Study Shows Contact Lenses Advantages with Mask Wear

Study Shows Contact Lenses Advantages with Mask Wear

A new study establishes that contact lens wear offers an option for a better vision correction experience than spectacles when paired with face masks, and doing so likely improves adherence to mask use. Conducted by Eurolens Research at the University of Manchester, it is the first work to compare the use of any type of face mask with the two types of vision correction.  The study’s corresponding paper—Using face masks with spectacles versus contact lenses (Maldonado-Codina C, et al.) is now in press with Contact Lens and Anterior Eye, the peer reviewed journal of the British Contact Lens Association.[1] It can be downloaded at no charge via Open Access. “Since mask wear became widespread in early 2020, anecdotal reports of problems with fogging when wearing spectacles have been common. Our work agreed with these reports and revealed additional aspects of mask wear and visual correction that favor contact lens prescribing,” Carole Maldonado-Codina, BSc(Hons), MSc, PhD,…

What brand of contact lenses do you wear?

What brand of contact lenses do you wear?

And on a scale of 1-10 how comfortable are they? I’m trying to find the right daily contacts lenses for me because I have really dry eyes. I just tried monthly contact lenses by clear and they were awful. My right eye was all red and puffy. Plus I hate the hassle of cleaning my contacts lenses. I have both dailies and fortnightlies. Dailies for swimming. I do find though the fortnightlies are better for keeping my eyes wet. This is something which is dependent very much on you. Now to buy contacts you do need a valid prescription that includes the contact brand so you do need to go to your eye doctor and discuss the issue. They should be able to give you trials so you can find the right lenses for you. The other thing you can look at addressing is the cause of your dry eyes.…

What’s the difference between circle lenses and regular contact lenses?

What’s the difference between circle lenses and regular contact lenses?

I have a few questions about circles and regular contact lenses. I have prescribed color contact lenses that last for 6 months – 1 year depending on how often you wear them, and I used to wear glasses before. I recently heard about circle contact lenses and I think it’s to make your eyes look bigger? Am I right? And I also heard it can come in prescriptions and different colors too. The situation is, it cost a LOT of money for my contact lenses and while watching a youtube review video on circle lenses, it cost the girl only $25 and they last a whole year ($50 if prescribed) and that’s WAY cheaper than the lenses I bought. My question is, what’s the difference between circle lenses and regular contact lenses? And do circle lenses come in prescriptions? Can there be colored circle lenses? Please help me out! The…

History Of Contact Lenses

History Of Contact Lenses

1508 Leonardo da Vinci illustrates the concept of contact lenses He describes a method of neutralizing the corneal refractive power by holding the eye in the water. 1632 Rene Descartes of France suggests the corneal contact lens. 1801 Thomas Young uses Descartes' principle to neutralize the cornea while studying astigmatism, refraction, and accommodation. 1887 First contact lens manufactured from glass, and fit to cover the entire eye developed by Muller of Germany. The lens was "scleral" in nature and prevented the eye from drying out. 1888 Fick and Kalt produce the first contact lens with correction. 1936 Contact lenses were first made from plastic by  Optometrist William Feinbloom.

Contact Lens Products and How They Relate to You

Contact Lens Products and How They Relate to You

Contact lenses are small plastic disks, shaped to correct a refractive error such as nearsightedness, farsightedness,  astigmatism, and presbyopia.  Contact lenses are placed directly on the eye, where they float on a film of tears in front of the cornea.  Correct design and fitting of the contact lenses are essential for comfort, safety, and accurate correction. Improvements in contact lenses have made them more comfortable and easier to wear.  For many people, contact lenses offer a relatively safe and effective way of correcting vision problems. Types of Contact Lenses Several types of contact lenses are available to correct nearsightedness and other refractive errors. Rigid (hard) lenses Rigid gas-permeable (RGP) lensesConventional hard (PMMA) lenses (polymethyl methacrylate, or PMMA) Soft (hydrophilic or hydrogel) lenses Soft (hydrophilic or hydrogel) lenses are made of soft, very flexible plastics that absorb water (up to 90% of the lens weight).  Many people find them more comfortable to wear than hard lenses, but hard lenses may provide sharper…

The Origins of Contact Lenses

The Origins of Contact Lenses

Contact lenses are really amazing, we just have to wait for a great party, then we get our soft contact lenses, and the party begins. Now we can have much fun with these little things but we must know the origin of such a good thing. Here we are going to give you all the information you need to get what you want: the origin of contact lenses. There is much debate about the real inventor of our cheap contact lenses but the first who find out a way to get something to improve our vision using these devices was Leonardo Da Vinci. We were drawing sketches about all this stuff. Also, Renato Descartes had an idea about contact lenses using a machine he built. Thomas Young in the 1800s repaired its vision using a tube with water and microscopic lenses. He is known as the father of contact lenses…

Contact Lenses for Astigmatism

Contact Lenses for Astigmatism

Contact lenses can help you if you have Astigmatism because many of them are designed to do just that. We must be clear that there are therapeutic contact lenses and other that you can use it not for health purpose, just to increase your beauty. For many years many people thought contact lenses could not help them, but this is not the case today. Astigmatism is a misshaping of the cornea. What happens is that an eye with this disease focuses the light on two-point, this is not the case for the normal eye which focuses the light just on one point. The shape of the cornea with Astigmatism is like a rugby ball. We must recall that this is a misshape of the cornea. Also, we must say that Astigmatism can be caused by an irregular-shaped lens. If you have Astigmatism, there is good news for you because you…

The process of removing contact lenses sometimes is difficult and many times uncomfortable. It does not matter if they are cheap contact lenses or expensive ones; they all can give you problems sooner or later when you try to pop them out of your eyes. One of the advice that you must follow is to have a plan for this, also you must remain calm if you want to succeed in this. Here is an example of the process that you can follow to remove contact lenses. Put your finger on the lower eyelid and pull the eyelid down.
