glass lens with a funnel to pour water. This proved to be impractical and it was clear that the invention was far ahead of its time.
Then 150 years later, a mathematician named Descarte suggested placing the contacts directly on the cornea was a better idea. But failed because his design didn’t allow blinking and external tubes for support were needed. Later on Thomas Young used Descartes idea and created a prototype in 1801. He tried it on himself using wax and observed that it blurred his vision but that could be corrected with another pair of lenses. In 1823 Sir John Herschel proposed to shred the lens for it to fit the cornea as much as possible. In 1887 F. Muller, German artificial glass eye makers, created contacts to protect the diseased eye and were only used for specific medical purposes. They still had a long way to go because the large contacts needed constant artificial lubrication and the smaller contacts had troubles getting attached to the eye and were dangerous as they were fragile and could break. Besides, they still couldn’t correct visions.
In 1936 William Feinbloom used plastic in lenses, this was safer than the glass ones as it wouldn’t break in the eye. People started to prefer them for obvious reasons and the glass contact lenses were discarded. But the plastic ones could be worn for short periods of time as they were uncomfortable because they covered the whole front eye. Then 12 years later Kevin Touhy created a corneal lens…by accident. While he was sanding down a plastic lens, the scleral part fell off and the remaining material perfectly covered just the cornea. It was still attached, allowing proper movements and blinking. Finally in 1960 soft hydrogel lenses were made by chemists, Wichterle and Lim. They still had complications like they were hard to handle because of high water contents and the optical quality was horrible. Around the 1970s, after a lot of developments, Bionite soft lenses were made available in the United Kingdom and they were far more comfortable. Then a year later they also became available in the US and Canada.
In 1987, disposable contact lenses were out which were safer. Companies like Johnson & Johnson produced lenses like Acuvue 1 Day Moist which are worn in the day and thrown out later. Contact lenses have come a far way, allowing people to see clearly with comfort. Different types of Contact Lenses
Everyone has a choice and if you just happened to choose contact lenses, that’s a good choice. Most people don’t want to go with glasses as it sits on the face, or LASIK surgery. Types of contacts Contact lenses differ from one another based on materials. There are 5 types of contact lenses and based on this knowledge, you can choose the one that fits you best.
Silicone Hydrogel lenses These are the most popular types of lenses. They are made of a type of innovative soft lens material that allows oxygen to pass through them. The oxygen then reaches the front surface of the eye. Hybrid contact lenses These lenses are designed in such a way that provides better comfort than soft silicone lenses. They are surrounded by a layer of hydrogel or silicone hydrogel material and have a rigid permeable central zone. PMMA lenses These rigid lenses look like GP lenses but differ because they’re made of plastic that doesn’t permit oxygen. PMMA were usually prescribed years ago but GP lenses took over.
Gas permeable lenses. A.K.A GP or RGP lenses are rigid contact lenses that stay on the eye maintaining shape. This enables them to correct astigmatism or other refractive errors. GP lenses are made of highly oxygen-permeable materials. It takes a little time getting used to them but once that happens, you might find them better than soft lenses. Soft lenses They are made from Hydrogels, they are something like gel-water containing plastics. They are very thin and easily stay on the eye making them extremely comfortable. There comes disposable lenses too like Acuvue 1 Day Moist, biofinity six pack monthly, etc. Once you get used to lenses you will know how easy it is with them. If you experience discomfort or something else, visit a doctor.
How contact lenses gain popularity Contact lenses gained are one of the most important inventions in human history. Even though they aren’t credited as such, they have definitely had a massive impact on our lives. They have made our lives convenient. People who wear glasses will tell you how annoying it is to wear them around. Glasses are bulky and expensive. They can fall off easily and get damaged. Almost everyone who wears corrective glasses is bound to complain about them Contact lenses were not different in the start. They had a lot of problems. Initial problems with contact lenses Da Vinci was the first person to suggest that human vision can be altered by placing the cornea directly in water. However, this idea was very impractical. The first contact lens was made in 1887 from glass and fitted over the entire eye.
These initial contact lenses were quite irritable as they did not allow much oxygen to pass through them. This meant that the oxygen-carrying tears could not pass under the lens and on the cornea. This resulted in dry eyes. Additionally, contact lenses were hard to take care of and caused frequent damage to the eyes. Technological improvements Technology has been improving at a rapid pace. This is because one technological advancement aids in the development of the other and the chain keeps growing. We as a species have evolved enough to fix and enhance our vision quite literally.
2002 Silicone-hydrogel contact lenses These lenses allowed oxygen-carrying tears to pass under the lens making them less irritable. The popularity of contact lenses skyrocketed with these. Now lenses like Acuvue 2 contact lenses are custom lenses that can fit any cornea shape.
The advancements in technology have made contact lenses more convenient and less obtrusive over time. This has made them ever so popular.
